Importance: Concerns have been raised about the abuse liability of modern e-cigarettes that use acidic additives to form nicotine salts, making the inhalation of nicotine smoother than freebase nicotine., Objective: To examine the effects of nicotine form and concentration and e-liquid flavor on subjective effects ratings, vaping behavior, and nicotine uptake among young adults who use e-cigarettes., Design, Setting, and Participants: In this single-blind, within-participant, crossover randomized clinical trial, a convenience sample of young adults aged 21 to 25 years who currently used e-cigarettes was recruited from December 2021 to August 2023, for in-person research laboratory visits in Columbus, Ohio., Interventions: Participants completed up to 9 vaping sessions, starting with their usual e-cigarette brand in the first session followed by 1 of 8 laboratory-prepared e-liquids in a randomly assigned order in each subsequent session. Prepared e-liquids varied by nicotine form (salt-based vs freebase), nicotine concentration (5% vs 1% weight per weight), and flavor (menthol vs tobacco). Each session included a 5-minute, 10-puff standardized vaping period followed by 30 minutes of ad libitum vaping., Main Outcomes and Measures: At 4 time points (0, 5, 10, and 35 minutes) during each vaping session, plasma samples were collected for assessing nicotine uptake, and self-reports of urges, craving, and withdrawal were collected via questionnaires. Positive subjective effects were self-reported after 35 minutes of vaping using a visual analog scale; urges and cravings were reported using the Questionnaire of Smoking Urges (QSU). Puff topography data were collected throughout each vaping session., Results: Seventy-two participants (mean [SD] age, 22.4 [1.4] years; 42 [58.3%] female) who sampled at least 1 laboratory-prepared e-liquid composed the analytic sample. Salt-based (vs freebase) nicotine e-liquids increased nicotine intake, with 5% salt-based e-liquids delivering the highest mean plasma levels of nicotine (11.2 ng/mL [95% CI, 9.3-13.2 ng/mL] at 5 minutes; 17.2 ng/mL [95% CI, 14.3-20.1 ng/mL] at 35 minutes) irrespective of flavors. Higher positive subjective effect ratings (eg, for liking) were received by salt-based (42.8; 95% CI, 39.4-46.1) vs freebase (32.0; 95% CI, 28.6-35.3) nicotine, 1% (43.4; 95% CI, 40.2-46.6) vs 5% (31.2; 95% CI, 27.7-34.6) nicotine, and menthol-flavored (43.2; 95% CI, 39.7-46.7) vs tobacco-flavored (31.5; 95% CI, 28.4-34.7) e-liquids. Salt-based and 1% but not menthol-flavored nicotine elicited more intense puffing (eg, 25% [95% CI, 12%-40%] more total puffs for nicotine salts vs freebase). All study e-liquids reduced urges and cravings, with 5% vs 1% nicotine being more effective (mean [SE] QSU-Desire score at 35 minutes, 15.4 [0.5] vs 16.7 [0.5])., Conclusions and Relevance: In this crossover randomized clinical trial among young adult e-cigarette users, salt-based (vs freebase) nicotine e-liquids increased nicotine intake and yielded more positive subjective effects ratings and intense puffing behaviors, suggesting higher abuse potential. Restricting the level of acidic additives and menthol flavoring may reduce the addictiveness of e-cigarettes., Trial Registration: ClinicalTrials.gov Identifier: NCT05458895.

Background: Emerging data indicate that many adolescents and young adults ("youth") engage in infrequent, or occasional, e-cigarette use. However, little is known about this population as they are often subsumed into the broader "any past-30-day use" category used to define youth "current use." This study aimed to focus on infrequent e-cigarette use by youth, examining its correlates and transitional outcomes., Methods: Participants were from a prospective cohort study of youth (aged 15-24 at baseline). Among youth who had used e-cigarettes, we classified "infrequent use" as using e-cigarettes ≤5 days in the last 30 days (n=273) and "frequent use" as using e-cigarettes ≥6 days in the last 30 days (n=278). Descriptive statistics, Markov modeling, and logistic regression were utilized., Results: By the 12-month follow-up, 76.8% of those using infrequently at baseline remained in the "infrequent use" category, 6.3% reported no recent use, and 16.8% had escalated to the "frequent use" category. Among the youth using infrequently at baseline, those who did (vs. did not) escalate to frequent use by follow-up had higher baseline nicotine dependence and were more likely to have family members who used tobacco., Conclusions: Infrequent e-cigarette use is extremely common, and often fairly stable, among young people. Prevention efforts must certainly attempt to reduce escalation and attend to both individual and interpersonal factors (e.g., nicotine dependence, family use). Yet prevention efforts must additionally attend to the case of continued infrequent use, given the high prevalence of people in this category and their regular exposure to e-cigarette harms., Competing Interests: Declaration of Competing Interest None, (Copyright © 2024.

Aims: To measure nicotine delivery, vaping topography and subjective effects of current generations of disposable, cartridge-based and other types of electronic cigarettes (e-cigarettes) among young adults., Design, Setting, Participants: Observational, human laboratory assessment of e-cigarette use in Columbus, Ohio, USA (July 2020 to June 2021). Participants (n = 96, 60.4% female, age mean = 21.7 [standard deviation = 1.7] years, 82.4% white race) were identified via their participation in a cohort study or other convenience sampling and were 18 to 25 years old, vaped ≥4 days/week for ≥4 weeks and used other tobacco products for ≤5 days of past 30 days. Participants completed a pre-vaping questionnaire, vaped their usual brand of e-cigarette ad libitum for 30 min and completed a post-vaping questionnaire., Measurements: Outcome variables included pre- and post-vaping measures of plasma nicotine (t = 0 and t = 30, respectively) and craving and withdrawal symptoms, as well as vaping topography (e.g. flow rate and inter-puff interval), pre-vaping expectancies and post-vaping product appeal. Variables used to characterize the sample included demographics, e-cigarette and other tobacco use history, e-cigarette dependence and e-cigarette device characteristics (e.g. device type, flavor and nicotine form)., Findings: Participants reported moderate nicotine dependence on average via the E-Cigarette Dependence Scale (mean = 6.9 [standard deviation = 4.0]). Following 30 min of ad libitum vaping, participants achieved substantial plasma nicotine boost (mean = 18.8 [standard deviation = 14.5] ng/mL), corresponding with statistically significant decreases in withdrawal symptoms measured via the Minnesota Nicotine Withdrawal Scale (pre-vaping mean = 9.0 [standard deviation = 5.1], post-vaping mean = 4.3 [standard deviation = 3.9]; P-value <0.0001). Pre-vaping, participants reported moderate vaping expectancies (e.g. mean = 2.5 [standard deviation = 1.0] on a scale from 0 to 4 for smell and taste expectancies); post-vaping, participants reported high satisfaction (mean = 4.6 [standard deviation = 1.2] on a scale from 1 to 7) and moderate reward (mean = 2.9 [standard deviation = 1.2]) and respiratory sensations (mean = 3.7 [standard deviation = 1.6]). Nearly half of participants (47.9%) used disposable e-cigarettes, and most used a mint/menthol or fruit flavored (99.0%) and nicotine salt (98.9%) e-liquid., Conclusions: Among young adults in the United States, the latest generations of e-cigarettes appear to deliver large quantities of nicotine (similar to cigarettes) and significantly relieve withdrawal symptoms, and they are appealing., (© 2024 The Author(s).

