Introduction While indoor smoking restrictions are common, outdoor restrictions are still rare. We explored opinions and support for regulating smoking in different indoor and outdoor environments among adults who smoke and those who recently quit smoking, in Spain. Methods The 2021 ITC EUREST-PLUS Spain Survey is a cross-sectional study conducted among a nationally representative sample of 1006 adults aged ≥18 years who smoked cigarettes (n=867) or had recently quit smoking (n=139). Using Poisson regression with robust variance, we estimated adjusted prevalence and prevalence ratios of favorable opinions on regulating smoking in different indoor and outdoor environments and support for regulation in unregulated outdoor environments, by sociodemographic and smoking-related characteristics. Results There were highly favorable opinions for regulating smoking in places with minors (>95% in primary and secondary playgrounds, and cars with preschool children and minors) and outdoor transportation (60–80%). There were less favorable opinions for regulating smoking in outdoor terraces of bars/pubs and restaurants (15–20%). Support for further total outdoor regulations on smoking was moderate for markets/shopping centers, public building entrances and swimming pools (40–60%), and low for restaurants/bars/pubs (29.2%). Having quit smoking, having no significant others who smoke and/or believing that cigarette smoke is harmful to others, were factors positively associated with favorable opinions and support for regulating smoking. Conclusions The settings in Spain with the most favorable opinions for regulation among adults who smoke and have recently quit smoking are places with minors, private cars with others and outdoor areas of public transportation, while the settings with the least favorable opinions were outdoor terraces of bars, pubs, and restaurants. Support for further total outdoor smoking bans is generally moderate, but low for restaurants, bars, and pubs. Overall, these findings suggest the feasibility of extending smoke-free policies to other public and private settings to protect others from tobacco smoke exposure.

Objective: This study estimated prevalence of current electronic nicotine delivery systems (ENDS) used by US adults who smoked cigarettes or formerly smoked in 2022 and assessed ENDS flavors, devices, and brands used most often. Methods: Data are from the 2022 US ITC Smoking and Vaping Survey. Respondents were recruited from a web panel of a nationally representative sample of US adults ages 18+ who smoked, formerly smoked, and/or vaped ENDS. Using weighted data, we estimated prevalence of current vaping among adults who smoke or formerly smoked (N = 2,016). Among the subset who vaped (n = 554), we assessed flavors and devices used most often. Using unweighted data, we assessed the frequency (count) of reported brands used most often. Results: In 2022, 22.0 % of US adults who smoked or formerly smoked were vaping at least monthly. A significantly higher proportion of adults who formerly smoked and/or were younger (18–39) were vaping than adults who were smoking and/or were older (40+) (both p

Introduction Non-combustible nicotine products (NCNPs), such as heated tobacco products (HTPs) and nicotine vaping products (NVPs) have gained a significant nicotine market share in South Korea. This descriptive study examined patterns of regular cigarette and NCNP use among South Korean adults. Methods Data were from the 2020 International Tobacco Control Korea Survey and included 4016 adults (aged ≥19 years) in the Republic of Korea who were regularly (at least weekly) using at least one NCNP (NVP/HTP, n=2117) and/ or smoked cigarettes (n=3763) at the time of the survey. Weighted descriptive estimates were computed to assess respondents’ nicotine product use among all respondents (exclusive, dual, or triple use). Thereafter, we identified sociodemographic characteristics associated with NCNP use (n=2117). Results Among Korean adults who were smoking cigarettes, 83.1% (95% CI: 81.6– 84.6) did so exclusively, and 16.9% (95% CI: 15.4–18.4) smoked cigarettes and used NCNPs. Among those who used HTPs (n=1877), 14.9% (95% CI: 11.5–18.4) did so exclusively, 59.6% used HTPs and smoked cigarettes (95% CI: 55.4–63.1), 4.2% used HTPs and vaped (95% CI: 11.5–18.4), and 21.6 % (95% CI: 18.9–24.2) used all three products. Of adults who used HTPs and smoked cigarettes, 86.6% smoked daily. Among those who vaped (n=865), 13.3% did so exclusively (95% CI: 9.4–17.1), 55.6% (95% CI: 49.6–61.5) vaped and smoked cigarettes, 5.1% (95% CI: 1.7–8.6) used HTPs and vaped, and 26.1% (95% CI: 22.1–30.1) used all three products. Of adults who vaped and smoked cigarettes, 82.4% (95% CI: 77.1–87.7) smoked daily. Conclusions Cigarettes remain the most commonly used nicotine product in South Korea, and among adults using heated tobacco and/or vaping products, the majority were also smoking. Research is urgently needed to assess whether adults who are using an NCNP are doing so to quit, or rather to complement their cigarette smoking.

Abstract Background Targeted marketing of menthol cigarettes in the US influences disparities in the prevalence of menthol smoking. There has been no analysis of sub-national data documenting differences in use across demographic subgroups. This study estimated trends in the prevalence of menthol use among adults who smoke in the nine US census divisions by sex, age, and race/ethnicity from 2002 to 2020. Methods Data from 12 waves of the US ITC Survey were used to estimate the prevalence of menthol cigarette use across census divisions and demographic subgroups using multilevel regression and post-stratification (n = 12,020). Multilevel logistic regression was used to predict the prevalence of menthol cigarette use in 72 cross-classified groups of adults who smoke defined by sex, age, race/ethnicity, and socioeconomic status; division-level effects were fit with a random intercept. Predicted prevalence was weighted by the total number of adults who smoke in each cross-classified group and aggregated to divisions within demographic subgroup. Estimates were validated against the Tobacco Use Supplement to the Current Population Survey (TUS-CPS). Results Overall modeled prevalence of menthol cigarette use was similar to TUS-CPS estimates. Prevalence among adults who smoke increased in each division from 2002 to 2020. By 2020, prevalence was highest in the Middle (46.3%) and South Atlantic (42.7%) and lowest in the Pacific (25.9%) and Mountain (24.2%) divisions. Prevalence was higher among adults aged 18–29 (vs. 50+) and females (vs. males). Prevalence among non-Hispanic Black people exceeded 80% in the Middle Atlantic, East North Central, West North Central, and South Atlantic in all years and varied most among Hispanic people in 2020 (Pacific: 26.5%, New England: 55.1%). Conclusions Significant geographic variation in the prevalence of menthol cigarette use among adults who smoke suggests the proposed US Food and Drug Administration (FDA) menthol cigarette ban will exert differential public health benefits and challenges across geographic and demographic subgroups.

Introduction Heated tobacco products (HTPs) and nicotine vaping products (NVPs) both are legal consumer products in the Republic of Korea. Little is known about perceptions of harmfulness of HTPs and NVPs relative to cigarettes in South Korea among adults who smoke, and how exposure to marketing may be associated with harmfulness perceptions. Methods This study used data from the 2020 International Tobacco Control (ITC) Korea Survey, and included 3713 adult (aged 19 years) cigarette smokers who were: 1) exclusive smokers (n=1845); 2) dual HTP + cigarette consumers (n=1130); 3) dual NVP + cigarette consumers (n=224); and 4) triple consumers (all three products, n=514). Weighted multinomial regression models were conducted to estimate smokers’ perceptions of harmfulness of HTPs and NVPs compared to cigarettes, NVPs to HTPs, and self-reported exposure to HTP/NVP advertising. Analyses compared the perceptions of harmfulness between the four different consumer groups, and tested whether exposure to HTP/NVP advertising was associated with perceptions of lower relative harm. Results Among all respondents, 27.5% believe that HTPs are less harmful than cigarettes and 23.4% believe that NVPs are less harmful than cigarettes. Exclusive cigarettes smokers were significantly less likely to perceive that HTPs and NVPs are less harmful than cigarettes compared to dual HTP + cigarette consumers, dual NVP + cigarette consumers, and triple consumers (all p

Introduction In March 2020, the US Food and Drug Administration (FDA) finalized new pictorial health warnings (PHWs), covering 50% of the front and back of the pack; however, legal challenges from cigarette manufacturers have prevented the new warnings from being implemented. About 70% of adults in the general US population support PHWs. This study assessed support for PHWs in 2016, 2018 and 2020 among US adults (aged ≥18 years) who currently smoke or formerly smoked cigarettes. We also assessed factors related to support. Methods Respondents included adults who currently or formerly smoked cigarettes and participated in at least one wave of the US ITC Smoking and Vaping Surveys: Wave 1 (2016, n=2557); Wave 2 (2018, n=2685); and Wave 3 (2020, n=1112). We assessed changes in support for PHWs between 2016 and 2020, and assessed factors related to support (support vs oppose/don’t know). Analyses were conducted on weighted data. Results Overall, 38.0% of respondents supported PHWs in 2016, with a significant increase to 44.7% in 2018 (p

