Introduction: This study examined whether smokers' harm perceptions of nicotine replacement therapy (NRT) and nicotine vaping products (NVPs) relative to cigarettes predicted their subsequent use as smoking cessation aids during their last quit attempt (LQA)., Aims and Methods: We analyzed data from 1,315 current daily smokers (10+ cigarettes per day) who were recruited at Wave 1 (2016), and who reported making a quit attempt by Wave 2 (2018) of the International Tobacco Control Four Country Smoking and Vaping Surveys in Australia, Canada, England, and the United States. We used multinomial logistic regression models to examine prospective associations between harm perceptions of (a) NRT and (b) NVPs and their use at LQA, controlling for socio-demographic and other potential confounders., Results: Smokers who perceive that (a) NRT and (b) NVPs are much less harmful than cigarettes were more likely to subsequently use the respective product as an aid than using no aid or other aids during LQA (adjusted relative risk ratio [aRRR] = 3.79, 95%CI = 2.16-6.66; and aRRR = 2.11, 95%CI = 1.29-3.45, respectively) compared to smokers who perceive these products as equally or more harmful. Additionally, those who perceive NVPs as much less harmful than cigarettes were less likely to use NRT as a quit aid (aRRR = 0.34, 95%CI = 0.20-0.60). No country variations for these associations were found., Conclusions: This study found that smokers' perceptions of the harmfulness of (a) NRT and (b) NVPs relative to cigarettes predicted the respective product use when trying to quit smoking. Corrective education targeting misperceptions of nicotine products' relative harmfulness may facilitate their use for smoking cessation., Implications: Nicotine replacement therapy and nicotine vaping products are two commonly used smoking cessation aids. This study demonstrates that misperceptions of the harms of nicotine products relative to cigarettes influence their use for smoking cessation. Believing that nicotine vaping products are much less harmful than cigarette smoking may lead some smokers to prefer these products over nicotine replacement therapy to aid smoking cessation. Education targeting misperceptions of nicotine products' harmfulness relative to cigarettes may enable smokers to make informed choices about which are appropriate to aid smoking cessation., (© The Author(s) 2022.

Objectives: Regulation of nicotine vaping products (NVPs) varies between countries, impacting the availability and use of these products. This study updated the analyses of O'Connor et al on types of NVPs used and examined changes in NVP features used over 18 months in four countries with differing regulatory environments., Design: Data are from 4734 adult current vapers in Australia, Canada, England and the USA from Waves 1 (2016) and 2 (2018) of the International Tobacco Control Four Country Smoking and Vaping Survey. NVP characteristics included device description, adjustable voltage, nicotine content and tank size. Longitudinal analyses (n=1058) assessed movement towards or away from more complex/modifiable NVPs. A logistic regression was used to examine factors associated with changes in device description from 2016 to 2018., Results: Like 2016, box-tanks were the most popular NVP (37.3%) in all four countries in 2018. Over 80% of vapers continued using the same NVP and nicotine content between waves, though movement tended towards more complex/modifiable devices (14.4% of vapers). Box-tank users, exclusive daily vapers and older vapers were most likely to continue using the same device description. Certain NVPs and features differed by country, such as higher nicotine contents in the USA (11.5% use 21+ mg/mL) and greater device stability over time in Australia (90.8% stability)., Conclusions: Most vapers continued using the same vaping device and features over 18 months. Differences in NVP types and features were observed between countries, suggesting that differing NVP regulations affect consumer choices regarding the type of vaping device to use., Competing Interests: Competing interests: AM is a UK National Institute for Health Research (NIHR) Senior Investigator.

Background: Past research indicates that smokers with a large number of smoking friends within their social network are less interested in quitting, less likely to attempt to quit, and less likely to successfully quit. The extent to which a pro-smoking social network may increase relapse risk among ex-smokers is unclear. This study investigated among ex-smokers whether the number of close friends who smoke and changes in this number influence relapse risk., Methods: The study was a prospective cohort study of 551 adults who participated in the Australian and UK arms of the International Tobacco Control (ITC) project and were ex-smokers at wave 9 (2013) and followed up to wave 10 (2014). Logistic models regressed smoking relapse at follow-up on the baseline number of their five closest friends who smoked and changes in this number over time., Results: Ex-smokers who reported having 4 or 5 smokers among their five closest friends were more likely to relapse than those who had no smokers among their five closest friends (adjusted odds ratio [AOR] = 4.86, 95% confidence interval [CI] = 1.48-15.99, p = .009). Ex-smokers who gained smoking friends over time, but not those who lost smoking friends, were also more likely to relapse compared to those with the same number of smoking friends over time (AOR = 4.52, 95% CI = 2.15-9.52, p < .001; AOR = 1.08, 95% CI = 0.49-2.36, p = .848, respectively)., Conclusions: This study demonstrated that relapse risk was elevated among ex-smokers who had more smokers among their close friends and also among those where the number of smokers in their social network increased over time., (Copyright © 2022 Elsevier Inc.

Importance: The prevalence of electronic nicotine delivery systems (ENDS) use, including e-cigarettes, among US young adults (YAs) has raised questions about how these products may affect future tobacco and nicotine use among YAs. Given this prevalence and that young adulthood is a critical period for the establishment of tobacco and nicotine use, it is important to consider the association between ENDS use and cigarette smoking specifically in this age group., Objective: To examine whether ENDS use frequency or intensity is associated with changes in cigarette smoking among US YA ever smokers during 1 year., Design, Setting, and Participants: This cohort study used 3 waves of data (2013-2014, 2014-2015, and 2015-2016) from the Population Assessment of Tobacco and Health (PATH) Study, an ongoing longitudinal cohort study of adults and youth. Unweighted 1:6 propensity score matching was used to match participants on wave 1 risk factors for ENDS use at wave 2. The changes in smoking between wave 2 and wave 3 were assessed using the matched sample. In total, 1096 ENDS-naive, ever cigarette-smoking YAs (18-24 years of age) at wave 1 who participated in wave 2 and wave 3 and who had complete data in the PATH Study were included in the analyses, which were conducted from August 2018 to October 2019., Exposures: Never ENDS use (n = 987), any previous 30-day ENDS use (n = 109), 1 to 5 days of ENDS use in the previous 30 days (n = 75), and 6 or more days ENDS use in the previous 30 days at wave 2 (n = 34)., Main Outcomes and Measures: The analytic sample was selected using multiple variables based on peer-reviewed literature supporting associations with ENDS use. The main outcomes-changes in cigarette smoking behavior between wave 2 and wave 3-were defined using 2 measures: (1) change in smoking frequency, defined as the number of smoking days in the previous 30 days at wave 3 vs wave 2, and (2) change in smoking intensity, defined as the number smoking days in the previous 30 days multiplied by the mean number of cigarettes consumed on smoking days at wave 3 vs wave 2., Results: The present cohort analyses included 1096 YA ever smokers who were ENDS naive at wave 1. The majority of the sample were women (609 [55.6%]) and White individuals (698 [63.7%]), and the mean (SD) age was 21.4 (1.9) years. In wave 1, 161 YAs (14.7%) were daily smokers in the previous 30 days. After propensity score matching, no statistically significant associations were observed between any definition of wave 2 ENDS use and changes in either the frequency or intensity of smoking at wave 3., Conclusions and Relevance: In this cohort study of US YA ever smokers, ENDS use was not associated with either decreased or increased cigarette smoking during a 1-year period. However, it is possible that the rapidly evolving marketplace of vaping products may lead to different trajectories of YA cigarette and ENDS use in the future.