Introduction: E-cigarette use is most prevalent among adolescents and young adults - and there are often misperceptions about product risk. The purpose of this study was to determine what nicotine information is provided on e-cigarette brand websites., Methods: Based on national and local surveys, we identified 44 e-cigarette brands commonly used in the US by adolescents and young adults. For each of these brands, their associated websites were analyzed for disclosed nicotine information. Specifically, for each brand's website, we coded whether there was information on nicotine concentration (recorded if a numerical value was provided such as '5% nicotine'), nicotine form (free-base, nicotine salts, or not stated), and nicotine type (tobacco-derived, synthetically derived, or not stated). Coding allowed for both lay (e.g. 'nic salts') as well as scientific (e.g. 'isomers') terms., Results: Of the 44 brands examined, all provided basic information on nicotine concentration (e.g. '5% nicotine'). However, 23% of brands did not disclose information on nicotine form (i.e. nicotine salt vs free-base), and 66% of brands did not disclose information on nicotine type (i.e. synthetic vs tobacco-derived)., Conclusions: Overall, these results suggest that the e-cigarette industry is not fully informing its consumers about the nicotine in their products. Given that nicotine form and type have implications for e-cigarette addiction potential, these findings highlight a public health concern. There is a need for more comprehensive national regulations for mandating product constituents and emissions disclosures., Competing Interests: The authors have each completed and submitted an ICMJE form for Disclosure of Potential Conflicts of Interest and none was reported., (© 2024 Rykaczewski C. et al.)

Background: Among adolescents and young adults (AYAs), "current use" of electronic cigarettes (e-cigarettes) is commonly defined as any use in the past 30 days. However, few studies have examined differences among those within this broad category. This study examined characteristics of AYAs who used e-cigarettes at a low frequency (within the last 3 months but <6 days out of the past 30 days) and those who used e-cigarettes at a high frequency (6+ days out of the past 30 days)., Methods: We conducted cross-sectional analyses among 551 Ohio AYAs (15- to 24-year-olds) who reported using an e-cigarette to vape nicotine in the past 3 months. We used descriptive statistics and logistic regression to characterize those using e-cigarettes at a low frequency and a high frequency., Results: Among our sample of AYAs who reported past 3-month e-cigarette use, about half (50.8%) reported using an e-cigarette 6 or more days out of the past 30 days (ie, high frequency). In the multivariable analysis, reported nicotine dependence (Odds Ratio [OR]: 7.0, 95% CI: 4.8, 10.3) and current other tobacco product use (OR: 1.8, 95% CI: 1.1, 2.9) were associated with high-frequency e-cigarette use., Conclusion: Our results suggest that frequency of use is an important characteristic in understanding AYA e-cigarette use. Any use in the past 30 days may not be sensitive enough to understand dependence and tobacco-use behaviors. Further characterizing "current" e-cigarette use by frequency of use may provide meaningful information for public health professionals to better target intervention and cessation efforts to AYAs., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: This study examined the relationship between use patterns of a popular e-cigarette brand using nicotine salts, JUUL, and symptoms of nicotine dependence in a college cohort., Participants: Data for this study came from a prospective cohort of undergraduate students at a large Midwestern university from 2018 to 2019., Methods: Among participants who had ever tried a JUUL ( N  = 411), univariate and multivariable logistic regression were used to test the associations between use frequency (past 30-day use) and quantity (time to finish a pod) and nicotine dependence at follow up., Results: In the multivariable models, both frequency of use and quantity of use were associated with subsequent nicotine dependence, based on most indicators of dependence., Conclusions: As salt-based nicotine is now present in the most popular e-cigarette brands used by young people, such findings inform our contemporary understanding of e-cigarettes' addictive potential and can help inform campus-based interventions.