Objective: Introduction of brain hypoxia by frequent mask-wearing is a concern voiced by some who resist masking mandates. Studies have examined acute effects of one-shot mask-wearing on peripheral and cerebral oxygenation in the laboratory, but not effects of everyday mask-wearing frequencies on task-related functional activation. The objective of the current study was to examine whether frequency of mask-wearing in daily life is associated with lower task-related brain oxygenation levels, and whether the magnitude of any such effects vary by age and sex. Methods: Participants were 78 community-dwelling adults between the ages of 18 and 84 years, all of whom were vaccinated at the time of participation; 65.4% (n = 51) were female. Frequency of mask-wearing was assessed using survey questions on mask-wearing practice during an active COVID-19 mask mandate. Recordings of task-related cerebral oxygenation were taken during the completion of a simple reaction time task using 16-channel functional near-infrared spectroscopy (fNIRS). Results: The psychomotor vigilance task elicited reliable increases in cerebral oxygenation within the right mid-frontal gyrus (F(1,61.345) = 15.975, p

Abstract Background Early in the COVID-19 pandemic, reports about a possible protective effect of nicotine on COVID-19 conflicted with messaging by public health organizations about increased risks of COVID-19 due to smoking. The ambiguous information the public received, combined with COVID-19-induced anxiety, may have led to changes in tobacco or other nicotine product use. This study examined changes in use of combustible cigarettes (CCs), nargila (hookah/waterpipe), e-cigarettes, and IQOS and home-smoking behaviors. We also assessed COVID-19 related anxiety and perceptions regarding changes in risk of COVID-19 severity due to smoking. Methods We used cross-sectional data from a population telephone survey that was conducted in Israel in the early phase of the COVID-19 pandemic (May–June 2020) and included 420 adult (age 18+) individuals who reported having ever used CCs (n = 391), nargila (n = 193), and/or electronic cigarettes (e-cigarettes)/heated tobacco products (e.g., IQOS) (n = 52). Respondents were asked about the effect that COVID-19 had on their nicotine product use (quit/reduced use, no change, increased use). We assessed changes in product use, risk perceptions, and anxiety using adjusted multinomial logistic regression analyses. Results Most respondents did not change their frequency of product use (CCs: 81.0%, nargila: 88.2%, e-cigarettes/IQOS: 96.8%). A small percentage either decreased use (CCs: 7.2%, nargila: 3.2%, e-cigarettes/IQOS:2.4%) or increased use (CCs:11.8%, nargila:8.6%, e-cigarettes/IQOS:+ 0.9%). 55.6% of respondents used a product in the home prior to COVID-19; but during the first lockdown COVID-19 period, a greater percentage increased (12.6%) than decreased (4.0%) their home use. Higher levels of anxiety due to COVID-19 were associated with increased home smoking (aOR = 1.59, 95% CI:1.04–2.42, p = 0.02). Many respondents believed that increased severity of COVID-19 illness was associated with CCs (62.0%) and e-cigarettes/vaping (45.3%), with uncertainty about the association being lower for CCs (20.5%) than for vaping (41.3%). Conclusions While many respondents believed that nicotine product use (particularly CCs and e-cigarettes) was associated with increased risk of COVID-19 disease severity, the majority of users did not change their tobacco/nicotine use. The confusion about the relationship between tobacco use and COVID-19 calls for clear evidence-based messaging from governments. The association between home smoking and increased COVID-19-related stress suggests the need for campaigns and resources to prevent smoking in the home, particularly during times of stress.

Abstract Background The cost of tobacco is one of the most reported reasons for smoking cessation. Rather than quitting, smokers can use also strategies to reduce tobacco expenditure while continuing smoking, such as smoking less or using price-minimising strategies. The Netherlands announced to increase the price of a pack cigarettes from seven (2018) to ten euros (2023), to reduce tobacco prevalence and consumption. This study explores the self-reported strategies to reduce tobacco spending among Dutch smokers, and whether this differed per age, income, and education. Additionally, we analysed among quitters in these subgroups whether price played a role in their decision to quit. Methods Cross-sectional survey data from the International Tobacco Control (ITC) Netherlands Wave 2 (September–November 2020, N = 1915) was used. Strategies to reduce spending among smokers (N = 1790) were: reducing consumption, bulk buying, switching to cheaper products or buying from low-taxed sources. These were collapsed into: reducing consumption (solely or in combination with other behaviours), solely price-minimising behaviours (such as buying cheaper brands), or no strategies to reduce spending. Associations between strategies and characteristics were analysed through multinomial and binary logistic regression models. Second, we explored which subgroups were more likely to report that price played a role in their decision to quit among quitters (N = 125). Results The majority of smokers used strategies to reduce tobacco spending: 35.6% reduced consumption and 19.3% used solely price-minimising strategies. 82.1% of quitters reported that price played a role in their decision to quit. Low-income individuals were more likely to report price as a reason for quitting and reduce consumption, but also to buy cheaper products. Highly nicotine dependent smokers were more likely to use price-minimising behaviours, and less likely to reduce consumption. Conclusions The majority reported using strategies to reduce spending or that price played a role in their decision to quit. Reducing consumption was the most reported strategy. Low-income smokers were more likely to reportedly reduce consumption, buy cheaper products, or quit. Price policies have the potential to reduce socioeconomic inequalities in smoking. To discourage price-minimising behaviours, such as switching to cheaper products, reducing price differences between products should be prioritized.

Introduction Transitions between different tobacco products are frequent among tobacco users in Bangladesh; however, the reasons leading to such transitions and why they quit are not well researched. The aim of the study is to examine perceptions and reasons reported by tobacco users in Bangladesh to transition to other products or quit. Methods Data from four waves (2009–2015) of the International Tobacco Control (ITC) Bangladesh Survey were used. Repeated data on perceptions and reasons for exclusive cigarette (n=520), bidi (n=130), and SLT users (n=308) to either start using other products or quit were analyzed with sampling weights. The percentages of responses across waves were used to calculate the pooled proportion data using a meta-analysis approach. Results Common reasonsig for respondents switching to other tobacco products were influence of friends/family (73.8–86.0%), and curiosity (44.4–71.3%). The perceived calming effect of smoking cigarettes and bidis (43.2–56.9%), and the impression that bidis were less harmful (52.3%) and taste better (71.2%) were major reasons for exclusive SLT users to switch products. Health concerns (16.5– 62.7%) and disapproval from friends/family (29.8–56.4%) were generally the main reasons for quitting. For smoked tobacco users, doctor’s advice (41.6%), package warning labels (32.3%), and price (32.4%) seemed to be the major driving factors to quit. Conclusions Results highlight that the reasons for switching between tobacco products and quitting include social factors (e.g. friends/family) and (mis) perceptions regarding the products. Tobacco control policy could emphasize cessation support, increased price and education campaigns as key policies to reduce overall tobacco use in Bangladesh. Data from four waves (2009–2015) of the International Tobacco Control (ITC) Bangladesh Survey were used. Repeated data on perceptions and reasons for exclusive cigarette (n=520), bidi (n=130), and SLT users (n=308) to either start using other products or quit were analyzed with sampling weights. The percentages of responses across waves were used to calculate the pooled proportion data using a meta-analysis approach.

Abstract Background Previous research in high-income countries (HICs) has shown that smokers reduce their cognitive dissonance through two types of justifications over time: risk minimizing and functional beliefs. To date, however, the relationship between these justifications and smoking behaviors over time has limited evidence from low- and middle-income countries. This study examines these of justifications and their relation to quitting behavior and intentions among smoking tobacco users in India. Methods The data are from the Tobacco Control Policy (TCP) India Survey, a prospective cohort of nationally representative sample of tobacco users. The respondents include smoked tobacco (cigarettes and bidi) users (n = 1112) who participated in both Wave 1 (W1; 2010–2011) and Wave 2 (W2; 2012–2013) surveys. Key measures include questions about psychosocial beliefs such as functional beliefs (e.g., smoking calms you down when you are stressed or upset) and risk-minimizing beliefs (e.g., the medical evidence that smoking is harmful is exaggerated) and quitting behavior and intentions at Wave 2. Findings Of the 1112 smokers at W1, 78 (7.0%) had quit and 86 (7.8%) had intentions to quit at W2. Compared to W1, there was a significant increase in functional beliefs at W2 among smokers who transitioned to mixed use (using both smoking and smokeless tobacco) and a significant decrease among those who quit. At W2, smokers who quit held significantly lower levels of functional beliefs, than continuing smokers, and mixed users ((M = 2.96, 3.30, and 3.93, respectively, p

Several nicotine vaping product (NVP) device types are available to consumers, and many people who smoke report vaping to help them quit. This study included data from the Wave 3 (2020) ITC Smoking and Vaping Survey in the US, Canada, and England and included 2324 adults who were smoking cigarettes and vaping at least weekly. Device types currently used most often (disposables, cartridges/pods, or tank systems) were assessed using weighted descriptive statistics. Multivariable regression analyses were used to compare differences between respondents who reported vaping to quit smoking (‘yes’ vs. ‘no/don’t know’) by device type, overall and by country. Overall, 71.3% of respondents reported vaping to help them quit smoking, with no country differences (p = 0.12). Those using tanks (78.7%, p