Background: More smokers report using e-cigarettes to help them quit than FDA-approved pharmacotherapy., Objective: To assess the association of e-cigarettes with future abstinence from cigarette and tobacco use., Design: Cohort study of US sample, with annual follow-up., Participants: US adult (ages 18+) daily cigarette smokers identified at Wave 1 (W1; 2013-14) of the PATH Study, who reported a quit attempt before W2 and completed W3 (n = 2443)., Exposures: Use of e-cigarettes, pharmacotherapy (including nicotine replacement therapy), or no product for last quit attempt (LQA), and current daily e-cigarette use at W2., Analysis: Propensity score matching (PSM) of groups using different methods to quit., Outcome Measures: 12+ months abstinence at W3 from cigarettes and from all tobacco (including e-cigarettes). 30+ days abstinence at W3 was a secondary outcome., Results: Among daily smokers with an LQA, 23.5% used e-cigarettes, 19.3% used pharmacotherapy only (including NRT) and 57.2% used no product. Cigarette abstinence for 12+ months at W3 was ~10% in each group. Half of the cigarette abstainers in the e-cigarette group were using e-cigarettes at W3. Different methods to help quitting had statistically comparable 12+ month cigarette abstinence at W3 (e-cigarettes vs no product: Risk Difference (RD) = 0.01, 95% CI: -0.04 to 0.06; e-cigarettes vs pharmacotherapy: RD = 0.02, 95% CI:-0.04 to 0.09). Likewise, daily e-cigarette users at W2 did not show a cessation benefit over comparable no-e-cigarette users and this finding was robust to sensitivity analyses. Abstinence for 30+ days at W3 was also similar across products., Limitations: The frequency of e-cigarette use during the LQA was not assessed, nor was it possible to assess continuous abstinence from the LQA., Conclusion: Among US daily smokers who quit cigarettes in 2014-15, use of e-cigarettes in that attempt compared to approved cessation aids or no products showed similar abstinence rates 1-2 years later., Competing Interests: KMC has received payment as a consultant to Pfizer, Inc., for service on an external advisory panel to assess ways to improve smoking cessation delivery in health care settings.

Objective: This study examines sociodemographic and tobacco use correlates of reuptake and relapse to tobacco use across a variety of tobacco products (cigarettes, electronic nicotine delivery systems, cigars, hookah and smokeless tobacco) among the US population., Design: Data were drawn from the first three waves (2013-2016) of the Population Assessment of Tobacco and Health Study, a nationally representative, longitudinal cohort study of US youth (ages 12-17) and adults (ages 18+). Reuptake (past 30-day use among previous tobacco users) and relapse (current use among former established users; adults only) were examined among previous users of at least one type of tobacco product at Wave 1 (W1) or Wave 2 (W2) (n=19 120 adults, n=3039 youth). Generalised estimating equations were used to evaluate the association between demographic and tobacco use characteristics at baseline, with reuptake/relapse at follow-up, over two 1-year periods (W1-W2 and W2-Wave 3)., Results: Any tobacco product reuptake occurred in 7.8% of adult previous users and 30.3% of youth previous users. Correlates of any tobacco reuptake included being male, non-Hispanic black and bisexual in adults, but race and sexual orientation were not consistent findings in youth. Among recent former users, relapse rates were greater (32.9%). Shorter time since last use and greater levels of tobacco dependence showed the strongest association with any tobacco relapse., Discussion: Continued clinical and public health efforts to provide adults with tools to cope with tobacco dependence symptoms, especially within the first year or two after quitting, could help prevent relapse., Competing Interests: Competing interests: WMC reports long-term stock holdings in General Electric Company, 3M Company, and Pfizer Incorporated, unrelated to this manuscript.

Objective: The goal of this study is to examine the cross-sectional prevalence of use and 3-year longitudinal pathways of cigar use in US youth (12-17 years), young adults (18-24 years), and adults 25+ (25 years or older)., Design: Data were drawn from the first three waves (2013-2016) of the Population Assessment of Tobacco and Health Study, a nationally representative, longitudinal cohort study of US youth and adults. Respondents with data at all three waves (youth, n=11 046; young adults, n=6478; adults 25+, n=17 188) were included in longitudinal analyses., Results: Weighted cross-sectional prevalence of past 30-day (P30D) use was stable for adults 25+ (~6%), but decreased in youth (Wave 1 (W1) to Wave 3 (W3)=2.5% to 1.2%) and young adults (W1 to W3=15.7% to 14.0%). Among W1 P30D cigar users, over 50% discontinued cigar use (irrespective of other tobacco use) by Wave 2 (W2) or W3. Across age groups, over 70% of W1 P30D cigar users also indicated P30D use of another tobacco product, predominantly cigar polytobacco use with cigarettes. Discontinuing all tobacco use by W2 or W3 was greater in adult exclusive P30D cigar users compared with polytobacco cigar users., Conclusions: Although the majority of P30D cigar users discontinued use by W3, adult polytobacco users of cigars were less likely to discontinue all tobacco use than were exclusive cigar users. Tracking patterns of cigar use will allow further assessment of the population health impact of cigars., Competing Interests: Competing interests: WMC reports long-term stock holdings in General Electric Company, 3M Company, and Pfizer Incorporated, unrelated to this manuscript.

Objectives: In this study, we identified differences in cessation, nicotine dependence, and quit attempts between smokers using non-menthol cigarettes and smokers using menthol cigarettes differing in menthol delivery method (eg, menthol in the tobacco only, crushable capsules only or both). Methods: We analyzed data from the Population Assessment of Tobacco and Health Study, Waves 1 and 2 (W1 and W2), to determine associations of delivery method of menthol with cessation, nicotine dependence, and quit attempts among current adult cigarette smokers. Results: Nearly 40% of US smokers reported using a mentholated cigarette product with most using a product mentholated in the tobacco only. Smokers included in this analysis had a moderate to low heaviness of smoking index score. The lowest average score was among those using products mentholated in a filter capsule only (1.3, SE = .10), and the highest among those using non-mentholated products (2.4, SE = .03). About 12% of smokers quit between W1 and W2. Cessation, nicotine dependence, and quit attempts at W2 were not associated with delivery method of menthol at W1. Conclusions: Method of menthol delivery did not impact cessation, nicotine dependence, and quit attempts.

Background and Aims: Debate exists about whether health professionals (HPs) should advise smokers to use nicotine vaping products (NVPs) to quit smoking. The objectives were to examine in four countries: (1) the prevalence of HP discussions and recommendations to use an NVP; (2) who initiated NVP discussions; (3) the type of HP advice received about NVPs; and (4) smoker's characteristics related to receiving advice about NVPs., Design: Cross-sectional study using multivariable logistic regression analyses on weighted data from the 2016 ITC Four Country Smoking and Vaping Survey (ITC 4CV1)., Setting: Four countries with varying regulations governing the sale and marketing of NVPs: 'most restrictive' (Australia), 'restrictive' (Canada) or 'less restrictive' (England and United States)., Participants: A total of 6615 adult smokers who reported having visited an HP in the last year (drawn from the total sample of 12 294 4CV1 respondents, of whom 9398 reported smoking cigarettes daily or weekly). Respondents were from the United States (n = 1518), England (n = 2116), Australia (n = 1046), and Canada (n = 1935)., Measurements: Participants' survey responses indicated if they were current daily or weekly smokers and had visited an HP in the past year. Among those participants, further questions asked participants to report (1) whether NVPs were discussed, (2) who raised the topic, (3) advice received on use of NVPs and (4) advice received on quitting smoking., Findings: Among the 6615 smokers who visited an HP in the last year, 6.8% reported discussing NVPs with an HP and 2.1% of smokers were encouraged to use an NVP (36.1% of those who had a discussion). Compared with Australia (4.3%), discussing NVPs with an HP was more likely in the United States [8.8%, odds ratio (OR) = 2.15, 95% confidence interval (CI) = 1.41-3.29] and Canada (7.8%, OR = 1.87, 95% CI = 1.26-2.78). Smokers in Australia were less likely to discuss NVPs than smokers in England (6.2%), although this was not statistically significant (OR = 1.47, 95% CI = 0.98-2.20). Overall, the prevalence of HPs recommending NVPs was three times more likely in the United States than in Australia (OR = 3.07, 95% CI = 1.45-6.47), and twice as likely in Canada (OR = 2.28, 95% CI = 1.06-4.87) than in Australia. Australia and England did not differ (OR = 1.76, 95% CI = 0.83-3.74). Just over half (54%) of respondents brought up NVPs themselves; there were no significant differences among countries., Conclusions: Discussions in Australia, Canada, England, and the United States between smokers and health professionals about nicotine vaping products appear to be infrequent, regardless of the regulatory environment. A low percentage of health professionals recommended vaping products. This was particularly evident in Australia, which has the most restrictive regulatory environment of the four countries studied., (© 2018 Society for the Study of Addiction.)