Introduction: In recent years, the nicotine in e-cigarettes has been available in either a 'free-base' (unprotonated) or 'nicotine salt' (protonated) form. Additionally, e-cigarette nicotine can be either 'synthetic' or 'tobacco-derived'. These dimensions of nicotine have implications for nicotine absorption, bioavailability and sensory experiences. However, it is unclear if the young people using e-cigarettes are aware of these nicotine dimensions., Methods: Data came from a cohort of Ohio youth (aged 15-24) who reported using an e-cigarette in the past 4 months (N=271). Participants were enrolled and provided background information in 2021; their 12-month follow-up survey asked about the presence, form and type of nicotine in their usual e-cigarette. Individuals who reported that they could distinguish between tobacco-derived and synthetic nicotine were additionally asked to describe the difference., Results: Of the 247 youth who reported that there was nicotine in their usual e-cigarette, 71.7% did not know whether it was free-base or nicotine salt and 75.7% did not know whether it was synthetic or tobacco-derived. Awareness was higher among youth who were using e-cigarettes at a greater frequency and quantity. The majority reported that they could not detect a difference between the experience of using synthetic vs tobacco-derived nicotine., Conclusions: These findings indicate the generally limited awareness about nicotine among youth who used e-cigarettes. Improvements in health communications and requirements for e-cigarette industry disclosures are necessary to ensure that consumers are better informed about the dimensions-and the risks-of the nicotine they are consuming., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: Oral nicotine pouches (ONPs) are novel products, gaining popularity and marketed as "tobacco-free" alternatives to cigarettes and smokeless tobacco (SLT), but their public health impact is unknown. This study qualitatively examined ONP appeal and perceptions among cigarette smokers and SLT users from Ohio Appalachia., Methods: In 2022, we conducted 10 virtual focus groups with smokers (n = 19) and smokeless tobacco users (n = 18) from Appalachia Ohio aged ≥21 to examine perceptions of risks and benefits, substitutability for cigarettes and SLT, and ONP marketing. We transcribed focus groups verbatim, thematically coded transcripts, and analyzed coded data for prominent themes., Results: Participants perceived ONPs to have similar or less risk than cigarettes/SLT but prominently discussed gastrointestinal and cardiovascular risks. Addiction risk was thought to be comparable to cigarettes/SLT, citing "nicotine is nicotine." Participants viewed ONPs to be situational rather than complete substitutes for cigarettes/SLT, viewing them as "cleaner," more socially acceptable, and discrete. Despite appealing features of ONP marketing, participants surmised ads would appeal to youth, new users, tobacco users seeking to cut down/quit, or to "high class," "white-collar" demographics., Conclusions: Participants' perceptions of ONPs and their marketing suggest ONPs are more likely to be used as situational versus complete substitutes for cigarettes and SLT. While situational substitution could exacerbate disparities in Appalachia by facilitating more frequent tobacco/nicotine use, complete substitution could reduce disparities. Research is needed to understand how perceptions, the appeal of ONP marketing, and novel product features translate to patterns of use to understand ONPs' potential impact., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Long et al.

Background: Adherence to COVID-19 protective measures is lowest for young people and males. The current study investigated characteristics associated with adherence to COVID-19 protective measures among male youth during the early months of the pandemic., Method: The study used data from a prospective cohort study among male youth with baseline assessment in 2015/2016 and follow-up measurements in 2019 and summer 2020. Attrition-weighted multivariable ordinal logistic and log-binomial regression models were used to assess factors associated with adherence to overall and specific adherence measures, respectively., Results: Among 571 male youth (mean age 18.5), overall adherence was higher for those who were older (OR: 1.15; 95% CI: 1.03-1.30), non-White (OR: 1.96; 95% CI: 1.20-3.32), and residing in an urban area (OR: 2.06; 95% CI: 1.46-3.01). Overall adherence was lower for those who had a history of being drunk (OR: 0.65; 95% CI: 0.42-0.99). For outdoor mask-wearing, adherence was higher for youth with attention-deficit disorder or attention-deficit/hyperactivity disorder (RR: 1.58; 95% CI: 1.16-1.97) and lower for youth who currently used tobacco products (RR: 0.42; 95% CI: 0.21-0.70). Before a statewide mask mandate was issued, non-White youth were more likely to report wearing masks in outdoor spaces than their non-Hispanic White peers (RR: 2.34; 95% CI: 1.75-3.23)., Conclusion: The study identified demographic, psychosocial, and behavioral factors associated with adherence to COVID-19 protective behaviors among male youth. The findings illustrate characteristics that could be leveraged for targeted preventive efforts during the ongoing pandemic and future outbreaks in a low-compliance group., (© 2022.

Background: Oral nicotine pouches (ONPs) are novel products that are marketed as "tobacco-free" alternatives to cigarettes and smokeless tobacco (ST). This study examined the effects of ONP packaging features on adult tobacco users' and non-users' product perceptions., Materials and Methods: Adult tobacco users (cigarettes, ST, and dual cigarette/ST) and non-users (total N = 301) viewed ONP pack images in a 4 × 3 × 2 between-subject experiment testing the effects of the displayed flavor (cool mint, coffee, dark frost, and smooth), nicotine concentration (none displayed on the package, 3 mg, and 6 mg), and addiction warning label (yes or no). The outcomes were perceived substitutability of ONPs for cigarettes and ST and perceived risks. We modeled the effects of tobacco user status and the experimental factors on these outcomes., Results: All tobacco user groups perceived ONPs to be significantly less harmful and less addictive than non-users. There were significant effects of nicotine concentration on perceived risks. Compared to packages that did not display nicotine concentration, packages displaying 6 mg nicotine concentration produced significantly lower perceived harm ( β = -0.23, 95% CI -0.44, -0.02), perceived addictiveness ( β = -0.28, 95% CI -0.51, -0.05), risk appraisals of harm ( β = -0.50, 95% CI -0.88, -0.12) and risk appraisals of addictiveness ( β = -0.53, 95% CI -0.95, -0.11)., Conclusions: The study findings demonstrate that the nicotine concentration displayed on ONP packaging can affect adults' perceptions of ONPs. Further research on the effects of ONP packaging features emphasizing nicotine (e.g., "tobacco free" nicotine claims) on tobacco users and non-users is needed to assess their potential public health impact.

Smokers are more likely to be low-income with limited access to health services. Although Medicaid expansion under the Patient Protection and Affordable Care Act improved access to care for low-income adults, long-term trends in health care access among low-income smokers remain uncharacterized. The study evaluated changes in five access measures among low-income nonelderly (19-64) adults (N = 28976) across smoking status using pooled data from a statewide survey in Ohio covering pre- (i.e., 2012) and post-Medicaid expansion periods (2015, 2017, and 2019) guided by a comprehensive framework of health care access. We found improvements in some, but not all, health care access measures among low-income smokers in the post-Medicaid-expansion period compared to the pre-expansion period. Compared to 2012, the odds for unmet dental care needs declined in 2015 (aOR = 0.67, 95 % CI = 0.45-1.01), 2017 (aOR = 0.53, 95 % CI = 0.35-0.81), and 2019 (aOR = 0.65, 95 % CI = 0.40-1.05) (p trend < 0.001). Similarly, the odds for unmet other health care needs (i.e., medical exams and supplies) were lower in 2015 (aOR = 0.64, 95 % CI = 0.39-1.06), 2017 (aOR = 0.56, 95 % CI = 0.34-0.93), and 2019 (aOR = 0.47, 95 % CI = 0.27-0.83) (p trend < 0.001). Difficulty paying medical bills was also significantly lower in 2015 (aOR = 0.62, 95 % CI = 0.43-0.89), 2017 (aOR = 0.57, 95 % CI = 0.39-0.83) and 2019 (aOR = 0.57, 95 % CI = 0.37-0.87) (p trend < 0.001). While there was notable progress in measures of affordability (i.e., paying medical bills) as well as care availability and accommodation (i.e., unmet needs), there were no meaningful changes in the approachability of care (i.e., having a usual source of care)., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)