Objective: The objective of the current investigation was to examine associations between symptomatic COVID-19 history, neurocognitive function, and psychiatric symptoms using cognitive task performance, functional brain imaging, and a prospective population survey. Methods: Study 1 was a laboratory study conducted between 3 May 2022 and 16 Nov 2022 involving 120 fully vaccinated community dwelling adults between 18 and 84 years of age (Mage = 31.96 (SD = 20.71), 63.3% female). In this cross-sectional study we examined the association between symptomatic COVID-19 infection history and performance on three computer tasks assessing cognitive function (Flanker interference, delay discounting and simple reaction time) and measured oxygen saturation within the prefrontal cortex using functional near infrared spectroscopy (fNIRS). Study 2 was a 2-wave population survey undertaken between 28 September 2021 and 21 March 2022, examining the prospective relationship between symptomatic COVID-19 and self-reported symptoms of cognitive dysfunction, depressive symptoms, anxiety symptoms, and agitation at 6-month follow up. The sample (N = 2,002, Mage = 37.0, SD = 10.4; 60.8% female) was collected using a quota process to ensure equal numbers of vaccinated and unvaccinated individuals. Structural equation modelling with latent variables was performed on the population-level data, evaluating the fit of the proposed mediational model of symptomatic COVID-19 to psychiatric symptoms through cognitive dysfunction. Results: Findings from Study 1 revealed significant effects of symptomatic COVID-19 history on Flanker interference and delay discounting. Effects on flanker performance were significantly stronger among older adult women (effect: 9.603, SE = 4.452, t = 2.157, p = .033), and were accompanied by task-related changes cerebral oxygenation at the right superior frontal gyrus (F (1, 143.1) = 4.729, p = .031). Additionally, those with a symptomatic COVID-19 infection history showed evidence of amplified delay discounting (coefficient = 0.4554, SE = 0.2208, t = 2.0629, p = .041). In Study 2, baseline symptomatic COVID-19 history was associated with self-reported cognitive dysfunction and a latent variable reflecting psychiatric symptoms of anxiety, depression and agitation at follow-up. Mediational analyses revealed evidence of cognitive mediation of clinically significant psychiatric outcomes: depression (indirect effect = 0.077, SE = 0.026, p = .003) and generalized anxiety (indirect effect = 0.060, SE = 0.021, p = .004). Conclusions: Converging findings from laboratory and population survey data support the conclusion that symptomatic COVID-19 infection is associated with task-related, functional imaging and self-reported indices of cognitive dysfunction as well as psychiatric symptoms. In some cases, these findings appear to be more amplified among women than men, and among older women than younger.

The ITC Malaysia Project is part of the 31-country ITC Project, of which the central objective is to evaluate the impact of tobacco control policies of the WHO Framework Convention on Tobacco Control (FCTC). This article describes the methods used in the 2020 International Tobacco Control (ITC) Malaysia (MYS1) Survey. Adult smokers and non-smokers aged ≥18 years in Malaysia were recruited by a commercial survey firm from its online panel. Survey weights, accounting for smoking status, sex, age, education, and region of residence, were calibrated to the Malaysian 2019 National Health and Morbidity Survey. The survey questions were identical or functionally similar to those used in other ITC countries. Questions included demographic measures, patterns of use, quit history, intentions to quit, risk perceptions, beliefs and attitudes about cigarettes, e-cigarettes, and heated tobacco products. Questions also assessed measures assessing the impact of tobacco demand-reduction domains of the FCTC: price/tax (Article 6), smokefree laws (Article 8), health warnings (Article 11), education, communication and public awareness (Article 12), advertising, promotion, and sponsorship restrictions (Article 13), and support for cessation (Article 14). The total sample size was 1253 (1047 cigarette smokers and 206 non-smokers). Response rate was 11.3%, but importantly, the cooperation rate was 95.3%. The 2020 ITC MYS1 Survey findings will provide evidence on current tobacco control policies and evidence needed by Malaysian government regulatory agencies to develop new or strengthen existing tobacco control efforts that could help achieve Malaysia’s endgame, i.e. a tobaccofree nation by 2040.

Introduction Malaysia has the largest e-cigarette (EC) market in Southeast Asia, and it has been estimated that 17% of adult daily cigarette smokers also used ECs on a daily basis in 2020. However, few studies have examined the reasons people use ECs in Malaysia. This cross-sectional study of adult cigarette smokers from Malaysia assessed reasons for EC use and their support for key proposed EC regulations. Material and Methods Data are from the 2020 International Tobacco Control (ITC) Malaysia Wave 1 Survey of adult (aged ≥18 years) smokers who reported that they used ECs at least monthly (N=459 out of 1047 smokers). Weighted analyses were conducted on EC users’ reasons for using ECs and their support for various EC regulations. Results Smokers who used ECs at least monthly were more likely to be male, aged 25–39 years, of Malay ethnicity, married, more highly educated, and living in Peninsular Malaysia. Smokers who used ECs daily reported using ECs to reduce the number of cigarettes smoked (91.3%), pleasant taste (90.1%), to quit smoking (87.9%), and enjoyment (87.5%). Smokers who used ECs less than daily reported using ECs for their pleasant taste (weekly 89.4%, monthly 87.5%), curiosity (weekly 79.5%, monthly 88.8%), being offered EC by someone (weekly 76.3%, monthly 81.6%), and to reduce the number of cigarettes smoked (weekly 76.2%, monthly 77.6%). Smokers who also used ECs were most likely to support EC regulations requiring a minimum purchasing age (88.3%) and limiting nicotine concentration (79.6%), and least likely to support regulations banning EC fruit and candy flavors (27.1%). Conclusions The most prevalent reasons for using ECs in Malaysia are comparable to those of other ITC countries, including Canada, US, England, and Australia. An understanding of use patterns of ECs, especially their interaction with cigarettes, are important in developing evidence-based regulations in Malaysia.

Introduction E-cigarettes (ECs) have become increasingly common in many countries, including Malaysia. The prevalence of EC use increased in Malaysia from 0.8% in 2011 to 4.9% in 2019. Three quarters of Malaysian EC users also smoke combustible cigarettes, and the prevalence of EC use among Malaysian smokers in 2014 was consistent with the prevalence of use among smokers from Canada and the US in 2016. The purpose of this study was to estimate the prevalence of EC use among Malaysian adults aged ≥18 years in 2020 and the types of EC products and flavors used by cigarette smokers who also used ECs at least monthly. Methods Data came from 1253 adults aged ≥18 years who participated in the 2020 International Tobacco Control Malaysia Wave 1 Survey. Weighted descriptive statistics were used to estimate the prevalence of adults who reported ever using ECs and the prevalence who used ECs either monthly, weekly, or daily. The types of EC products and flavors used were compared by frequency of EC use among current smokers who used ECs at least monthly (n=459). Results Overall, 5.4% (95% CI: 3.7–7.5) of Malaysian adults reported using ECs on a daily basis in 2020. Among current cigarette smokers who used ECs daily, 81.0% (95% CI: 72.5–87.7) used nicotine in their ECs, 46.2% (95% CI: 37.8–54.7) used pre-filled ECs, and 60.4% (95% CI: 51.9–68.6) reported being somewhat/very addicted to ECs. The most common EC flavors were fruit, coffee, and menthol/ mint. Conclusions Continued surveillance of EC use is necessary to monitor EC use in non-tobacco using populations while longitudinal research is needed to determine the extent to which ECs are, or are not, related to quitting smoking.

Aims: In 2014, in response to evidence that Canada’s tobacco use would lead, inexorably, to substantial morbidity and mortality for the foreseeable future, a group of experts convened to consider the development of a “Tobacco Endgame” for Canada. The “Tobacco Endgame” defines a time frame in which to eliminate structural, political, and social dynamics that sustain tobacco use, leading to improved population health. Strategies: A series of Background Papers describing possible measures that could contribute to the creation of a comprehensive endgame strategy for Canada was prepared in advance of the National Tobacco Endgame Summit hosted at Queen’s University in 2016. At the summit, agreement was reached to work together to achieve 5 million smokers in Canada, signaling that smoking-related diseases will continue to be an enormous health burden. Furthermore, the landscape of new products (e-cigarettes and cannabis) has created additional risks and opportunities. Future directions: A bold, reinvigorated tobacco control strategy is needed that significantly advances ongoing policy developments, including full implementation of the key demand-reduction policies of the WHO Framework Convention on Tobacco Control. Formidable, new disruptive policies and regulations will be needed to achieve Canada’s Endgame goal.

Introduction China has more than 300 million current smokers. There is a controversy over smokers’ risk of COVID-19 infection. Smoking is a risk factor for COVID-19 disease progression, and the outbreak of COVID-19 may change people’s smoking behaviors. This study assessed people’s attitudes towards ‘smoking and COVID-19’ and changes of smoking behaviors before and after the outbreak of COVID-19. Material and Methods A cross-sectional web survey of 11009 adults in China was conducted between 7 May and 3 August 2020. Attitudes towards ‘smoking and COVID-19’ were compared among non-smokers (n=8837), ex-smokers (n=399) and current smokers (n=1773), and changes in smoking behaviors before and after the outbreak of COVID-19 were assessed among current smokers. Results Fewer current smokers (26.2%) agreed with the statement that ‘Current smokers are more likely than ex-smokers or non-smokers to contract COVID-19’ compared with non-smokers (53%) or ex-smokers (41.4%); fewer current smokers (55.9%) agreed with the statement ‘If contracted, current smokers are more likely than ex-smokers or non-smokers to risk disease progression’ compared with nonsmokers (75.5%) or ex-smokers (68.7%). There were no changes in cigarettes smoked per day (mean ± SD: 13.3 ± 9.55 vs 13.4 ± 9.69, p=0.414), percentage of daily smokers (70.8% vs 71.1%, p=0.882) and percentage of smokers with motivation to quit (intend to quit within the next 6 months, 9.4% vs 10.9%, p=0.148) before and after the outbreak of COVID-19. Conclusions The survey found that fewer current smokers agreed that smoking is a risk-factor for COVID-19 compared with non-smokers or ex-smokers. Among current smokers, there were no changes in their cigarette consumption and motivation to quit before and after the outbreak of COVID-19. More efforts are needed to educate smokers about the health risks of smoking, as well as efforts to promote their motivation to quit.