Objective We assessed whether in-depth messaging delivered via a smoking cessation quitline results in participants: (1) speaking to their physician, or (2) insurance company regarding lung cancer screening (LCS). MethodsEligible participants lived in New York State and met the United States Preventive Services Task Force eligibility criteria for LCS (N = 1000). A randomized trial was conducted among New York State Smokers' Quitline participants to assess the impact of a brochure containing information on risks, benefits, and costs associated with LCS (control group) versus the brochure supplemented with phone-based in-depth messaging (treatment group). ResultsAfter a 4-month telephone survey (N = 431), associations between the study groups were examined for: (1) speaking with a physician regarding LCS, and (2) speaking with an insurance company about LCS coverage. Multivariate logistic regression models adjusted for demographics, insurance status, emphysema/COPD, and past 30-day cigarette use found no significant associations. However, sensitivity analyses among control participants found significant associations, including for speaking with a physician (p < .05) by receipt of the study brochure. Analyses repeated in the treatment group also had statistically significant findings emerge, including for speaking with insurance company (p < .05). ConclusionsThe educational brochure may be an effective and low-cost way to deliver information about LCS.

Context: Cancer patients' continued tobacco use results in poorer therapeutic outcomes including decreased quality of life and survival., Objective: To assess reach and impact of a free, opt-out, telephone-based tobacco cessation program for thoracic cancer center patients., Design: Observational study., Setting: Comprehensive Cancer Center in Western New York., Participants: Current or recent (within past 30 days) tobacco-using thoracic cancer center patients referred to a tobacco cessation support service between October 2010 and October 2012 at a Comprehensive Cancer Center (n = 942/1313 referrals were eligible for cessation support)., Intervention: A free, opt-out, telephone-based cessation service that was implemented as standard of care. Cessation specialists had patient-guided conversations that assessed readiness to quit; methods used in the past provided cessation strategies and worked to set up a quit date. There was an average of 35.9 days between referral and first contact., Main Outcome Measures: Program reach (referral and participation rates) and impact (as self-reported cessation outcomes measured twice after referral)., Results: Of 942 patients, 730 (77.5%) referred to and called by a tobacco cessation service participated in at least 1 cessation support call, of which 440 of 730 (60.3%) were called for follow-up and 89.5% (394/440) participated. In total, 20.2% (69/342) of current smokers at referral reported at least 7-day abstinence at follow-up. Among current smokers at referral and first contact, being married (odds ratio [OR] = 2.05; 95% confidence interval [CI], 1.01-4.18) and having a lower Eastern Cooperative Oncology Group (ECOG) performance score (OR = 4.05; 95% CI, 1.58-10.39) were associated with quitting at follow-up, after controlling for demographic, clinical, and health behavior characteristics., Conclusions: Our results demonstrate that 78% of thoracic cancer center patients, if contacted, participated at least once in this cessation support service; for current smokers at referral and first contact, being married and having a lower ECOG performance score were associated with self-reported quitting at follow-up. Other organizations may find our results useful while implementing a systematic way to identify tobacco-using patients as part of routine care and to improve available cessation support services.

Background: Cigarette pack health warning labels can elicit negative emotions among smokers, yet little is known about how these negative emotions influence behavior change., Objective: Guided by psychological theories emphasizing the role of emotions on risk concern and behavior change, we investigated whether smokers who reported stronger negative emotional responses when viewing warnings reported stronger responses to warnings in daily life and were more likely to try to quit at follow-up., Methods: We analyzed data from 5439 adult smokers from Australia, Canada, Mexico, and the US, who were surveyed every four months from September 2012 to September 2014. Participants were shown warnings already implemented on packs in their country and reported negative emotional responses (i.e., fear, disgust, worry), which were averaged (range = 1 to 9). Country-stratified logistic and linear generalized estimating equations were used to analyze the effect of negative emotional responses on self-reported responses to warnings in daily life (i.e., attention, risk concern, avoidance of warnings, forgoing planned cigarettes) and quit attempts at follow-up. Models were adjusted for socio-demographic and smoking-related characteristics, survey wave, and the number of prior surveys answered., Results: Smokers who reported stronger negative emotions were more likely to make quit attempts at follow-up (Adjusted ORs ranged from 1.09 [95% CI 1.04 to 1.14] to 1.17 [95% CI 1.12 to 1.23]; p < .001) than those who reported lower negative emotions. This relationship was mediated through attention to warnings and behavioral responses to warnings. There was no significant interaction of negative emotions with self-efficacy or nicotine dependence., Conclusion: Negative emotions elicited by warnings encourage behavior change, promoting attention to warnings and behavioral responses that positively predict quit attempts., (Copyright © 2017 The Authors.

Background: Electronic cigarette (e-cigarette) use in the USA is increasing. As such, it is critical to understand who uses e-cigarettes, how e-cigarettes are used and what types of products are prevalent. This study assesses patterns of current e-cigarette use among daily and non-daily adult users in the 2013-2014 Population Assessment of Tobacco and Health (PATH) Study., Methods: We examined the proportion of current adult e-cigarette users (n=3642) reporting infrequent use (use on 'some days' and use on 0-2 of the past 30 days), moderate use (use on 'some days' and use on >2 of the past 30 days) and daily use. We examined demographic characteristics, use of other tobacco products and e-cigarette product characteristics overall and by use category. Adjusted prevalence ratios (aPRs) were calculated using Poisson regression to assess correlates of daily e-cigarette use., Results: Among the 5.5% of adult current e-cigarette users in the PATH Study, 42.2% reported infrequent use, 36.5% reported moderate use and 21.3% reported daily use. Cigarette smokers who quit in the past year were more likely to report daily e-cigarette use, compared with current smokers (aPR=3.21, 95% CI=2.75 to 3.76). Those who reported using rechargeable or refillable devices were more likely to report daily use compared with those who did not use these devices (aPR=1.95, 95% CI=1.44 to 2.65 and aPR=2.10, 95% CI=1.75 to 2.52, respectively)., Conclusions: The majority of e-cigarette users in this study reported less than daily use. Compared with non-daily use, daily use was associated with being a former smoker; however, cross-sectional data limits our ability to establish the temporality or directionality of such associations., Competing Interests: Competing interests: MLG received research grant from Pfizer and served as a member of advisory board to J&J, manufacturers of smoking cessation medications.

Background: Non-menthol characterising flavours (eg, fruit, candy) are banned in cigarettes, yet are still permitted in non-cigarette tobacco (NCT) products. This study examined associations between first use and current use of flavoured tobacco products, and current flavoured tobacco use and quit behaviours., Methods: A nationally representative, telephone-based survey completed in 2012 by 1443 US adult tobacco users asked about use of 9 tobacco products: cigarettes, e-cigarettes, cigars, cigarillos, little filtered cigars, pipes, hookah, smokeless tobacco and snus. Ever users reported first use of flavoured products, while current users also reported current flavoured product use. Current users reported quit attempts made in the past year. Data were weighted to reflect the US adult tobacco user population. Logistic regression models were used to examine associations between first/current flavour use and quit behaviours., Results: Over 70% of respondents reported first use of a flavoured tobacco product, while 54% reported current use of at least one flavoured product. Odds of current flavoured product use were greater among those who reported first use of a flavoured product (OR 14.82, 95% CI 9.96 to 22.06). First use of a flavoured product was associated with being a current tobacco user (OR 1.55, 95% CI 1.08 to 2.22). Compared to single product users, polytobacco users exhibited greater odds of reporting current use of flavoured products (OR 2.09, 95% CI 1.47 to 2.97). Forty-four percent of current tobacco users reported a past-year quit attempt. Adjusted analyses among current NCT users of at least one flavoured tobacco product showed reduced odds of reporting a quit attempt., Conclusions: First use of a flavoured tobacco product was associated with current flavoured tobacco use and polytobacco use. Users of only flavoured NCT products exhibited reduced odds of reporting a quit attempt. Findings from this study reinforce the importance of flavoured product availability in the USA, which may have significant implications for efforts to reduce tobacco initiation and use at a population level. The relationship between characterising flavours and quit behaviours merits further exploration in longitudinal, population-based samples., (Published by the BMJ Publishing Group Limited.