Objectives: Nationwide implementation of Tobacco 21 (raising the legal sales age for all tobacco products to 21) is occurring against the backdrop of an electronic cigarette (e-cigarette) epidemic among young people, which makes Tobacco 21 evaluation difficult. To address this issue, we examined young adult use of e-cigarettes separately from use of other tobacco products. Our objective was to determine whether use changed after Tobacco 21 implementation and whether those changes differed by product., Methods: In Columbus, Ohio, which began enforcing Tobacco 21 in 2017, we surveyed incoming first-year undergraduates at a large, public university in 2016 (Cohort 1; n = 529) and re-contacted them in 2018. We surveyed a new sample of incoming first-year students in 2018 (Cohort 2; n = 611). Survey items assessed tobacco use, sources for obtaining tobacco, and attitudes surrounding Tobacco 21., Results: Both cross-sectional (Cohort 1 vs Cohort 2) and prospective (pre-post Tobacco 21 in Cohort 1) analyses indicated a slight decline in most tobacco use from 2016 to 2018, but e-cigarette use more than doubled during the same period. Students enrolled throughout the transition to Tobacco 21 (Cohort 1) perceived little effect of Tobacco 21 on peer use. The largest proportions (35.3%-43.5%) of combustible tobacco were obtained outside Columbus; 61.8% of e-cigarette users reported obtaining e-cigarettes through borrowing., Conclusions: Tobacco 21 was associated with reductions in combustible and smokeless tobacco use, but its impact was not sufficient to curb the surge in e-cigarette use. Tobacco 21 should be contextualized as part of a broader network of tobacco control efforts, including additional youth-access regulations, that may be needed to address e-cigarette use among young people.

Introduction: A growing body of evidence indicates that exposure to tobacco advertising among adolescents increases the likelihood of subsequent tobacco use. It is important to understand the process by which this occurs, in order to appropriately target factors for intervention. The objective of this study was to test whether attitudes towards tobacco advertising mediates the impact of advertising exposure on tobacco use., Methods: From an ongoing prospective cohort study of male adolescents (aged 11-16 at baseline), we recruited a subset of tobacco users and non-users to participate in an additional ecological momentary assessment (EMA) project (N = 164). Adolescents completed smartphone-based surveys 2-3 times/day over a 10-day period with items assessing their exposures and attitudes towards tobacco-related advertising. If participants reported exposure to tobacco advertising, they were asked about their attitudes toward it (how much they enjoyed it, liked it, and found it appealing)., Results: Adolescents who reported a greater amount of advertising exposure during the EMA period were more likely to report past-30-day tobacco use at their next cohort follow-up (6-12 months later). Moreover, the impact of advertising exposure on subsequent use was mediated by attitudes toward the tobacco advertisements, as reported during the EMA. This effect remained after controlling for baseline tobacco use., Conclusions: By pairing EMA with long-term follow-up, we identified attitudes as a mediator between adolescent advertising exposure and subsequent tobacco use. Interventions to lessen adolescents' positive attitudes toward tobacco advertisements may help disrupt this impact., (Copyright © 2022 Elsevier Ltd. All rights reserved.)

In this commentary, we discuss the concerning prevalence of cannabis use among young people who use e-cigarettes. National data in the U.S., as well as our own local data, indicate that dual use (i.e., nicotine e-cigarette use and cannabis use) is more common than e-cigarette use alone. Our commentary discusses why this dual use is a major concern for public health. We argue that continuing to examine e-cigarettes in isolation is not only impractical but also problematic, as it misses out on opportunities to understand additive and multiplicative health impacts, to share cross-knowledge, and to inform prevention and treatment. This commentary calls for more attention to dual use and concerted, equity-enhancing efforts from funders and researchers., (Copyright © 2022 by Alcohol Research Documentation, Inc.)

Introduction: The density of tobacco retailers varies by community characteristics such as poverty levels or racial and ethnic composition. However, few studies have investigated how specific types of tobacco retailers vary by community characteristics. Our objective was to assess how the types of tobacco retailers in Ohio varied by the characteristics of the communities in which they were located., Results: For all US Census tracts, convenience stores were the most common type of retailer selling tobacco. Yet, the prevalence of convenience stores was higher in high-poverty urban tracts than in low-poverty urban tracts. Discount stores were the second-most common type of tobacco retailer and were most prevalent in rural tracts and high-racial and ethnic minority urban tracts. Grocery stores, pharmacies, and vape or hookah shops typically had the highest prevalence in more advantaged tracts., Conclusion: Our findings demonstrate that the distribution of specific retailer types varies by community characteristics. The distribution of these retailer types has implications for product availability and price, which may subsequently affect tobacco use and cessation. To create equitable outcomes, policies should focus on retailers such as convenience and discount stores, which are heavily located in communities experiencing tobacco-related health disparities.

Despite reports suggesting young people are interested in quitting e-cigarettes, little work has examined predictors of quit outcomes. This study aimed to identify factors associated with quit outcomes among JUUL e-cigarette users in a longitudinal sample of young adults. We assessed undergraduate past-30-day JUUL users during autumn 2018 ( N = 225); Our outcomes included short-term quit attempts and interest (spring 2019), and long-term quit attempts (spring 2020). We used logistic regression to examine the associations between our outcomes and JUUL use characteristics, other tobacco use, and sociodemographic factors. Findings indicated 76% of users were interested in quitting JUUL, and more than 40% reported a quit attempt. Quit outcomes were not related to sociodemographics. Short-term quit outcomes were more likely among freshmen and less likely among recent cigarillo users. Heavy JUUL users were more likely to report short- and long-term quit attempts, but JUUL device owners were less likely to report short- and long-term quit attempts. Higher nicotine dependence reduced the likelihood of a long-term quit attempt. There is a need for policy level actions that address tobacco control among this population. Findings suggest a range of unique factors that can inform such policies and programs to curb young adult e-cigarette use.