Objective: The ITC EUREST-PLUS Spain Survey is a longitudinal study of a representative sample of Spanish adult (≥18 years old) smokers. This protocol describes the methods of the 2021 follow-up survey. Method: The ITC EUREST-PLUS Survey, a prospective cohort study of a representative sample of smokers in six European countries, was conducted in 2016 (baseline) and 2018 (waves 1 and 2). The 2021 ITC EUREST-PLUS Spain Survey is a continuation of the Spanish cohort with a new interview in 2021 (wave 3). Lost participants were replaced with new smokers recruited using the same multi-stage sampling design. This latest follow-up aims to examine current patterns and transitions of tobacco use and to evaluate the impact of new tobacco-related policies. Comments: The ITC EUREST-PLUS Spain Survey will provide recent information about the impact of tobacco control policies on smoking behaviour. Resumen: Objetivo: La encuesta ITC EUREST-PLUS España es un estudio longitudinal de una muestra representativa de fumadores adultos (≥18 años) españoles. Este protocolo describe los métodos de la encuesta de seguimiento de 2021. Método: La encuesta ITC EUREST-PLUS, un estudio de cohortes prospectivo de una muestra representativa de fumadores en seis países europeos, se realizó en 2016 y 2018 (olas 1 y 2). La encuesta ITC EUREST-PLUS España de 2021 es una continuación de la cohorte española con una nueva entrevista en 2021 (ola 3). Se sustituyeron las pérdidas con nuevos fumadores reclutados usando el mismo diseño muestral multietápico. Este último seguimiento pretende examinar los patrones actuales y las transiciones del uso de tabaco, y evaluar el impacto de nuevas políticas relacionadas con el tabaco. Comentarios: La encuesta ITC EUREST-PLUS España de 2021 proporcionará información reciente sobre el impacto de las políticas de control del tabaco en el consumo de tabaco.

Abstract Objectives: To assess support among smokers and recent quitters for the Smokefree New Zealand (NZ) 2025 goal and measures to facilitate its achievement. Methods: Data from CATI interviews with 1,155 (386 Māori) smokers and recent quitters in Wave 1 (August 2016–April 2017) and 1,020 (394 Māori) in Wave 2 (June–December 2018) of the International Tobacco Control (ITC) NZ Survey. Results: (Wave 2 unless stated): Almost all (95%) participants were aware of and more than half (56%) supported the smokefree goal. Support was highest (69–92%) for measures to reduce smoking uptake and protect children from exposure to secondhand smoke. Support was also high for other smokefree policies including mandated denicotinisation of smoked tobacco products (73%) and tobacco retailer licensing (70%, Wave 1). Support was lowest (

Background: Vaccine hesitancy and inconsistent mitigation behavior performance have been significant challenges throughout the COVID-19 pandemic. In Canada, despite relatively high vaccine availability and uptake, willingness to accept booster shots and maintain mitigation behaviors in the post-acute phase of COVID-19 remain uncertain. The aim of the Canadian COVID-19 Experiences Project (CCEP) is threefold: 1) to identify social-cognitive and neurocognitive predictors of mitigation behaviors, 2) to identify optimal communication strategies to promote vaccination and mitigation behaviors, and 3) to examine brain health outcomes of SARS-CoV-2 infection and examine their longevity. Methods: The CCEP is comprised of two components: a conventional population survey (Study 1) and a functionally interconnected laboratory study (Study 2). Study 1 will involve 6 waves of data collection. Wave 1, completed between 28 September and 21 October 2021, recruited 1,958 vaccine-hesitant (49.8%) and fully vaccinated (50.2%) adults using quota sampling to ensure maximum statistical power. Measures included a variety of social cognitive (e.g., beliefs, intentions) and neurocognitive (e.g., delay discounting) measures, followed by an opportunity to view and rate a set of professionally produced COVID-19 public service announcement (PSA) videos for perceived efficacy. Study 2 employs the same survey items and PSAs but coupled with lab-based eye tracking and functional near-infrared spectroscopy (fNIRS) to directly quantify neural indicators of attention capture and self-reflection in a smaller community sample. In the final phase of the project, subjective impressions and neural indicators of PSA efficacy will be compared and used to inform recommendations for construction of COVID-19 PSAs into the post-acute phase of the pandemic. Discussion: The CCEP provides a framework for evaluating effective COVID-19 communication strategies by levering conventional population surveys and the latest eye-tracking and brain imaging metrics. The CCEP will also yield important information about the brain health impacts of SARS-CoV-2 in the general population, in relation to current and future virus variants as they emerge.

Cigarette gifting is pervasive in China. As the Chinese are increasingly aware of harm from smoking cigarettes, e-cigarettes, often promoted as less harmful alternatives to cigarettes, may be viewed as appropriate gifts. This study is the first using population-based survey data to examine receiving and giving e-cigarettes as gifts in China. We analyzed 9,274 adults from Wave 5 of the International Tobacco Control China Survey, which was completed in July 2015. We found that the prevalence of receiving e-cigarettes as gifts was 1.3% among all respondents and 5.3% among urban smokers; the prevalence of giving e-cigarettes as gifts was 0.5% among all respondents and 1.2% among urban smokers. These prevalence estimates were very low among nonsmokers and rural respondents. Further analysis on urban smokers (N = 3,312) found that those aged 40–54 and 55+, those with high education levels, heavy smokers, and those who perceived e-cigarettes as equally/more harmful than cigarettes were more likely to receive e-cigarette gifts; and those who ever used e-cigarettes were significantly more likely to both receive and give e-cigarette gifts. Urban smokers with positive attitude about cigarette gifting were also more likely to give e-cigarette gifts to others, but those aged 55+ were less likely to gift e-cigarettes. Findings of this study indicate that the Chinese may perceive e-cigarettes as appropriate gifts for smokers, especially heavy smokers. Precautions should be taken to prevent e-cigarettes from becoming a gift choice for nonsmokers. Health campaigns designed to combat the social acceptance of cigarette gifting may also help reduce e-cigarette gifting.

Background: SARS-CoV-2 infection is believed to adversely affect the brain, but the degree of impact on socially relevant cognitive functioning and decision-making is not well-studied, particularly among those less vulnerable to age-related mortality. The current study sought to determine whether infection status and COVID-19 symptom severity are associated with cognitive dysfunction among young and middled-aged adults in the general population, using self-reported lapses in executive control and a standardized decision-making task. Method: The survey sample comprised 1958 adults with a mean age of 37 years (SD ​= ​10.4); 60.8% were female. Participants reported SARS-CoV-2 infection history and, among those reporting a prior infection, COVID-19 symptom severity. Primary outcomes were self-reported symptoms of cognitive dysfunction assessed via an abbreviated form of the Barkley Deficits in Executive Functioning Scale (BDEFS) and performance on a validated delay-discounting task. Results: Young and middle-aged adults with a positive SARS-CoV-2 infection history reported a significantly higher number of cognitive dysfunction symptoms (Madj ​= ​1.89, SE ​= ​0.08, CI: 1.74, 2.04; n ​= ​175) than their non-infected counterparts (Madj ​= ​1.63, SE ​= ​0.08, CI: 1.47,1.80; n ​= ​1599; β ​= ​0.26, p ​= ​.001). Among those infected, there was a dose-response relationship between COVID-19 symptom severity and level of cognitive dysfunction reported, with moderate (β ​= ​0.23, CI: 0.003–0.46) and very/extremely severe (β ​= ​0.69, CI: 0.22–1.16) COVID-19 symptoms being associated with significantly greater cognitive dysfunction. These effects remained reliable and of similar magnitude after controlling for demographics, vaccination status, mitigation behavior frequency, and geographic region, and after removal of those who had been intubated during hospitalization. Very similar—and comparatively larger—effects were found for the delay-discounting task, and when using only PCR confirmed SARS-CoV-2 cases. Conclusions: Positive SARS-CoV-2 infection history and moderate or higher COVID-19 symptom severity are associated with significant symptoms of cognitive dysfunction and amplified delay discounting among young and middle-aged adults with no history of medically induced coma.