This study evaluated the relationship between interpersonal communication about cigarette health warning labels (HWLs), psychological responses to HWLs, and smoking cessation attempts. Data were analyzed from online consumer panels of adult smokers in Australia, Canada and Mexico, during implementation of new pictorial health warning labels (HWLs) on cigarette packs. Approximately 1000 adult smokers were surveyed in each country every four months (September 2012, January 2013, May 2013, September 2013, January 2014). Only smokers followed for at least two waves were included in the analytic sample. Participants reported the frequency of talking about HWLs in the last month (in general, with family members, and with friends). For each country, poisson generalized estimating equation (GEE) models were estimated to assess the bivariate and adjusted correlates of talking about HWLs. Logistic GEE models regressed having attempted to quit by the subsequent wave on HWL talk, sociodemographics and psychological responses to HWLs. The frequency of HWL talk gradually decreased in Canada (48%-36%) after new HWLs were implemented; an increase (30%-58%) in Australia corresponded with implementation of new HWLs, after which talking stabilized; and the frequency of HWL talk in Mexico was stable over time, where new HWLs are implemented every six months. Talk about HWLs was an independent predictor of subsequent quit attempts in Canada (AOR = 1.50; 95% CI = 1.11-2.02), Australia (AOR = 1.41; 95% CI = 1.05-1.89), and Mexico (AOR = 1.53; 95% CI = 1.11-2.10), as was cognitive responses to HWLs (Australia AOR = 1.66; 95% CI = 1.22-2.24; Canada AOR = 1.56; 95% CI = 1.15-2.11; Mexico AOR = 1.30; 95% CI = 0.91-1.85). No interaction between talk and cognitive reactions to HWLs were found. These results suggest that interpersonal communication about HWLs influences smoking cessation attempts independent of other established predictors of smoking cessation, including cessation-related HWL responses. Future research should determine ways to catalyze interpersonal communication about HWLs and thereby potentiate HWL effects., (Copyright © 2015 The Authors. Published by Elsevier Ltd..

Introduction: Validated methods to evaluate consumer responses to modified risk tobacco products (MRTPs) are needed. Guided by existing literature that demonstrates a relationship between normative beliefs and future intentions to use tobacco the current research sought to (1) develop a measure of normative beliefs about smokeless tobacco (ST) and establish the underlying factor structure, (2) evaluate the structure with confirmatory factor analysis utilizing an independent sample of youth, and (3) establish the measure's concurrent validity., Methods: Respondents (smokers and nonsmokers aged 15-65; N = 2991) completed a web-based survey that included demographic characteristics, tobacco use history and dependence, and a measure of attitudes about ST adapted from the Normative Beliefs about Smoking scale. A second sample of youth (aged 14-17; N = 305) completed a similar questionnaire., Results: Exploratory factor analysis produced the anticipated three-factor solution and accounted for nearly three-quarters of the variance in the data reflecting (1) perceived prevalence of ST use, (2) popularity of ST among successful/elite, and (3) approval of ST use by parents/peers. Confirmatory factor analysis with data from the youth sample demonstrated good model fit. Logistic regression demonstrated that the scales effectively discriminate between ST users and nonusers and are associated with interest in trying snus., Conclusions: Assessment of MRTPs for regulatory purposes, which allows messages of reduced risk, should include measurement of social norms. Furthermore, surveillance efforts that track use of new MRTPs should include measures of social norms to determine how norms change with prevalence of use., (© The Author 2015.

Objective: Evaluate the second flight of the U.S. Tips From Former Smokers (Tips) campaign., Method: Data were analyzed from an online consumer panel of U.S. adult smokers before (n = 1,404) and after (n = 1,401) the 2013 Tips campaign launch. Generalized estimating equation models assessed whether the Tips advertisement recall was associated with knowledge about smoking-related risks in the Tips advertisements, awareness and use of a toll-free quitline and cessation websites, and quit attempts., Results: Seventy-one percent of participants at Wave 2 reported that they recalled seeing at least one Tips advertisement. Smokers who recalled seeing a Tips advertisement were more likely to (a) show increases over baseline in knowledge of health risks such as amputation: 65% versus 34%, p < .001; blindness: 27% versus 12%, p < .001; and (b) to be aware of a quitline (41% vs. 30%, p < .001) and cessation website (28% vs. 20%, p < .001). Recall of Tips advertisements was also associated with greater likelihood of reporting having visited cessation websites (odds ratio [OR] = 1.62, 95% confidence interval [CI] = 1.27-2.06), having called a quitline (OR = 2.28, 95% CI = 1.61-3.24), and having made a quit attempt (OR = 1.18, 95% CI = 1.00-1.39), although these results were only statistically significant in the unadjusted models., Conclusions: The 2013 Tips campaign was successful in increasing knowledge of health risks and awareness of tobacco cessation resources., (© 2015 Society for Public Health Education.)

Introduction: This study characterizes tobacco cessation patterns and the association of cessation with survival among lung cancer patients at Roswell Park Cancer Institute: an NCI Designated Comprehensive Cancer Center., Methods: Lung cancer patients presenting at this institution were screened with a standardized tobacco assessment, and those who had used tobacco within the past 30 days were automatically referred to a telephone-based cessation service. Demographic, clinical information, and self-reported tobacco use at last contact were obtained via electronic medical records and the Roswell Park Cancer Institute tumor registry for all lung cancer patients referred to the service between October 2010 and October 2012. Descriptive statistics and Cox proportional hazards models were used to assess whether tobacco cessation and other factors were associated with lung cancer survival through May 2014., Results: Calls were attempted to 313 of 388 lung cancer patients referred to the cessation service. Eighty percent of patients (250 of 313) were successfully contacted and participated in at least one telephone-based cessation call; 40.8% (102 of 250) of persons contacted reported having quit at the last contact. After controlling for age, pack year history, sex, Eastern Cooperative Oncology Group performance status, time between diagnosis and last contact, tumor histology, and clinical stage, a statistically significant increase in survival was associated with quitting compared with continued tobacco use at last contact (HR = 1.79; 95% confidence interval: 1.14-2.82) with a median 9 month improvement in overall survival., Conclusions: Tobacco cessation among lung cancer patients after diagnosis may increase overall survival.

Background: Canada is the first country in the world to require cigarette manufacturers to enclose package inserts to supplement the exterior pictorial health warning label (HWL). In June 2012, Canada implemented new HWL package inserts that include cessation tips accompanied by a pictorial image. This study aims to assess the extent to which adult smokers report reading the newly mandated HWL inserts and to see whether reading them is associated with making a quit attempt., Methods: Data were analyzed from an online consumer panel of Canadian adult smokers, aged 18-64 years. Five waves of data were collected between September 2012 and January 2014, separated by 4-months intervals (n = 1,000 at each wave). Logistic generalized estimating equation (GEE) models were estimated to assess correlates of reading inserts and whether doing so is associated with making a quit attempt by the subsequent wave., Results: At each wave, between 26% and 31% of the sample reported having read HWL package inserts at least once in the prior month. Smokers who read them were more likely to be younger, female, have higher income, intend to quit, have recently tried to quit, and thought more frequently about health risks because of warning labels. In models that adjusted for these and other potential confounders, smokers who read the inserts a few times or more in the past month were more likely to make a quit attempt at the subsequent wave compared to smokers who did not read the inserts., Conclusions: HWL package inserts with cessation-related tips and messages appear to increase quit attempts made by smokers., (© The Author 2014.