Research has separately established that there are disparities in tobacco use, that greater tobacco retailer density (TRD) is positively associated with tobacco use, and that TRD is greater in high poverty and high racial/ethnic minority neighborhoods. Connecting these topics, this study examined the association between disparities in TRD and disparities in the prevalence of tobacco use among adults and youth. We obtained Ohio data on tobacco use from two statewide adult surveys and two sub-state regional youth surveys (2017-2019). Licensed tobacco retailers in Ohio were geocoded within census tracts. Disparity in TRD within regions across the state was defined as the ratio of TRD in high vs. low poverty (and in high vs. low racial/ethnic minority) census tracts per region. Disparity in cigarette smoking (adults) and any tobacco use (youth) was defined as the ratio of use prevalence among socioeconomically disadvantaged vs. non-disadvantaged (and racial/ethnic minority vs. non-minority) individuals. We estimated Pearson correlation coefficients to assess the linear relationship between the TRD disparity ratios and tobacco use disparity ratios. Poverty-based and race/ethnicity-based TRD disparities were positively associated with smoking disparities among adults. Negative associations between TRD disparities and tobacco use disparities were found among youth. To our knowledge, this is the first analysis directly linking TRD disparities and tobacco use disparities. Different adult and youth findings may be due to trends by age and product preferences. For adults in particular, this analysis suggests a detrimental effect of the tobacco retail environment on disadvantaged populations., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Objective: Examine trends in e-cigarette use, and Juul use specifically, among U.S. college students., Participants: In 2016, we established a cohort of 529 incoming first-year students to a large Midwestern University. In 2018, these students (now third-years) were re-contacted, and a new sample of 611 incoming first-year students was enrolled., Methods: First-year students in 2016 completed a survey assessing their e-cigarette use; in 2018, first- and second-year students reported on e-cigarette use, and use of Juul specifically., Results: From 2016 to 2018, past 30-day e-cigarette use rose from 5.9% to 27.7%. In 2018, for Juul alone, ever use was above 35% and past 30-day use was above 20% for both cohorts. Juul use did not differ by gender, but was associated with higher socioeconomic status (SES) and being White., Conclusions: Findings present disturbing possibilities for long-term nicotine addiction among the next generation, and underscore the need for a rapid public health response.

Purpose: The aim of this study was to compare prevalence of JUUL use and JUUL risk perceptions between adolescents living in an urban area versus Appalachian areas of the U.S., Methods: Data were drawn from a prospective cohort study of adolescent males (the Buckeye Teen Health Study, or BTHS); our cross-sectional analysis used data from one timepoint, collected between January and December 2019 (N = 873). Chi-square tests and multivariable logistic regression compared JUUL use prevalence and risk perceptions between participants in an urban Ohio county and nine predominantly rural Appalachian Ohio counties., Results: Over a quarter of the sample (29.2%) had ever used JUUL. In the unadjusted model, prevalence of JUUL use was similar between regions but Appalachian participants perceived JUUL as more harmful (p &lt; .001) and more addictive (p = .04) than urban participants. In the adjusted model, region was not significantly related to current JUUL use (OR: 1.20, 95% CI: 0.77, 1.87) or ever JUUL use (OR: 1.15, 95% CI: 0.83, 1.60)., Conclusions: JUUL use was similar between urban and Appalachian participants despite regional differences in risk perceptions. Interventions that only target risk perceptions may not be sufficient to prevent adolescent e-cigarette use, particularly in rural communities.

Objectives: To assess tobacco licensing-law strategies (eg, restricting the sale of tobacco near schools, banning the sale of tobacco in pharmacies) in terms of the equity of their impact and ability to correct existing disparities in tobacco retailer density., Methods: We geocoded all 11 392 tobacco retailers in Ohio, categorised neighbourhoods based on their demographic characteristics and calculated current disparities in tobacco retailer density. We next simulated the four main types of licensing-law strategies (capping-based, declustering-based, school-based and pharmacy-based), as well as strategy combinations. Finally, using statistical methods that account for residual spatial dependence, we evaluated how each strategy would impact density disparities., Findings: The most impactful licensing-law strategy depended on the type of community. School-based reductions were equitable for low-income, African-American and urban neighbourhoods (eg, eliminating retailers from 1000 feet of all schools produced a 9.2% reduction in the log retailer rate for neighbourhoods with a low prevalence of African-Americans and a 17.7% reduction for neighbourhoods with a high prevalence of African-Americans). Conversely, capping-based reductions were equitable for rural neighbourhoods. Pharmacy-based reductions demonstrated inequitable impacts., Conclusion: Licensing-law strategies could be a central tobacco control effort that benefits both the overall population and vulnerable communities. Policymakers will need to consider their community's characteristics when selecting licensing-law strategies to correct (rather than inadvertently widen) density disparities. But when matched with the appropriate strategy, high-risk communities could remove over 20% of their tobacco retailers., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Exposure to tobacco advertisements is associated with initiation of tobacco use among youth. The mechanisms underlying this association are less clear. We estimated longitudinal associations between youths' cognitive and affective responses to advertisements for cigarettes, e-cigarettes, and smokeless tobacco (SLT) and initiation of these products. N = 1220 Ohio-residing boys of ages 11-16 were recruited into a cohort in 2015 and 2016. Participants completed surveys every six months for four years. Surveys assessed cognitive and affective responses to tobacco advertisements (which included health warnings) and tobacco use after an advertisement viewing activity. We used mixed-effects Poisson regression models with robust standard errors to estimate risk of initiating use of each tobacco product according to participants' cognitive (i.e., memorability of health risks) and affective (i.e., likability of advertisement) responses to advertisements for that product. No associations between affective responses to advertisements and tobacco use outcomes were detected in adjusted models. However, finding health risks memorable was associated with reduced risk of ever smoking initiation (aRR = 0.57; 95% CI: 0.34, 0.95) and a reduced risk of ever SLT initiation that approached statistical significance (aRR = 0.61; 95% CI: 0.36, 1.05). Measures to increase saliency of health risks on cigarette and SLT advertisements might reduce use among youth.