Introduction Tobacco companies have introduced heated tobacco products (HTPs), such as IQOS, which may compete with e-cigarettes among smokers interested in switching to potentially reduced-risk products. Non-smokers may also start using IQOS if they believe this product is less harmful than other nicotine products. Smokers’ and non-smokers’ decisions may be driven by relative harm perceptions of emerging nicotine products. We aimed to examine relative harm perceptions between IQOS, e-cigarettes, and cigarettes, among nicotine product users and non-users. Material and Methods We conducted a web survey with Canadian respondents (aged ≥20 years; n=268) in September–October 2018. Perceptions about relative harm between IQOS (available for sale since 2017 and subject to the same comprehensive marketing restrictions as cigarettes in Canada), e-cigarettes, and cigarettes, were assessed among non-users (n=79), exclusive smokers (n=78), exclusive e-cigarette users (n=32), and dual users (n=79). Multiple logistic regression explored the association between relative harm perceptions and nicotine-use status, adjusting for sociodemographic variables. Results Over half of respondents perceived IQOS as equally or more harmful than e-cigarettes (53.7%), while almost a quarter either reported IQOS as less harmful than e-cigarettes or were uncertain (22.7% and 23.5%, respectively). Two-thirds of respondents (65.7%) perceived e-cigarettes as less harmful than cigarettes, yet only half (48.1%) perceived IQOS as less harmful than cigarettes. Both exclusive and dual e-cigarette users, but not exclusive smokers, had higher odds of perceiving IQOS as more harmful than e-cigarettes and less harmful than cigarettes compared to non-users. Conclusions Most nicotine users and non-users perceive differential health risk across IQOS, e-cigarettes, and cigarettes. Although e-cigarettes are generally viewed as less harmful than cigarettes, the perceived harm of IQOS was unclear.

Abstract Background Although recreational cannabis is now legal in Canada, little empirical evidence exists regarding young Canadians’ cannabis literacy, cannabis-related risk perceptions, and risk of different forms of cannabis or the effect that public health education may have on these perceptions. The present study sought to address these knowledge gaps to examine health knowledge and risk perceptions associated with cannabis use. Methods An online survey was conducted with a national sample (N = 870) of Canadians aged 16 to 30 years in October 2017 using a commercial panel. The study examined young Canadians’ awareness of negative health effects related to cannabis, evaluation of known risks, and risk perceptions of different forms of administration. Results Most respondents were aware of a cannabis-related physical health effect (78.0%). Approximately one-third reported having been exposed to public health messaging about cannabis; digital media was reported most frequently. Compared to never users, ever users were less likely to report general likelihood of addiction (p < 0.001) and harm to mental health (p < 0.001). Approximately one-quarter of past 3-month cannabis users reported they were at least “a little” addicted. Respondents who reported using a particular form of cannabis self-administration (e.g., edibles, smokables) were less likely to perceive harm than those who did not use each form (p < 0.001). Conclusions The current study is among the first to measure the knowledge and perceptions of risks of Canadian youth about cannabis. The study, conducted in the time immediately preceding legalization, may serve as a reference point for future studies examining changes in cannabis knowledge and risk perceptions. This will be important in addressing the need for monitoring and enhancing public awareness of the impact and potential harms of this newly legalized substance.

Background: Light and intermittent smoking has become increasingly prevalent as smokers shift to lower consumption in response to tobacco control policies. We examined changes in cigarette consumption patterns over a four-year period and determined which factors were associated with smoking transitions. Methods: We used data from a cohort of smokers from the 2008–2012 ITC Mexico Survey administrations to investigate transitions from non-daily (ND; n = 669), daily light (DL; ≤5 cigarettes per day (cpd); n = 643), and daily heavy (DH; >5 cpd; n = 761) smoking patterns. To identify which factors (i.e., sociodemographic measures, perceived addiction, quit behavior, social norms) were associated with smoking transitions, we stratified on smoking status at time t (ND, DL, DH) and used multinomial (ND, DL) and binomial (DH) logistic regression to examine transitions (quitting/reducing or increasing versus same level for ND and DL, quitting/reducing versus same level for DH). Results: ND smokers were more likely to quit at follow-up than DL or DH smokers. DH smokers who reduced their consumption to ND were more likely to quit eventually compared to those who continued as DH. Smokers who perceived themselves as addicted had lower odds of quitting/reducing smoking consumption at follow-up compared to smokers who did not, regardless of smoking status at the prior survey. Quit attempts and quit intentions were also associated with quitting/reducing consumption. Conclusions: Reducing consumption may eventually lead to cessation, even for heavier smokers. The findings that perceived addiction and quit behavior were important predictors of changing consumption for all groups may offer insights into potential interventions.

Introduction Although recent research shows that smokers respond differently to the COVID-19 pandemic, it offers little explanation of why some have increased their smoking, while others decreased it. In this study, we examined a possible explanation for these different responses: pandemic-related stress. Material and Methods We conducted an online survey among a representative sample of Dutch current smokers from 11–18 May 2020 (n=957). During that period, COVID-19 was six weeks past the (initial) peak of cases and deaths in the Netherlands. Included in the survey were measures of how the COVID-19 pandemic had changed their smoking, if at all (no change, increased smoking, decreased smoking), and a measure of stress due to COVID-19. Results Overall, while 14.1% of smokers reported smoking less due to the COVID-19 pandemic, 18.9% of smokers reported smoking more. A multinomial logistic regression analysis revealed that there was a dose-response effect of stress: smokers who were somewhat stressed were more likely to have either increased (OR=2.37; 95% CI: 1.49–3.78) or reduced (OR=1.80; 95% CI: 1.07–3.05) their smoking. Severely stressed smokers were even more likely to have either increased (OR=3.75; 95% CI: 1.84–7.64) or reduced (OR=3.97; 95% CI: 1.70–9.28) their smoking. Thus, stress was associated with both increased and reduced smoking, independently from perceived difficulty of quitting and level of motivation to quit. Conclusions Stress related to the COVID-19 pandemic appears to affect smokers in different ways, some smokers increase their smoking while others decrease it. While boredom and restrictions in movement might have stimulated smoking, the threat of contracting COVID-19 and becoming severely ill might have motivated others to improve their health by quitting smoking. These data highlight the importance of providing greater resources for cessation services and the importance of creating public campaigns to enhance cessation in this dramatic time.

Abstract Background Displaying tobacco products at point-of-sale (PoS) has become an important marketing strategy for the tobacco industry. This study was designed to (1) examine how support for a PoS cigarette display ban changed among Dutch smokers between 2010 and 2015 and (2) identify the variables that predict support among smokers for a PoS cigarette display ban. Methods Longitudinal data from six annual survey waves (2010-2015) from the International Tobacco Control (ITC) Netherlands Survey were analyzed. The sample consisted of between 1279 and 1800 smokers per year. Smokers were asked whether they supported a complete ban on displays of cigarettes inside shops and stores. Results Support for a PoS cigarette display ban increased from 28.9% in 2010 to 42.5% in 2015 (OR = 1.40, p

Abstract Background Health warnings labels (HWLs) have the potential to effectively communicate the health risks of smoking to smokers and non-smokers, and encourage smokers to quit. This study sought to examine whether non-smokers in China notice the current text-only HWLs and whether they support adding more health information and including pictures on HWLs. Methods Adult non-smokers (n = 1324) were drawn from Wave 4 (September 2011–November 2012) of the International Tobacco Control (ITC) China Survey. The proportion of non-smokers who noticed the HWLs, and supported adding more health information and pictures to the HWLs was examined. Additionally, the relation between non-smokers’ demographic characteristics, including whether they had a smoking partner, their number of smoking friends, and noticing the HWLs and support for adding health information and pictures was examined. Because the HWLs changed during the survey period (April 2012), differences between non-smokers who completed the survey before and after the change were examined. Results 12.2% reported they noticed the HWLs often in the last month. The multivariate model, adjusting for demographics showed that respondents with a smoking partner (OR = 2.41, 95% CI 1.42–4.13, p = 0.001) noticed the HWLs more often. 64.8% of respondents agreed that the HWLs should have more information, and 80.2% supported including pictures. The multivariate model showed that non-smokers who completed the survey after the HWLs were implemented (OR = 0.63, 95% CI 0.40–0.99, p = 0.04) were less likely to support adding more health information. The multivariate model showed a significant relation between having a smoking partner and supporting pictorial HWLs (OR = 2.03, 95% CI 1.24–3.33, p = 0.005). Conclusions The findings indicate that the Chinese HWLs are noticed by a minority of non-smokers and that non-smokers strongly support strengthening the Chinese warning labels with more health information and pictures. Additionally, because the HWLs are noticed more often by non-smokers with a smoking spouse/partner, HWLs could be used to communicate the dangers of smoking and secondhand smoke exposure to non-smokers.