Objectives: This study explored the relationship between product trials and consumer demand for alternative nicotine products (ANP)., Methods: An experimental auction was conducted with 258 adult smokers, wherein participants were randomly assigned to one of four experimental conditions. The participants received the opportunity to try, but did not have to accept, one of three relatively novel ST products (i.e., snus, dissolvable tobacco, or medicinal nicotine), or they were placed into a control group (i.e., no trial). All the participants then bid on all three of these products, as well as on cigarettes. We assessed interest in using ANP based on both trial of the product and bids placed for the products in the experimental auction., Results: Fewer smokers were willing to try snus (44%) than dissolvable tobacco (64%) or medicine nicotine (68%). For snus, we find modest evidence suggesting that willingness to try is associated with greater demand for the product. For dissolvable tobacco or medicinal nicotine, we find no evidence that those who accept the product trial have higher demand for the product., Conclusions: Free trials of a novel ANP were not strongly associated with product demand, as assessed by willingness to pay. Given the debate over the potential for ANP to reduce the harm from smoking, these results are important in understanding the impact of free trial offers on adoption of ST product as a strategy to reduce harm from tobacco use.

Introduction: Health warning labels (HWLs) on tobacco packaging can be used to provide smoking cessation information, but the impact of this information is not well understood., Methods: Online consumer panels of adult smokers from Canada, Australia and Mexico were surveyed in September 2012, January 2013 and May 2013; replenishment was used to maintain sample sizes of 1000 participants in each country at each wave. Country-stratified logistic Generalised Estimating Equation (GEE) models were estimated to assess correlates of citing HWLs as a source of information on quitlines and cessation websites. GEE models also regressed having called the quitline, and having visited a cessation website, on awareness of these resources because of HWLs., Results: At baseline, citing HWLs as a source of information about quitlines was highest in Canada, followed by Australia and Mexico (33%, 19% and 16%, respectively). Significant increases over time were only evident in Australia and Mexico. In all countries, citing HWLs as a source of quitline information was significantly associated with self-report of having called a quitline. At baseline, citing HWLs as a source of information about cessation websites was higher in Canada than in Australia (14% and 6%, respectively; Mexico was excluded because HWLs do not include website information), but no significant changes over time were found for either country. Citing HWLs as a source of information about cessation websites was significantly associated with having visited a website in both Canada and Australia., Conclusions: HWLs are an important source of cessation information., (Published by the BMJ Publishing Group Limited.

This study examines the effects of different cigarette package warnings in Australia, Canada and the United Kingdom up to 5 years post-implementation. The data came from the International Tobacco Control Surveys. Measures included salience of warnings, cognitive responses, forgoing cigarettes and avoiding warnings. Although salience of the UK warnings was higher than the Australian and Canadian pictorial warnings, this did not lead to greater levels of cognitive reactions, forgoing or avoiding. There was no difference in ratings between the Australian and UK warnings for cognitive responses and forgoing, but the Canadian warnings were responded to more strongly. Avoidance of the Australian warnings was greater than to UK ones, but less than to the Canadian warnings. The impact of warnings declined over time in all three countries. Declines were comparable between Australia and the United Kingdom on all measures except avoiding, where Australia had a greater rate of decline; and for salience where the decline was slower in Canada. Having two rotating sets of warnings does not appear to reduce wear-out over a single set of warnings. Warning size may be more important than warning type in preventing wear-out, although both probably contribute interactively., (© The Author 2014. Published by Oxford University Press.

Introduction: The purpose of this study was to evaluate the prevalence and correlates of use of nicotine-containing tobacco products such as cigars, pipe tobacco, and cigarettes that promise less exposure to toxins; e-cigarettes; and smokeless tobacco products among a cohort of conventional cigarette smokers followed over the past decade. We also evaluated associations between use of such products and cigarette quitting., Methods: Participants were 6,110 adult smokers in the United States, who were interviewed as part of the International Tobacco Control Four Country Survey between 2002 and 2011. Respondents reported their concurrent use of other smoked tobacco products (including cigars, pipe tobacco, and cigarillos), smokeless tobacco products (including chewing tobacco, snus, and snuff), unconventional cigarettes (including Omni, Accord, and Eclipse), and electronic cigarettes. Prevalence and correlates of use and associations between use and cigarette quitting were assessed using regression analyses via generalized estimating equations., Results: Most cigarette smokers did not use unconventional tobacco products, although use of any of these products started to rise at the end of the study period (2011). For each type of tobacco product evaluated, use was most prevalent among those aged 18-24 years. Smokers who did use unconventional tobacco products did not experience a clear cessation advantage., Conclusions: During the past decade, relatively few cigarette smokers reported also using other tobacco products. Those that did use such products were no more likely to stop using conventional cigarettes compared with those who did not use such products.

Aim: To evaluate the population effectiveness of stop-smoking medications while accounting for potential recall bias by controlling for quit attempt recency., Design: Prospective cohort survey., Setting: United Kingdom, Canada, Australia and the United States., Participants: A total of 7436 adult smokers (18+ years) selected via random digit dialling and interviewed as part of the International Tobacco Control Four Country Survey (ITC-4) between 2002 and 2009. Primary analyses utilized the subset of respondents who participated in 2006 or later (n = 2550)., Measurements: Continuous abstinence from smoking for 1 month/6 months., Findings: Among participants who recalled making a quit attempt within 1 month of interview, those who reported using varenicline, bupropion or nicotine patch were more likely to maintain 6-month continuous abstinence from smoking compared to those who attempted to quit without medication [adjusted odds ratio (OR) 5.84, 95% confidence interval (CI) (2.12-16.12), 3.94 (0.87-17.80), 4.09 (1.72-9.74), respectively]; there were no clear effects for oral NRT use. Those who did not use any medication when attempting to quit tended to be younger, to be racial/ethnic minorities, to have lower incomes and to believe that medications do not make quitting easier., Conclusions: Consistent with evidence from randomized controlled trials, smokers in the United Kingdom, Canada, Australia and the United States are more likely to succeed in quit attempts if they use varenicline, bupropion or nicotine patch. Previous population studies that failed to find an effect failed to control adequately for important sources of bias., (Published 2012.

Awareness of the health risks of smoking is an important factor in predicting smoking-related behaviour; however, little is known about the knowledge of health risks in low-income countries such as India. The present study examined beliefs about the harms of smoking and the impact of health knowledge on intentions to quit among a sample of 249 current smokers in both urban and rural areas in two states (Maharashtra and Bihar) from the 2006 TCP India Pilot Survey, conducted by the ITC Project. The overall awareness among smokers in India of the specific health risks of smoking was very low compared to other ITC countries, and only 10% of respondents reported that they had plans to quit in the next six months. In addition, smokers with higher knowledge were significantly more likely to have plans to quit smoking. For example, 26.2% of respondents who believed that smoking cause CHD and only 5.5% who did not believe that smoking causes CHD had intentions to quit (χ² = 16.348, p < 0.001). Important differences were also found according to socioeconomic factors and state: higher levels of knowledge were found in Maharashtra than in Bihar, in urban compared to rural areas, among males, and among smokers with higher education. These findings highlight the need to increase awareness about the health risks of smoking in India, particularly in rural areas, where levels of education and health knowledge are lower.

Objectives: To examine the relationship between a belief about Food and Drug Administration (FDA) safety evaluation of cigarettes and smoking risk perceptions., Methods: A nationally representative, random-digit-dialed telephone survey of 1046 adult current cigarette smokers., Results: Smokers reporting that the FDA does not evaluate cigarettes for safety (46.1%), exhibited greater comprehension of the health risks of smoking and were more likely (48.5%) than other participants (33.6%) to report quit intentions. Risk perceptions partially mediated the relationship between FDA evaluation belief and quit intentions., Conclusions: These findings highlight the need for proactive, effective communication to the public about the aims of new tobacco product regulations.