Introduction: Tobacco 21 (T21), which sets the minimum legal sales age for tobacco to age 21, is now a national law in the United States. Although T21 is expected to help curb youth tobacco use, its impact may be dampened due to poor retailer compliance. Even within environments where enforcement is strong (ie, compliance checks are conducted with tough sanctions for violations), compliance might vary due to other factors., Aims and Methods: Three studies were conducted in Columbus, OH, where T21 became strongly enforced in 2018. These studies examined how retailer compliance related to features of the neighborhood in which a retailer was located (Study 1), features of the retailer (Study 2), and features of the retail cashier (Study 3)., Results: Study 1 found that, after controlling for race- and age-based factors, retailers located in high (vs. low)-poverty neighborhoods had a lower likelihood of conducting identification (ID) checks. Study 2 found that ID checks were related to whether retailers displayed signage about T21, as required by the city law. Study 3 found that, among cashiers, T21 awareness (which was high) and perceptions about T21 (which were moderate) were not generally related to their retailer's compliance; having (vs. not having) scanners for ID checks was related to a higher likelihood of compliance., Conclusions: These studies emphasize the many, multilevel factors influencing T21 outcomes. Findings also indicate the potential for T21 to widen disparities in tobacco use, indicating the need for strategies to equitably improve T21 compliance., Implications: T21, which sets the minimum legal sales age for all tobacco products to age 21, is now a national law in the United States. Despite optimistic projections about what T21 could achieve, the ultimate impact may be dampened when it is applied in real-world settings. Our project revealed the many, multilevel factors influencing T21 compliance. Findings also indicate the potential for T21 to widen disparities in tobacco use if gaps in compliance persist. Strategies for equitably improving T21 compliance are discussed. This article is of relevance to areas interested in implementing or improving their local T21 enforcement., (© The Author(s) 2021.

Background: In January 2019, electronic nicotine delivery systems (ENDS) market leader Juul Labs (JUUL) launched an advertising campaign encouraging adult smokers to 'make the switch' from combustible cigarettes to JUUL. Our primary aim was to describe consumer perceptions of JUUL as communicated by members of JUUL's online social community via testimonials promoted on JUUL's website., Methods: User testimonials that were displayed on the JUUL website in December 2019 and January 2020 were collected and coded by three reviewers. A total of 220 testimonials were coded for primary and secondary themes (eight codes within four broader themes)., Results: Testimonial writers were, on average, 43.0 years old (range 28 to 74) and reported using JUUL for an average of 21.8 months (range 9 to 59 months). The most prominent theme, present in nearly half of the testimonials, was a description of how to use JUUL, with a mention of JUUL's benefits and tips on how to use the product. Nearly four in 10 statements encouraged smokers to give JUUL a try or noted that JUUL is a better product compared with cigarettes. About one in 10 statements focused on switching from smoking cigarettes to using JUUL., Conclusion: This study presents a foundation for understanding how adult users describe JUUL, including their experiences using JUUL to 'switch' or stop smoking. Currently, the effectiveness of ENDS for smoking cessation is not supported by substantial evidence; however, if cessation is defined as 'quitting combustible tobacco products', then regulators should be aware that switch and cessation messages may not be distinct., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Introduction: Electronic cigarette (e-cigarette) use among adolescents is associated with increased risk of subsequent cigarette smoking initiation in observational research. However, the existing research was not designed to answer causal questions about whether adolescent e-cigarette users would have initiated cigarette smoking if they had never used e-cigarettes. The current study used a causal inference framework to identify whether male adolescent e-cigarette users were at increased risk of initiating cigarette smoking and smokeless tobacco (SLT) use, compared to similar boys who had never used e-cigarettes., Methods: Boys from urban and Appalachian Ohio (N = 1220; ages 11-16 years at enrollment) reported use of e-cigarettes, cigarettes, and SLT at baseline and every six months for two years. A propensity score matching design was implemented, matching one e-cigarette user to two similar e-cigarette non-users. This analysis was completed in 25 multiple imputed datasets to account for missing data. Risk ratios (RRs) comparing risk of initiating cigarettes and SLT for e-cigarette users and nonusers were estimated., Results: Compared to non-users, e-cigarette users were more than twice as likely to later initiate both cigarette smoking (RR = 2.71; 95% CI: 1.89, 3.87) and SLT (RR = 2.42; 95% CI: 1.73, 3.38). They were also more likely to become current (i.e., past 30-day) cigarette smokers (RR = 2.20; 95% CI: 1.33, 3.64) and SLT users (RR = 1.64; 95% CI: 1.01, 2.64)., Conclusions: Adolescent boys who used e-cigarettes had increased risk of later initiating traditional tobacco products when compared to similar boys who had never used e-cigarettes., (Copyright © 2020 Elsevier Ltd.

In the 1930s United States, urban neighborhoods were graded on their desirability for investment (often based on race), a process known as "redlining." This study examined how historical redlining relates to current disparities in an important health determinant: tobacco retailer density. Analyses were conducted for thirteen Ohio cities using negative binomial models that accounted for retailer spatial dependence and controlled for present-day sociodemographic characteristics. Findings indicated that as grades increased from "Best" to "Still Desirable" to "Definitely Declining" and "Hazardous," retailer density increased monotonically. These results highlight the persisting impacts of redlining and how disparities, once intentionally created, can be perpetuated over time., (Copyright © 2021 Elsevier Ltd. All rights reserved.)

Tobacco retailer density is consistently associated with poor tobacco-use outcomes. The aim of this review was to synthesize the international evidence on density reduction policies. Searches in multiple databases resulted in 31 studies covering various policy approaches evaluated for their impact on retailer density. Findings indicate that bans on tobacco sales in pharmacies reduced retailer density, but perhaps not equitably. Prohibiting sale of tobacco near schools produced greater density reductions in higher-risk neighborhoods. Policies in combination were most effective. Future studies should measure the impact of these policies on tobacco use. Density-reduction policies offer a promising approach to tobacco control., (Copyright © 2020 Elsevier Ltd.