Abstract Background In 2009, after many delays and changes, India introduced a single pictorial health warning label (HWL) on smokeless tobacco (SLT) packing—a symbolic image of a scorpion covering 40% of the front surface. In 2011, the scorpion was replaced with 4 graphic images. This paper tested the effectiveness of SLT HWLs in India and whether the 2011 change from symbolic to graphic images increased their effectiveness. Methods Data were from a cohort of 4733 adult SLT users (age15+) of the Tobacco Control Project (TCP) India Survey from 4 states. The surveys included key indicators of health warning effectiveness, including warning salience, and cognitive, emotional, and behavioral responses to the warnings. Results The HWL change from symbolic to graphic did not result in significant increases on any of the HWL outcome indicators. A substantial minority of SLT users were unaware that SLT packages contained HWLs (27% at both waves). Noticing the warnings was also remarkably low at both waves (W1 = 34.3%, W2 = 28.1%). These effects carried over to the cognitive and behavioural measures, where among those who noticed HWLs, about one-third reported forgoing SLT at least once because of the HWLs, and fewer than 20% reported that HWLs made them think about SLT risks or about quitting SLT. Even fewer reported avoiding HWLs (8.1 to 11.6%). Among those who quit using SLT by post-policy, awareness that SLT packaging contained HWLs was significantly greater at post-policy (86.8%) compared to pre-policy (77.8%, p = 0.02). Quitters were also significantly more aware of the post-policy HWLs compared to those who continued to use SLT (p

Objective Since iQOS was introduced in Japan in 2014, the heated tobacco product (HTP) market has expanded in Japan and globally. Tobacco advertising, promotion, and sponsorship (TAPS) restrictions in Japan are self-regulated by the industry, and no forms of TAPS are banned under national law. This study examines awareness of cigarette and HTP marketing, and support for TAPS bans in Japan. Methods Data are from the International Tobacco Control (ITC) Japan Wave 1 (2018) Survey, a web-based survey of adult cigarette smokers, dual users of cigarettes and HTPs, and non-smokers/non-HTP users (n=4,684). Measures included noticing cigarette and HTP advertising in the last 6 months; and support for bans on cigarette and HTP POS displays, cigarette advertising, and price promotions in stores. Weighted logistic regression models examined exposure to cigarette and HTP marketing and support for TAPS bans among HTP users (n=555 dual users and n=207 HTP-only users) and HTP non-users (n=3,306 cigarette smokers and n=616 non-smokers). Results Retail stores were the most common source of cigarette and HTP advertising with higher exposure among HTP users compared to non-users (58% vs. 48% for cigarette advertising; 57% vs. 31% for HTP advertising). At least 1 in 5 HTP users and non-users noticed HTPs and cigarettes advertised on TV, in newspapers/magazines, and on posters/billboards. With a few exceptions, more HTP users noticed HTP advertising than non-users, whereas there were few differences in exposure to cigarette advertising. Non-users had stronger support for TAPS bans than HTP users: POS display bans for HTPs (74% vs. 47%) and cigarettes (65% vs. 49%); bans on cigarette advertising in stores (69% vs. 53%); and price promotions (76% vs. 65%). Conclusions TAPS restrictions are not effective for reducing exposure to HTP and cigarette advertising in Japan. Findings suggest that the public would support a comprehensive TAPS ban.

Objective To assess the attitudes of flavored and unflavored cigarette smokers towards tobacco control policies, including the EU flavors ban and to explore the ban impact on smoking behaviors. Methods The research analysis include data from Wave 1 of the EUREST PLUS-ITC Europe Survey Project in Germany, Greece, Hungary, Poland, Romania, and Spain, and data from other ITC surveys conducted in England and the Netherlands. All cross-sectional data were collected in 2016 among 10,760 adult current smokers. The attitudes towards various tobacco control policies have been compared among menthol, other flavored and unflavored cigarette smokers. The univariate data analysis adjusted to few confounding factors was made with the use of SPSS Complex Samples Package. Results Findings show that menthol smokers are much less likely to support a ban on tobacco additives and flavors than other cigarette smokers but they are more supportive of smoking ban in public places. After the enforcement of the ban, 16% of menthol cigarette smokers and 10% of other flavored cigarette smokers reported the intention to quit smoking. However, the percentage of those menthol and other flavored smokers who declare quitting smoking after the ban implementation varies substantially with countries. Furthermore, almost one of three menthol cigarette smokers (27%) say they will find a way to get menthol tobacco product banned. Conclusions Attitudes of menthol and other flavored cigarettes towards various tobacco control policies differ substantially in the analyzed countries. Therefore, tobacco control and smoking cessation programs should be adapted to country needs. A special attention must be focused on smoking cessation offer addressed to those menthol cigarette smokers who intend to quit smoking after the flavors ban and on preventing the risk of illicit trade in menthol cigarettes.

Objective Before 2018, Japan did not have a national smoke-free law covering indoor public places, workplaces, or public transport as recommended by the WHO FCTC. A national smoking ban was passed in July 2018, to be implemented in stages leading up to the 2020 Olympics; however, the law is still not comprehensive. This study examines baseline levels of smoking in public places and support for smoke-free laws in Japan prior to the 2018 smoke-free law. The results will also be compared to findings from other ITC countries to demonstrate the need for stronger smoke-free legislation. Methods Data are from the International Tobacco Control (ITC) Japan Wave 1 Survey (Feb-Mar 2018), a web survey of adult cigarette smokers, HTP users, dual users, and non-users (total N=4,684). Measures included prevalence of smoking (whether respondents noticed people smoking inside restaurants, bars, and workplaces); smoking rules inside these venues; and support for complete smoking bans in these venues. Results The majority of indoor workplaces in 2018 (52%) had a complete smoking ban; however, restaurants and bars were more likely to have a partial ban or no rules. As a result, smoking prevalence in public places was extremely high overall – even higher than in China, the country with the greatest toll of SHS. Almost half of all workplaces (49%), over half of restaurants (55%) and the majority of bars (83%) had smoking in 2018, although non-users were less likely to be exposed to SHS. Support for complete smoking bans was also high overall (81% for workplaces, 78% for restaurants, and 65% for bars), and was higher among non-users. Conclusions These findings demonstrate the weak impact of partial smoke-free laws in Japan thus far and strong support for a comprehensive national law without exceptions to protect the public from the harms of tobacco smoke.

Objective Prior to December 2012, restaurants in South Korea were required to implement only partial smoking bans. This study documents the changes in Korean smokers’ attitudes towards smoking bans between 2005 and 2010 and explores the effects of anti-smoking advertising as a correlate of support for total smoking bans in public places.Design Longitudinal cohort study of Korean adult smokers.Setting The data were derived from three waves (2005, 2008 and 2010) of the International Tobacco Control (ITC) Korea Survey.Participants The ITC Korea Survey respondents were a probability-based, nationally representative sample of Korean smokers aged 19 and older. The current analysis includes 995 smokers who participated in Wave 1 (2005), 1737 smokers who participated in Wave 2 (2008) and 1560 smokers who participated in Wave 3 (2010).Primary and secondary outcome measures Changes in respondents’ awareness of secondhand smoke (SHS) harm, attitudes towards smoking bans and personal rules for smoking in private homes and/or vehicles were analysed. Correlates of support for smoking bans in public places were examined using generalised estimating equation regression models.Results More than 80% of Korean smokers are aware of the harms of SHS. The proportion of smokers who support smoke-free restaurants or smoke-free bars increased twofold between 2005 and 2010. Smokers who were aware of the dangers of SHS were more likely to support a total smoking ban in workplaces. Noticing anti-smoking advertising or information was not significantly associated with support for a total smoking ban in public places.Conclusions Korean smokers became more supportive of smoking bans in public places between 2005 and 2008. These results show that smokers’ attitudes towards smoking bans can change with the implementation of smoke-free policies, even in a country that has a high prevalence of smokers.

It is well established that intentions to quit smoking is the strongest predictor of future quit attempts. However, most studies on quit intentions have been conducted in high-income countries with very few in low- and middle-income countries particularly in Africa. This is the first population-based study to compare factors associated with quit intentions among smokers in two African countries. Data were from the International Tobacco Control (ITC) Kenya and Zambia Surveys (2012), face-to-face surveys of nationally representative samples of 2291 adult smokers (Kenya = 1103; Zambia = 1188). Multivariate logistic regression analyses were conducted to identify predictors of quit intentions. Most Kenyan (65.1%) and Zambian (69.1%) smokers had quit intentions of which 54.8% planned to quit within the next 6 months. Five factors were significantly associated with quit intentions in both countries: being younger, having tried to quit previously, perceiving that quitting is beneficial to health, worrying about future health consequences of smoking, and being low in nicotine dependence. The predictive strength of these factors did not differ in the two countries. Four additional factors were significant predictors in Zambia only: having a quit attempt lasting six months or more, lower smoking enjoyment, having a negative opinion about smoking, and concern about cigarette expenses. The factors predicting quit intentions were similar to those in other ITC countries including Canada, US, UK, China and Mauritius. These findings highlight the need for stronger tobacco control policies in Kenya and Zambia including increased taxation, greater access to cessation services, and anti-smoking campaigns denormalizing tobacco use.

Tobacco companies are utilizing similar strategies to advertise and promote their products in developing countries as they have used successfully for over 50 years in developed countries. The present study describes how adult smokers, smokeless tobacco users, and non-users of tobacco from the Tobacco Control Project (TCP) India Pilot Survey, conducted in 2006, responded to questions regarding their perceptions and observations of pro-tobacco advertising and promotion and beliefs about tobacco use. Analyses found that 74% (n = 562) of respondents reported seeing some form of pro-tobacco advertising in the last six months, with no differences observed between smokers (74%), smokeless tobacco users (74%), and nonsmokers (73%). More than half of respondents reported seeing pro-tobacco advertising on store windows or inside shops. Overall, this study found that a significant percentage of tobacco users and non-users in India report seeing some form of pro-tobacco advertising and promotion messages. Additional analyses found that smokers were more likely to perceive tobacco use as harmful to their health compared with smokeless tobacco users and non-users (p < 0.01). The findings from this study reiterate the need for stronger legislation and strict enforcement of bans on direct and indirect advertising and promotion of tobacco products in India.