Background: Since 2006, banning smoking in cars with children has become a rapidly growing tobacco control policy. However, to date, there have been few studies examining support and correlates of support for car smoking bans, and none of the existing studies have been international in nature. We conducted such a study among smokers in four countries., Methods: 6716 adult current smokers from the 2007 Wave of the International Tobacco Control Four Country Survey, a nationally representative, longitudinal cohort telephone survey of smokers in the USA, Canada, UK and Australia. Controlling for demographics, heaviness of smoking, smoking health knowledge/beliefs and quit intentions, we compared support and correlates of support for banning smoking in cars with children across the four countries., Results: The majority of smokers supported banning smoking in cars with children. Support was highest in Australia (83%), followed by the UK (75%) and Canada (74%); support was lower-but still high-in the USA (60%). Support was highest among smokers who: had stronger quit intentions, were lighter smokers, had lower education, had no children in the home, believed that cigarette smoke is dangerous to non-smokers and could cause asthma in children, and were concerned about modelling smoking to children., Conclusions: These findings indicate that a majority of smokers in the four countries support banning smoking in cars with children, and lend support to banning smoking in cars with children. Additionally, they suggest that support may be increased by educating smokers about the dangers of cigarette smoke exposure.

Introduction: Limited longitudinal studies on smoking cessation have been reported in Asia, and it remains unclear whether determinants of quitting are similar to those found in Western countries. This study examined prospective predictors of smoking cessation among adult smokers in Thailand and Malaysia., Methods: Four thousand and four smokers were surveyed in Malaysia and Thailand in 2005. Of these, 2,426 smokers were followed up in 2006 (61% retention). Baseline measures of sociodemographics, dependence, and interest in quitting were used to predict both making quit attempts and point prevalence maintenance of cessation., Results: More Thai than Malaysian smokers reported having made quit attempts between waves, but among those who tried, the rates of staying quit were not considerably different between Malaysians and Thais. Multivariate analyses showed that smoking fewer cigarettes per day, higher levels of self-efficacy, and more immediate quitting intentions were predictive of both making a quit attempt and staying quit in both countries. Previous shorter quit attempts and higher health concerns about smoking were only predictive of making an attempt, whereas prior abstinence for 6 months or more and older age were associated with maintenance., Discussion: In Malaysia and Thailand, predictors of quitting activity appear to be similar. However, as in the West, predictors of making quit attempts are not all the same as those who predict maintenance. The actual predictors differ in potentially important ways from those found in the West. We need to determine the relative contributions of cultural factors and the shorter history of efforts to encourage quitting in Asia.

Introduction: The present study reports on the prevalence of smoke-free homes, the characteristics of participants who adopted a smoke-free home policy, and the association between smoke-free homes and subsequent predictors of smoking cessation., Methods: Data are reported on 4,963 individuals who originally participated in the Community Intervention Trial for Smoking Cessation between 1988 and 1993 and completed follow-up surveys in 2001 and 2005. The relationship between home smoking policy and smoking behavior was examined with a multivariate regression model., Results: Among those who were smokers at the 2001 follow-up, the percentage reporting that no smoking was allowed in their home increased from 29% in 2001 to 38% in 2005. Smokers most likely to adopt smoke-free home policies between 2001 and 2005 were males, former smokers, and those who had lower levels of daily cigarette consumption (among those who continued to smoke), those with higher annual household incomes, and those with no other smokers in the household. Some 28% of smokers with smoke-free homes in 2001 reported that they had quit smoking by 2005 compared with 16% of those who allowed smoking in their homes (odds ratio [OR] = 1.7, 95% CI = 1.4-2.2), and baseline quitters with smoke-free homes also were less likely to relapse (OR = 0.6, 95% CI = 0.4-0.8)., Discussion: Smoke-free homes are becoming more prevalent, and they are a powerful tool not only to help smokers stop smoking but also to help keep those who quit from relapsing back to smoking.

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<0.001), and leveling off to 45.0% in 2020 (2018 vs 2020, p=0.91). Support was highest among former smokers and lowest among daily smokers in all three survey years. Support for PHWs at all survey years was significantly higher among those who formerly smoked, were younger (aged 18-39 vs ≥40 years), those who identified as Black (vs White), and planned to quit smoking (vs not planning to quit). There were no differences by income level, education level, or sex. CONCLUSIONS Nearly half of US adults who smoke cigarettes or quit smoking supported PHWs in 2020, with support being higher among younger adults, ethnic minorities, and those who formerly smoked. Support increased between 2016 and 2018, but not between 2018 and 2020. Similar to other studies, fewer current and former smokers supported PHWs compared to the US adult general population.

In May 2020, New York State restricted the sale of flavored e-liquids, excluding tobacco flavor. We conducted a Web-based survey to assess support and changes in use behavior between July and October 2020 (n = 946), with a follow-up between April and June 2021 (n = 542). Most electronic nicotine delivery system (ENDS) users (n = 82/55) continued to use, with 39%/33% reporting continuing to purchase flavored e-liquids, 20%/32% reporting using tobacco flavor, 5%/6% reporting quitting ENDS and smoking cigarettes, and 8%/3% reporting quitting ENDS and not smoking cigarettes. In 2020, 65% of non-users, 53% of cigarette users, 34% of cigarette/ENDS users, and 18% of ENDS users supported this policy restriction on e-liquids. Similar results were observed in 2021. Many ENDS users continued purchasing flavored e-liquids, suggesting that compliance with the policy can be improved. Cigarette smoking did not appear to increase. Continued evaluation of how restrictions on sales of products influence use is critical to understanding the long-term impact on behavior. [ABSTRACT FROM AUTHOR]

Background and Aims: The prevalence of hookah smoking has increased in the United States since at least 2010, especially among youth and young adults. This study assessed self‐reported reasons for hookah smoking cessation and transition to or maintenance of high‐frequency hookah smoking among current hookah smokers. Design Separately analyzed data from the Population Assessment of Tobacco and Health (PATH) study, a longitudinal cohort study. Frequency of and reasons for hookah smoking were ascertained at wave 1 (2013–14); frequency of hookah smoking and past‐year cessation were ascertained at wave 2 (2014–15). Weighted multivariable logistic and ordinal logistic regression models were fitted to predict hookah smoking cessation and frequency of hookah smoking at wave 2, respectively, accounting for demographic and behavioral risk factors, reasons for hookah smoking and frequency of hookah smoking at wave 1. Setting: United States. Participants: A total of 693 youth and 4400 adult past‐year hookah smokers. Measurements Self‐reported tobacco‐use patterns and associated health behaviors were measured via audio computer‐assisted self‐interviews (ACASI). Findings At wave 1, 5.9% of youth and 7.5% of adults were past‐year hookah smokers. Among all age groups, the leading reasons for hookah smoking were enjoyment of socializing while smoking, the availability of appealing flavors and believing that it was less harmful than cigarette smoking. The odds of cessation were lower for adults who liked hookah flavors [adjusted odds ratio (aOR) = 0.40; 95% confidence interval (CI) = 0.26–0.62] compared with adults who did not like hookah flavors. The odds of transitioning to, or maintaining, monthly or more frequent hookah smoking at wave 2, compared with cessation or less than monthly smoking, were higher for adults who liked hookah flavors [adjusted proportional odds ratio (aPOR) = 2.10; 95% CI = 1.48–2.99 and enjoyed socializing while smoking hookah (aPOR = 1.82; 95% CI =1.13–2.94) compared with adults who did not like hookah flavors or socializing. Conclusion: The availability of appealing flavors, affordability and socialization while smoking hookah in the United States are associated with reduced likelihood of cessation and increased likelihood of high‐frequency hookah smoking.

Introduction: We characterised tobacco use, cessation patterns, and patient satisfaction with a cessation support program at an NCI Designated Comprehensive Cancer Center following a mandatory tobacco assessment and automatic referral. Methods: A 3-month follow-up survey (via web, paper, or telephone) was administered between March 2013 and November 2013 for all patients referred to and contacted by a cessation support service, and who consented to participation three months prior to administration. Patients were asked about their perceived importance and self-efficacy to quit smoking, quit attempts, and satisfaction with the cessation service. Results: Fifty-two percent (257/499) of patients who participated in the cessation support service, and consented to be contacted again, completed a follow-up survey. Of those who participated, 9.7% were referred to the service as having recently quit tobacco (in the past 30 days) and 23.6% reported having quit at the time of first contact. At the 3-month follow-up, 48.1% reported being smoke-free for the previous seven days. When patients were asked about their experience with the cessation service, 86.4% reported being very or mostly satisfied with the service, and 64.3% reported that their experience with the service increased their satisfaction with the care received at the cancer centre. Conclusions: Our findings suggest that recently diagnosed cancer patients are aware that quitting tobacco is important, are making attempts to quit, and are amenable to an opt-out automatic referral cessation support service as part of their cancer care.