Objectives: The purpose of this study was to select a health warning message location on a waterpipe (WP) that both attracted visual attention and conveyed the risks associated with WP smoking. Methods: During June through November 2019, we conducted a within-subjects randomized experiment (N = 74) using eye tracking equipment to examine visual attention to 3 placements of a health warning on the WP (stem, water bowl, hose). We asked young adult ever WP users 3 questions about WP harm perceptions. We used generalized linear mixed models to examine the amount of fixation time spent on the placement locations; we used repeated measures ANOVA to model changes in harm perceptions. Results: There were statistically significant differences across all 3 placement locations; regardless of place, all HWLs attracted a comparable amount of visual attention. Absolute WP harm perceptions significantly increased following the experiment and remained significantly higher at the one-week follow-up, compared to baseline. Conclusions: Warnings on WPs attracted visual attention and increased harm perceptions, and those harm perceptions remained high one week after the experiment. Findings indicate the value of including a warning on the WP device, and underscore the necessity and effectiveness of those health warnings to combat WP harm misperceptions.

Purpose: Investigations into rural tobacco-related disparities in the U.S. are hampered by the lack of a standardized approach for identifying the rurality-and, consequently, the urbanicity-of an area. Therefore, the purpose of this study was to compare the most common urban/rural definitions (Census Bureau, OMB, RUCA, and Isolation) and determine which is preferable for explaining the geographic distribution of several tobacco-related outcomes (behavior, receiving a doctor's advice to quit, and support for secondhand smoke policies). Methods : Data came from The Current Population Survey Tobacco Use Supplement. For each tobacco-related outcome, one logistic regression was conducted for each urban/rural measure. Models were then ranked according to their ability to explain the data using Akaike information criterion (AIC). Results : Each definition provided very different estimates for the prevalence of the U.S. population that is considered "rural" (e.g., 5.9% for the OMB, 17.0% for the Census Bureau). The OMB definition was most sensitive at detecting urban/rural differences, followed by the Isolation scale. Both these measures use strict, less-inclusive criteria for what constitutes "rural." Conclusions : Overall, results demonstrate the heterogeneity across urban/rural measures. Although findings do not provide a definitive answer for which urban/rural definition is the best for examining rural tobacco use, they do suggest that the OMB and Isolation measures may be most sensitive to detecting many types of urban/rural tobacco-related disparities. Caveats and implications of these findings for rural tobacco use disparities research are discussed. Efforts such as these to better understand which rural measure is appropriate for which situation can improve the precision of rural substance use research.

Researchers have proposed numerous factors that may contribute to rural adolescents' heightened risk for tobacco use. Some of these include well-known risk factors for tobacco use, whereas others concern factors unique to rural populations, reflecting norms and values ("rural culture") that accept and encourage tobacco use. This study aimed to test a broad range of tobacco-use risk factors to determine which were a) universal risk factors for both urban and rural adolescents vs. b) unique risk factors for rural adolescents. Data came from a prospective cohort study of 1220 adolescent males in Ohio who were aged 11-16 (average = 14 years) when surveyed at baseline (2015-2016). Follow-up surveys occurred every 6 months. The present study examined tobacco-use outcomes-prevalent use and incident use-by the two-year follow-up (2017-2018). Findings indicated a higher prevalence of ever-use of cigarette and smokeless tobacco among rural, vs. urban, adolescents at baseline. By the two-year follow-up, the urban/rural difference was attenuated but remained. Stratified multivariable logistic regression indicated that some baseline risk factors were associated with subsequent tobacco use for both rural and urban adolescents. Having an adult tobacco user in the home (for prevalent use) and susceptibility to a male family member offer of tobacco products (for both prevalent and incident use) were associated with tobacco use only for rural adolescents. These findings align with qualitative work demonstrating that masculinity and an intergenerational tobacco culture are important to male adolescents. This unique rural profile should be considered when developing prevention efforts., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Objectives: Health warning messages could be an effective means of communicating the health risks associated with waterpipe (WP) smoking. The objective of this study was to select a message that conveyed the risks associated with WP smoking., Methods: A mixed-methods approach was used to explore the effectiveness of the Food and Drug Administration's (FDA's) mandated message, and others, among young adults using focus groups and surveys. Two focus group studies and one convenience survey were conducted to examine the FDA's mandated message and 11 other WP warning messages. The final study, conducted with a random sample of first-year university students, examined the effectiveness and reactance of the chosen message using previously validated items (scored on a 1-5 scale)., Results: The FDA's mandated message did not resonate well with focus group participants. In the random sample of students, the top message ( WARNING: Hookah smoke contains poisons that cause lung and oral cancers ) had high effectiveness (M = 4.49) and a low reactance (M = 2.12)., Conclusions: Our studies suggest that other messages are more effective for communicating the risks associated with WP smoking than the FDA's message for WP tobacco., Competing Interests: Conflict of Interest Disclosure Statement No conflicts to report.

Objective: There has been a growth in popularity of hookah (or waterpipes) among American college students, despite the health risks. This study investigated factors that predict hookah susceptibility and whether hookah susceptibility predicts hookah initiation and continued use., Method: The study established a cohort of 529 incoming college freshmen (51.6% female) who completed an online survey approximately 1 week before their arrival to a large U.S. university. Students were sent four follow-up surveys throughout the 2016-2017 academic year; 90.5% completed at least one follow-up survey., Results: A total of 13.2% of the sample had used hookah at baseline and 9.9% initiated hookah use over the course of their freshman year. Among the nonusers who had no hookah susceptibility at baseline, 30.0% came to indicate some susceptibility. Multivariable logistic regression indicated that the personality construct conscientiousness was protective against becoming susceptible, whereas coming from a rural part of the state was a risk factor. Susceptibility predicted both continued use among the baseline ever-users and initiation among the baseline never-users., Conclusions: These findings highlight the role of susceptibility in the trajectory of hookah use among U.S. college students.