Introduction The current study explores quitting behaviours and use of cessation assistance among adult tobacco users with probable anxiety or depression (PAD) and in six European (EU) Member States (MS). Material and Methods The EUREST-PLUS ITC Wave 1 Europe Survey was conducted with a nationally representative cross-sectional sample of 6,011 adult cigarette smokers from six European Union (EU) Member States (MS) (Germany, Greece, Hungary, Poland, Romania, Spain) in 2016. Results Our study found that one in five smokers sampled from six EU MS had a diagnosis, treatment or positive screen for anxiety or depression, with rates of PAD varying between EU MS. Results of the multivariable logistic regression analysis showed that respondents with PAD were more likely to have made a quit attempt in the last 12 months (AOR 1.75; 95%CI 1.45-2.11), compared to respondents without PAD. Among those respondents with PAD who used support the most frequently reported quit method was prescription-based quit smoking pharmacotherapy (15.4%) followed by e-cigarettes (13.7%) and NRT (11.3%). Person-to-person behavioral support (i.e. local quit services, face-to-face advice from a doctor or other health care professional, telephone or quitline services) was reported significantly more frequently among respondents with PAD compared to those without PAD. Conclusions Given both pharmacological and non-pharmacological quit smoking aids have been shown to be safe, acceptable and effective for people with and without mental illness it is important that their use be promoted among smokers with anxiety and depression alongside behavioral counseling. Our findings support the need for interventions targeting health care professionals in providing smoking cessation assistance among this population of smokers.

Efforts to mitigate the devastation of tobacco-attributable morbidity and mortality in the European Union (EU) consist of its newly adopted Tobacco Products Directive (TPD) along with the first-ever health treaty, the WHO Framework Convention on Tobacco Control (FCTC). The aim of this Horizon 2020 project entitled European Regulatory Science on Tobacco: Policy Implementation to Reduce Lung Disease (EUREST-PLUS) is to monitor and evaluate the impact of the implementation of the TPD across the EU, within the context of WHO FCTC ratification. The EUREST-PLUS ITC cohort study of adult smokers in six EU MS (Germany, Greece, Hungary, Poland, Romania, Spain), uses a pre- vs. post-TPD implementation study design, evaluating the impact of several tobacco control policy provisions, including but not limited to health warning labels, smoke free areas and electronic cigarettes. The study is designed to generate strong inferences about the effectiveness of tobacco control policies, as well as to elucidate the mechanisms and factors by which policy implementation translates to population impact.

Introduction Article 20 of the European Union (EU) Tobacco Products Directive (TPD) sets forth provisions on electronic cigarette (e-cigarette) product regulation, such as child-proof packaging and protection against e-liquid refilling without leakage. The aim of the current study was to examine frequencies and correlates of experiencing undesirable events during e-cigarette use related to e-cigarette product design parameters prior to the implementation of the EU TPD. Material and Methods The EUREST-PLUS ITC Europe Wave 1 survey was conducted with adult cigarette smokers from June to September 2016 across Germany, Greece, Hungary, Poland, Romania, Spain. Results Among our sample of adult cigarette smokers, one in five reported having ever used e-cigarettes. Prevalence of current e-cigarette use (daily or weekly) was very low (1.5%). Major undesirable events, such as battery exploding or catching fire (1.9%) or overheating (11%) were uncommon. Among those reporting at least monthly use and whose usual/current brand has a tank that you fill with liquids, 18.8% experienced spilling during refill and 18.5% experienced e-liquid leaking during use. Nearly one-quarter reported that the e-liquid cap was easy for a child to open. Conclusions In light of the EU TPD establishing standards around e-cigarette design parameters to mitigate undesirable events and risks during e-cigarette use, these findings further support the need for its implementation, as well as for monitoring undesirable events experienced during e-cigarette use once Article 20 is fully implemented.

Background Information dissemination on harmful effects of tobacco has always been a major tool for reducing tobacco consumption in all countries. This paper studies how a change in the Perception of Tobacco Risk (PTR) affects the attitude of smokers and non-smokers towards smoking. First, this paper wants to observe how PTR varies among different types of smokers and non-smokers across different socio-demographic backgrounds. Second, it examines among the cigarette smokers across different socio-demographic groups how changing PTR over the years influences their behavior towards smoking. Methods A panel dataset from the ITC Bangladesh surveys is used for the analysis. Using the panel dataset, a Perception of Tobacco Risk Index (PTRI) is developed for all smokers and non-smokers. OLS and Probit regressions are used on different groups based on income, education, age, residence to assess the effects of knowledge and income on smoking behaviour. Results Results show that among all different types of smokers, quitters have the highest PTRI whereas bidi (cheap local alternative to cigarettes) smokers have the lowest. Among the different socio-demographic groups the higher income, more educated, and those living in urban areas display a higher PTRI than their respective counterparts. However, it is also observed that the change PTRI is bigger among the lower income, less educated and those living in rural areas. Analysis of panel data reveals that the change in PTRI is positively correlated with the probability to quit smoking for most socio-demographic groups. However, increase in PTRI does not significantly affect initiation of smoking and reduces cigarette consumption per day only for the more educated group. Conclusions Results of this paper hold strong policy implications. First, they show that changing PTR holds promising implications for controlling tobacco consumption concerning raising quitting probability. Second, they bring into light, specific socio-demographic groups where policies to change PTR should be targeted.

Background A major objective of FCTC Article 9, which calls for tobacco product regulation, is to eliminate or reduce tobacco industry product design strategies that have been shown to lead smokers to believe that some cigarettes are less harmful than others. However, nearly all of the studies documenting beliefs about harm perceptions have come from high-income countries; little is known whether the same misperceptions about harmfulness are present in low-middle income countries (LMICs)― where 80% of the world's smokers reside. This study measured the level of perceptions of harmfulness of light and menthol cigarettes among smokers from 10 LMICs of the International Tobacco Control (ITC) Project. Methods Cross-sectional analyses of ITC surveys in Bangladesh, Brazil, China, India, Kenya, Malaysia, Mauritius, Mexico, Thailand, and Zambia were conducted using the country's most recent survey wave (ranging from 2011 to 2016). Adult smokers were asked whether each of three design features— (1) light/low tar, (2) filters, and (3) menthol—were less harmful. Results The percentage of smokers with erroneous beliefs was variable but substantial: 'light cigarettes are less harmful': 21% (Mexico) to 66% (China); 'low tar cigarettes are less harmful': 41% (Zambia) to 71% (China); 'menthol cigarettes are less harmful': 11% (Brazil) to 52% (China); 'filters reduce harm': 36% (Mexico) to 82% (China); 'if a cigarette tastes lighter, it is less harmful': 39% (Zambia) to 71% (Kenya). [POH 10 LMICs ITC] Conclusions A substantial proportion of smokers in the 10 LMICs erroneously believe that light, low tar, and menthol cigarettes are less harmful, and that filters reduce harm. This is particularly disturbing in China, where prevalence of industry-induced misconceptions was the highest for 4 of the 5 measures. These findings point to the necessity of Article 9 regulations to restrict/ban product design features that mislead consumers about the harmfulness of tobacco products, particularly in LMICs.

Background The harmful effects of smoking are well documented. Moreover, public knowledge and beliefs about the health risks of smoking and secondhand smoke exposure have increased substantially over the past several decades. Methods The aim of this study is to examine the association between the awareness of the health risks of smoking and secondhand smoke exposure with the desire to quit smoking. The Wave 1 (2016) ITC 6 European Country (6E) Survey within the framework of EUREST-PLUS Project covered both urban and rural areas of the country's 13 geographical regions. The survey sample consisted of 1,000 individuals smokers aged 18 and older in Greece, one of the six ITC 6E countries. Results The majority of Greek smokers agreed that smoking causes lung cancer (95.4%), heart diseases (94.4%), throat cancer (87.9%), bronchitis (87.7%) and mouth cancer (84.8%), however, 51.7% smokers disagreed that smoking could cause blindness, tuberculosis (37.8%), impotence (33.8%), stroke (24%) and heart attacks to non-smokers (27.3%). Chi-square and spearman correlation coefficient were fitted to investigate the association between the awareness of the effects of smoking and the desire to quit. The percentages of the awareness regarding blindness and stroke were less among smokers who reported moderate difficulty to completely quit (p