Introduction: Waking at night to smoke can also serve as an indicator of dependence and treatment success.Aims: We sought to examine whether night smoking is associated with features of smoking behaviour in a non-treatment-seeking sample of adult smokers in the general population.Methods: Data for this study come from 1,062 current smokers obtained from an opt-in online panel in July 2010. Night smoking and night craving to smoke were assessed by questionnaire, and dependence was assessed by the Fagerstrom Test for Nicotine Dependence (FTND). Relationships were assessed using linear, logistic, and negative binomial regression.Findings: Overall, 20.6% reported that they woke at night to smoke. FTND scores were substantially higher in those reporting night smoking. Those who reported night cravings were more likely to report quit intentions. Night smokers made 3.6 actual quit attempts (95% CI: 2.8, 4.5) per year, adjusted for other model factors, compared to 2.7 (2.2, 3.2) attempts for night cravers and 2.2 (1.8, 2.7) attempts for smokers who reported neither.Conclusions: Overall, night smokers reported higher nicotine dependence than cravers and those who experienced neither. The current study adds to a growing literature pointing to the importance of overnight smoking as an indicator of nicotine dependence. [ABSTRACT FROM PUBLISHER]

Guided by the extended parallel process model (EPPM) and reactance theory, this study examined the relationship between efficacy beliefs, reactance, and adult smokers' responses to pictorial health warning labels (HWL) on cigarette packaging, including whether efficacy beliefs or reactance modify the relationship between HWL responses and subsequent smoking cessation behavior. Four waves of data were analyzed from prospective cohorts of smokers in Australia and Canada (n = 7,120 observations) over a period of time after implementation of more prominent, pictorial HWLs. Three types of HWL responses were studied: psychological threat responses (i.e., thinking about risks from smoking), forgoing cigarettes due to HWLs, and avoiding HWLs. The results from Generalized Estimating Equation models indicated that stronger efficacy beliefs and lower trait reactance were significantly associated with greater psychological threat responses to HWLs. Similar results were found for models predicting forgoing behavior, although response efficacy was inversely associated with it. Only response efficacy was significantly associated with avoiding HWLs, showing a positive relationship. Higher self-efficacy and stronger responses to HWLs, no matter the type, were associated with attempting to quit in the followup period; reactance was unassociated. No statistically significant interactions were found. These results suggest that stronger efficacy beliefs and lower trait reactance are associated with some stronger responses to fear-arousing HWL responses; however, these HWL responses appear no less likely to lead to cessation attempts among smokers with different levels of self-efficacy to quit, of response efficacy beliefs, or of trait reactance against attempts to control their behavior.

Introduction: In December 2008, the Federal Trade Commission (FTC) took action that prompted the removal of nicotine and tar listings from cigarette packs and ads. As of June 2010, the US Family Smoking Prevention and Tobacco Control Act prohibited the use of explicit or implicit descriptors on tobacco packaging or in advertising that convey messages of reduced risk or exposure, specifically including terms like "light," "mild," and "low" and similar descriptors. This study evaluates the effect of these two policy changes on smokers' beliefs, experiences and perceptions of different cigarettes.Methods: Using generalized estimating equations models, this study analyzed survey data collected between 2002 and 2013 by the International Tobacco Control Policy Evaluation Study regarding US smokers' beliefs, experiences, and perceptions of different cigarettes.Results: Between 2002 and 2013, smoker misperceptions about "light" cigarettes being less harmful did not change significantly and remained substantial, especially among those who reported using lower-strength cigarettes. After the two policy changes, reported reliance on pack colors, color terms, and other product descriptors like "smooth" to determine cigarette strength style trended upward.Conclusions: Policies implemented to reduce smoker misperceptions that some cigarettes are safer than others appear to have had little impact. Because of pack colors, color terms, descriptors such as "smooth," cigarette taste or feel, and possibly other characteristics, millions of smokers continue to believe, inaccurately, that they can reduce their harms and risks by smoking one cigarette brand or sub-brand instead of another, which may be delaying or reducing smoking cessation.Implications: What this study adds: This study confirms that US policies to reduce smoker misperceptions that some cigarettes are less harmful than others have not been successful. Following the removal of light/low descriptors and tar and nicotine numbers from cigarette packs and ads, pack colors, color words, other descriptors (eg, smooth), and sensory experiences of smoother or lighter taste have helped smokers to continue to identify their preferred cigarette brand styles and otherwise distinguish between which brands and styles they consider "lighter" or lower in tar and, mistakenly, less harmful than others. These findings provide additional evidence to support new enforcement or regulatory action to stop cigarettes and their packaging from misleading smokers about relative risk, which may be reducing or delaying quit attempts.

Introduction: Attempts to validate the Brief Wisconsin Inventory of Smoking Dependence Motives (WISDM) have produced mixed results. The objectives for the current research were to (1) evaluate the test-retest reliability, internal consistency, and concurrent validity for each of the motive scales (2) evaluate three models to determine fit based on previous research: (i) 11-factor model, (ii) 11-factor model with four error covariances specified by previous research, and (iii) 11-factor model with two higher order primary and secondary dependence motive factors, and (3) evaluate the discriminant and convergent validity of the Brief WISDM scales.Methods: Smoking adults aged 18-65 completed a survey about their smoking behaviors and nicotine dependence with a web-based instrument that was administered at a 3-month test-retest interval. Psychometric properties and test-retest reliability were evaluated for each instrument. The 11-factor Brief WISDM was evaluated with confirmatory factor analyses; the scales were evaluated for convergent and discriminant validity.Results: The Brief WISDM demonstrated good to excellent test-retest reliability. Confirmatory factor analysis showed the model with the second order primary and secondary dependence motive factors demonstrated the best fit for the data at both administrations. Discriminant validity issues were present for most of the primary dependence motive scales.Conclusions: To date, the theoretically derived smoking motives for the Brief WISDM have demonstrated mixed support when submitted to confirmatory factor analysis. While these scales tap critical motives of nicotine dependence, further refinement of primary dependence motives is necessary to ensure each latent variable assesses a unique construct.

Introduction Health warning labels (HWLs) on tobacco packaging can be used to provide smoking cessation information, but the impact of this information is not well understood. Methods Online consumer panels of adult smokers from Canada, Australia and Mexico were surveyed in September 2012, January 2013 and May 2013; replenishment was used to maintain sample sizes of 1000 participants in each country at each wave. Country-stratified logistic Generalised Estimating Equation (GEE) models were estimated to assess correlates of citing HWLs as a source of information on quitlines and cessation websites. GEE models also regressed having called the quitline, and having visited a cessation website, on awareness of these resources because of HWLs. Results At baseline, citing HWLs as a source of information about quitlines was highest in Canada, followed by Australia and Mexico (33%, 19% and 16%, respectively). Significant increases over time were only evident in Australia and Mexico. In all countries, citing HWLs as a source of quitline information was significantly associated with self-report of having called a quitline. At baseline, citing HWLs as a source of information about cessation websites was higher in Canada than in Australia (14% and 6%, respectively; Mexico was excluded because HWLs do not include website information), but no significant changes over time were found for either country. Citing HWLs as a source of information about cessation websites was significantly associated with having visited a website in both Canada and Australia. Conclusions HWLs are an important source of cessation information. [ABSTRACT FROM AUTHOR]