Background Electronic cigarettes have become an international phenomenon, although few studies have compared e-cigarette use across countries. This paper presents prevalence estimates of self-reported e-cigarette awareness, trial (ever-tried), current use (daily/weekly/monthly), and daily use from 13 countries that vary on the strictness of e-cigarette policies/regulations. Methods Cross-sectional analyses of representative samples of adult (≥18-years) current and former smokers participating in International Tobacco Control Project (ITC) surveys in 13 countries from the most recent ITC survey wave (2013-2017). Countries were categorized into those with no e-cigarette policies (NP), less restrictive policies (LRP), or more restrictive policies (MRP). Results Weighted prevalence estimates of four key measures were computed: 1. Awareness: for NP countries: Zambia (2014): 3%, Bangladesh (2014/15): 7%, China (2013/15): 59%; LRP countries: Netherlands (2017): 92%, Republic of Korea (2016): 94%, United States (US) and England (2016): 99%; MRP countries: Uruguay (2014): 52%, Mexico (2014/15): 61%, Brazil (2016): 73%, Malaysia (2013/2014): 86%, Australia and Canada (2016): 99%. 2. Trial: for NP countries: Zambia (0%), Bangladesh (1%), China (11%); LRP countries: Netherlands (39%), Korea (44%), England (52%). US (58%); MRP countries: Uruguay (7%), Mexico (10%), Malaysia (38%), Australia (45%), Canada (49%). 3. Daily/weekly/monthly use: for NP countries: Zambia and Bangladesh (< 1%); China (1%); LRP countries: Korea (6%), Netherlands, US, England (7%); MRP countries: Uruguay (0%), Brazil (1%), Mexico (2%), Australia and Canada (6%), Malaysia (12%). 4. Daily use: for NP countries: Zambia, Bangladesh, China (all 0%); LRP countries: Korea (3%), Netherlands (3%), US (3%), England (4%); MRP countries: Uruguay and Brazil (0%), Mexico (1%), Canada (2%), Australia (3%), Malaysia (4%). [E-cigarette Trial, Current Use, and Daily Use] Conclusions With minor exceptions (e.g. Australia), awareness, trial, and use of e-cigarettes across the 13 countries generally reflected the de facto environment rather than the statutory environment implied by the law(s). Country income classification and survey year also appear to be strongly associated with use.

Background China's health warnings do not meet the FCTC Article 11 guidelines. They are small (< 35% of the pack) and do not include pictorial images, which research has shown to have greater impact. Four rounds of warnings have been implemented between 1992-2016. This study examines warning impact over 9 years (2006-15), including the third round (April 2012), which increased font size while maintaining overall warning size and replaced the English text with Chinese on the back. Methods Data are from Waves 1-5 (2006-15) of the International Tobacco Control (ITC) China Survey, a cohort survey of 800 adult smokers in each of five cities, adding five rural areas at Wave 5 (2013-15) (total N=8000). GEE logistic regression models tested changes in key indicators of warning impact over time. Results Over 9 years, there has been little change in impact of the Chinese warnings. Indeed, the percentage of smokers who noticed warnings 'often' actually DECREASED from 51% (2006) to 38% (2013-15) ( p < .001), and fewer than one-third of smokers reported cognitions or behaviours related to quitting because of the warnings. The April 2012 revision did not improve any of the warning impact indicators. Warning noticing/salience did not differ between cities and rural areas, but rural smokers were more likely to think 'a lot' about harms of smoking (17% vs 11%, p < .001) and about quitting (14% vs 6%, p < .001) because of the warnings. Conclusions China's text-only warnings continue to be extremely weak. The minor changes in 2012 did not increase warning impact. Global evidence is clear that large pictorial warnings depicting specific harms of cigarettes would greatly enhance warning impact in China, including increasing knowledge and motivation to quit among the 300M Chinese smokers. These benefits would be especially important for the large rural population, where there are fewer other sources of health information.

Background While smoke-free policies in most European countries are established for public places, private areas are mainly not regulated and may represent an important source of second-hand smoke exposure. We aimed to describe and characterise smoking rules in homes and cars of smokers from 6 European countries. Methods We used data from the first wave (2016) of the International Tobacco Control (ITC) 6 European Country Survey, part of the EUREST-PLUS Project, in representative national samples of adult (18+ years) smokers in Germany, Greece, Hungary, Poland, Romania and Spain (1000 in each country). We analysed questions about smoking rules in smokers' homes and cars with children and differentiated among: no rules, partial (allowed in some rooms or under special circumstances) and total ban (smoke-free homes and cars). We computed the prevalence (%) of homes and cars according to the rules, and used Poisson regression models to identify factors associated with total smoking ban. We incorporated weights from the complex sample design. Results In homes, more smokers opted for partial ban rather than for a total ban. The highest and lowest proportions of smoke-free homes were found in Hungary (35.5%) and Spain (13.1%), respectively, while partial ban prevalence ranged from 41.3% (Spain) to 49.9% (Greece). The proportion of smoke-free cars with children was overall higher compared to homes, ranging from 51.8% (Greece) to 67.7% (Germany). Having moderate or high level of education, presence of children, smoking less than 10 cigarettes per day and having previous attempts to quit smoking were positively associated with total smoking ban in homes and cars. Conclusions European smokers tend to opt for partial smoking ban at homes and for total ban in cars with children. Prevalence of smoke-free homes is relatively low and further legal and educational enforcement is needed to promote smoke-free environments.

Background Taxing tobacco is among the most effective measures of tobacco control. However, in a tiered market structure where multiple tiers of taxes co-exist the anticipated impact of tobacco taxes on consumption is complex. This paper investigates changing smoking behavior in lieu of rising prices and changing income. The objective of the paper is to evaluate the effectiveness of change in prices (through taxes) and change in income in a price-tiered cigarette market. Do taxes successfully lead smokers to reduce consumption or simply move to a different price tier? How do income change affect smoking behavior? Methods A panel dataset from the ITC Bangladesh surveys is used for the analysis. The nature of dataset allowed for observing the impact of tax and income change on the smoking behavior of the same individual over a length of three years. Probit regressions are used to identify the effects of changes in prices and changes in income along with other control variables. Results Transition matrices show significant movement of smokers across price tiers from one wave to another. Regression results show when smokers face higher cigarette prices, their probability to down-trade increases and probability to up-trade decreases. Interestingly higher taxes do not increase the probability to quit. Also, higher income raises the probability to up-trade and decreases the probability to quit smoking. Conclusions It is evident from the results that a price-tiered market provides smokers more flexibility to accommodate their smoking behavior when faced with price and income change. Therefore, tiered structure of the tax system should be replaced with uniform taxes so that all price tiers are taxed with equal aggression. Results also reveal the need for overall cigarette taxes to be raised to an extent so that it off-sets any positive effects of income growth.

Background Menthol and other flavorings are appealing to young people. They mask the adverse effects of cigarette smoke, such as throat irritation, and are marketed as less harmful to appeal to health-concerned smokers. In March 2012, Brazil banned all flavors in tobacco products, including menthol, but the ban has not been implemented due to industry legal challenges. This is the first study in Brazil to examine menthol use and beliefs about menthols (particularly harm perceptions). Such research can increase an understanding of menthol use to inform/support regulatory action in Brazil and other countries. Methods Data were from Wave 3 (2016-17) of the International Tobacco Control (ITC) Brazil Survey, a cohort survey of adult smokers and non-smokers in Rio de Janeiro, São Paulo, and Porto Alegre. This study analyzed responses from 1216 smokers on prevalence and predictors of menthol use, beliefs about harmfulness, and support for banning additives. Results In 2016-17, 7.8% of smokers with a regular cigarette brand reported that they smoked menthols (lowest of 10 ITC LMICs). 12.5% of smokers erroneously believed that menthol cigarettes are less harmful than regular cigarettes (lowest of 7 ITC middle-income countries); 33.4% believed menthols are smoother on the throat and chest (lowest of 4 LMICs). 59.6% of smokers support a complete ban on all additives including flavorings (3rd highest among 14 ITC countries). Conclusions These findings support Brazil's effort to ban all additives including menthol: menthol prevalence is comparatively low, erroneous beliefs that menthols are less harmful is low, and support for an additive ban is high. Brazilian media reporting of the risks of additives in the context of the tobacco industry injunction may have raised public awareness of the harms of additives and support for the ban. Also, the 2014 ban on advertising at points of sale may have reduced exposure to marketing of menthols.

Background In India, it is important to understand the factors that promote intention to quit as quitting is rather uncommon. Data from International Tobacco Control Policy (TCP) Project conducted in four states (Maharashtra, Bihar, Madhya Pradesh and West Bengal) were used to investigate the factors associated with intention to quit tobacco. Methods Data from Wave 1 (Aug 2010-Dec 2011) comprising 8,051 tobacco users and Wave 2 (Aug 2012-Dec 2013) comprising 7,401 users were analysed. Respondents reporting planning to quit using tobacco in the next month, in the next six months, or sometime in the future, were categorized as having an intention to quit. Bivariate analysis and multivariable logistic regression was used to study the relationship between intention to quit and factors associated with intention to quit among tobacco users. All analyses were performed using SPSS V.20.0. Results Intention to quit decreased from 19.6% in Wave 1 to 13.5% in Wave 2. In both waves, education, advice from doctors to quit and exposure to warning messages on tobacco packages were associated with intention to quit tobacco. Exposure to anti-tobacco messages on public transportation vehicles (OR=2.13, CI=1.49-3.08), in restaurants (OR=1.63, CI=1.11-2.40), in bars (OR=1.81, CI=1.07-3.06) and at workplaces (OR=1.73, CI=1.23-2.44) were associated with intention to quit in Wave 1. However, these relationships were not significant in Wave 2. Conclusions Perceptions of individuals leading to intention to quit are rapidly changing over the years. Future tobacco control efforts could emphasize on making warnings more effective that depict the harm of tobacco, taking into consideration, education of individuals. Also, involving doctors to advise patients to quit might increase motivation to quit tobacco use.