Background: In the U.S., limited evidence exists on the impact of colors and brand imagery used in cigarette pack design. Purpose: This study examined the impact of pack design, product descriptors, and health warnings on risk perception and brand appeal. Methods: A cross-sectional mall-intercept study was conducted with 197 adult smokers and 200 nonsmokers in Buffalo NY from June to July 2009 (data analysis from July 2009 to December 2010). Participants were shown 12 sets of packs randomly; each set varied by a particular design feature (color, descriptor) or warning label style (text versus graphic, size, attribution, message framing). Packs were rated on criteria including risk perceptions, quit motivation, and purchase interest. Results: Participants selected larger, pictorial, and loss-framed warning labels as more likely to attract attention, encourage thoughts about health risks, motivate quitting, and be most effective. Participants were more likely to select packs with lighter color shading and descriptors such as light, silver, and smooth as delivering less tar, smoother taste, and lower health risk, compared to darker-shaded or full-flavor packs. Additionally, participants were more likely to select the branded compared to plain white pack when asked which delivered the most tar, smoothest taste, was more attractive, appealed to youth aged <18 years, and contained cigarettes of better quality. Conclusions: The findings support larger, graphic health warnings that convey loss-framed messages as most effective in communicating health risks to U.S. adults. The results also indicate that color and product descriptors are associated with false beliefs about risks. Plain packaging may reduce many of the erroneous misperceptions of risk communicated through pack design features. [ABSTRACT FROM AUTHOR]

The objective of this study was to test the efficacy of specially designed educational materials to correct misperceptions held by smokers about nicotine, nicotine medications, low tar cigarettes, filters and product ingredients. To accomplish this, 682 New York State Smokers’ Quitline callers were randomized to one of two groups: control group received counseling, nicotine patches and quit smoking guide; and experimental group received counseling, nicotine patches, quit guide, plus information about cigarette characteristics mailed in a brand-tailored box. Participants were contacted 1 month later to assess knowledge about cigarettes and actions taken to alter smoking behavior. The results found that respondents in the experimental condition were more likely to report using and sharing the test materials with others compared with the control condition. Overall mean knowledge scores for the experimental group were slightly higher compared with those who received the standard materials. Knowledge of cigarette ingredients was not related to quit attempts or quitting smoking. This study found that the experimental materials were better recalled and contributed to higher levels of knowledge about specific cigarette design features; however, this did not translate into changes in smoking behavior.

Introduction: This article examines trends in switching between menthol and nonmenthol cigarettes, smoker characteristics associated with switching, and associations among switching, indicators of nicotine dependence, and quitting activity. Methods: Participants were 5,932 adult smokers in the United States interviewed annually as part of the International Tobacco Control Four Country Survey between 2002 and 2011. Generalized estimating equations (GEEs) were used to examine the prevalence of menthol cigarette use and switching between menthol and nonmenthol cigarettes (among 3,118 smokers who participated in at least 2 consecutive surveys). We also evaluated characteristics associated with menthol cigarette use and associations among switching, indicators of nicotine dependence, and quitting activity using GEEs. Results: Across the entire study period, 27% of smokers smoked menthol cigarettes; prevalence was highest among Blacks (79%), young adults (36%), and females (30%). Prevalence of switching between menthol and nonmenthol cigarettes was low (3% switched to menthol and 8% switched to nonmenthol), and switchers tended to revert back to their previous type. Switching types was not associated with indicators of nicotine dependence or quit attempts. However, those who switched cigarette brands within cigarette types were more likely to attempt to quit smoking. Conclusions: While overall switching rates were low, the percentage who switched from menthol to nonmenthol was significantly higher than the percentage who switched from nonmenthol to menthol. An asymmetry was seen in patterns of switching such that reverting back to menthol was more common than reverting back to nonmenthol, particularly among Black smokers. [ABSTRACT FROM PUBLISHER]

Introduction: Limited longitudinal studies on smoking cessation have been reported in Asia, and it remains unclear whether determinants of quitting are similar to those found in Western countries. This study examined prospective predictors of smoking cessation among adult smokers in Thailand and Malaysia. Methods: Four thousand and four smokers were surveyed in Malaysia and Thailand in 2005. Of these, 2,426 smokers were followed up in 2006 (61% retention). Baseline measures of sociodemographics, dependence, and interest in quitting were used to predict both making quit attempts and point prevalence maintenance of cessation. Results: More Thai than Malaysian smokers reported having made quit attempts between waves, but among those who tried, the rates of staying quit were not considerably different between Malaysians and Thais. Multivariate analyses showed that smoking fewer cigarettes per day, higher levels of self-efficacy, and more immediate quitting intentions were predictive of both making a quit attempt and staying quit in both countries. Previous shorter quit attempts and higher health concerns about smoking were only predictive of making an attempt, whereas prior abstinence for 6 months or more and older age were associated with maintenance. Discussion: In Malaysia and Thailand, predictors of quitting activity appear to be similar. However, as in the West, predictors of making quit attempts are not all the same as those who predict maintenance. The actual predictors differ in potentially important ways from those found in the West. We need to determine the relative contributions of cultural factors and the shorter history of efforts to encourage quitting in Asia. [ABSTRACT FROM PUBLISHER]

Introduction: Tobacco-free oral nicotine products are an emerging class of noncombustible nicotine products. Oral nicotine product sales have increased since 2016, although little research has investigated consumer awareness, use, or correlates of oral nicotine product use. The purpose of this analysis was to assess the prevalence and correlates of oral nicotine product awareness and use.Methods: This paper is a cross-sectional analysis of 2,507 U.S. participants from Wave 3 (February-June 2020) of the International Tobacco Control Four Country Smoking and Vaping Survey, a population-based survey of current and former cigarette smokers and nicotine vaping product users in the U.S. Oral nicotine product awareness and use prevalence were compared with those of heated tobacco products. Analyses conducted in late 2021 assessed the correlates of oral nicotine product awareness and use such as demographic characteristics, tobacco use (cigarettes, nicotine vaping products, smokeless tobacco), and tobacco quit attempts.Results: Almost 1 in 5 respondents claimed to have heard of oral nicotine products, 3.0% reported ever use, and 0.9% were current users, all of which were lower than for heated tobacco products. Ever use of oral nicotine products was more common among younger adults (e.g., aged 18-24 years), males, and current users of smokeless tobacco. Oral nicotine product prevalence was higher among those who reported having made attempts to stop smoking or vaping.Conclusions: Oral nicotine product use was low among current and former smokers and nicotine vaping product users. Oral nicotine product users were demographically similar to use among individuals who smoke/vape and also use smokeless tobacco. Future studies are needed to understand emerging oral nicotine products, particularly whether they are being used as product supplements (dual use), replacements (switching), or cessation aids (quitting).

Background: Electronic nicotine delivery systems (ENDS) initially emerged in 2003 and have since become widely available globally, particularly over the Internet. Purpose: Data on ENDS usage patterns are limited. The current paper examines patterns of ENDS awareness, use, and product-associated beliefs among current and former smokers in four countries. Methods: Data come from Wave 8 of the International Tobacco Control Four-Country Survey, collected July 2010 to June 2011 and analyzed through June 2012. Respondents included 5939 current and former smokers in Canada (n=1581); the U.S. (n=1520); the United Kingdom (UK; n=1325); and Australia (n=1513). Results: Overall, 46.6% were aware of ENDS (U.S.: 73%, UK: 54%, Canada: 40%, Australia: 20%); 7.6% had tried ENDS (16% of those aware of ENDS); and 2.9% were current users (39% of triers). Awareness of ENDS was higher among younger, non-minority smokers with higher incomes who were heavier smokers. Prevalence of trying ENDS was higher among younger, nondaily smokers with a high income and among those who perceived ENDS as less harmful than traditional cigarettes. Current use was higher among both nondaily and heavy (≥20 cigarettes per day) smokers. In all, 79.8% reported using ENDS because they were considered less harmful than traditional cigarettes; 75.4% stated that they used ENDS to help them reduce their smoking; and 85.1% reported using ENDS to help them quit smoking. Conclusions: Awareness of ENDS is high, especially in countries where they are legal (i.e., the U.S. and UK). Because trial was associated with nondaily smoking and a desire to quit smoking, ENDS may have the potential to serve as a cessation aid. [ABSTRACT FROM AUTHOR]