Working with research animals exposes employees to emotionally demanding work and moral stressors. The emotional impact of animal research is similar to that of working with human patients, and is similarly associated with burnout (BNO) or compassion fatigue (CF), which can lead to psychosomatic symptoms, pervasive states of stress, workplace conflict, and at its most extreme, suicidal ideation. One remedy for such feelings is increasing the satisfaction one feels from performing one's job well, known as compassion satisfaction (Csat). To address these occupational health concerns in an academic research setting, the Ohio State University's Lab Animal Resources (ULAR) study team reviewed existing preventative programing both internal and external to the university. Subsequently, a survey was distributed to all staff members to assess the following factors: employee awareness of free resources already available to them, association between staff demographics and the experience of BNO and/or CF, and the employee's own mitigation recommendations. Respondents were mostly female, in 20 to 49 age range, with 0 to 4 y in the field. Of those responding, 81.6% specified that they had experienced BNO and CF alone, together, or in combination with CSat. Factors statistically associated ( P < 0.05) with BNO and CF were age, number of years in the field, and number of animals euthanized per year. A relative risk analysis was also used to identify protective factors. Only the age of respondents appeared to be a protective factor- the 50+ age group had 88.57% (RR = 0.1143) reduction in risk for experiencing BNO and/or CF. Participant suggestions indicated that employees would like improvements to the work environment, more novel work experiences, and more positive feedback from department leadership. The social ecological model, a public health model for program interventions, was used as a framework for the development of recommendations to mitigate BNO and CF while increasing CSat. The recommendations were customized for ULAR employees based on the survey findings.

The prevalence of smoking among rural Americans and Americans of lower socioeconomic status (SES) remains higher than among their urban and higher SES counterparts. Potential factors contributing to these disparities are area-based differences in the retail environment and tobacco control policies. We describe the association between neighborhood demographics and cigarette prices in rural and urban areas. Prices of one pack of Marlboro Reds, Newport menthols, and the cheapest cigarettes in the store were recorded from a stratified random sample of tobacco retailers in urban (N = 104) and rural (N = 109) Ohio in 2016. Associations between prices and census tract demographics (SES and race) were modeled separately in each region, controlling for store type. In the rural region, as the census tract income increased, the price of Marlboro and Newport cigarettes decreased, and the price of the cheapest pack of cigarettes increased. In the urban region, as the census tract income and percentage of White non-Hispanic people increased, the price of Marlboro decreased; there were no associations between census tract characteristics and the price of Newports or the cheapest cigarettes. Results describe a complex association between cigarette brand, prices, and area characteristics, where the cheapest brands of cigarettes can be obtained for the lowest prices in lower SES rural areas. Tobacco control policies that raise the price of cheap cigarettes, particularly minimum price laws, have the potential to reduce SES-related smoking disparities in both rural and urban populations.

Background: Poor dental health is a common chronic condition among youth. Appalachian versus metropolitan residence, socioeconomic status, and health behaviors contribute to poor dental health. Limited research has directly compared dental health and risk factors for poor dental health among Appalachian and metropolitan youth. We examined the association between dental health and residence among adolescent boys and explored socioeconomic and behavioral factors that may contribute to differences in dental health., Methods: Adolescent males from metropolitan and rural Appalachian Ohio (n = 1220, age 11-16 years) reported their diet and tobacco use. Parents or guardians reported when boys had last visited the dentist and rated their dental health (excellent/very good/good versus fair/poor). Unadjusted logistic regression modeled the association between fair/poor dental health and residence (metropolitan versus Appalachian). Adjusted analyses controlled for race, household income, dental visits, diet, and tobacco use., Results: Appalachian (versus metropolitan) boys were more likely to have used tobacco in the past 30 days and consumed fewer fruit and vegetables, more added sugar, and more sugary beverages. The relation between dental health and Appalachian versus metropolitan residence did not reach statistical significance, and adjusting for behavioral factors did little to change the observed association., Conclusion: Our findings suggest that some of the urban/rural disparities in dental health observed in other studies may be related to behavioral factors like tobacco use and diet, but much remains unexplained. We provide support for behavioral interventions to address these issues in the Appalachian community.

Background: Human papillomavirus (HPV) vaccine has been recommended for males in the United States since 2011, yet little is known about vaccine coverage among adolescent males in Ohio. Our longitudinal study examined HPV vaccine coverage among adolescent males in Ohio and identified predictors of vaccination., Methods: The Buckeye Teen Health Study recruited adolescent males ages 11-16 and their parents from one urban county and nine rural counties in Ohio. We report longitudinal vaccination data on 1126 adolescent males, with baseline data from 2015-2016 and follow-up data from 2017-2018. We used multivariable Poisson regression to identify predictors of HPV vaccine initiation that occurred between baseline and follow-up., Results: At baseline, 42.4% of parents reported their sons had initiated the HPV vaccine series. Among parents whose sons were unvaccinated at baseline, 36.3% indicated initiation at follow-up. Initiation at follow-up was more common among sons who had received influenza vaccine (RR = 1.54, 95% CI = 1.08-2.18) or whose parents indicated lack of a recent visit to a doctor as the main reason for not yet vaccinating at baseline (RR = 1.41, 95% CI = 1.02-1.95). Initiation was less common among sons whose parents had an associate's degree or some college education (RR = 0.28, 95% CI = 0.46-0.99). Main reasons for not vaccinating changed from baseline to follow-up among parents of unvaccinated sons., Conclusions: Although HPV vaccine initiation increased over time, many adolescent males in Ohio remain unvaccinated. Findings can help guide future strategies for increasing HPV vaccine coverage among this population.

Objective: Blu's 'Something Better' advertising campaign ran in popular print magazines in 2017. The campaign included advertisements with fake warnings conveying positive messages, which mimicked the Food and Drug Administration (FDA)'s warning requirements for electronic cigarette (e-cigarette) advertisements that took effect in 2018. We report adolescent males' recall of these fake warnings and how exposure to fake warnings affected recall of other advertisement components, including the actual warning or health risks, brand and product., Methods: Ohio males ages 12-19 years (N = 775; 73.8 % white non-Hispanic) were randomly assigned to view an e-cigarette advertisement with or without a fake warning. Afterward, they were asked what they remembered most about the advertisement. Responses were qualitatively coded. Statistical analyses included survey-weighted descriptive statistics and logistic regression., Results: Of participants who viewed an e-cigarette advertisement with a fake warning, 27.0 % reported the fake warning was what they remembered most, and 18.8 % repeated the fake warning message. Participants viewing advertisements with a fake warning had lower odds of recalling the actual warning or health risks (OR = 0.29; 95% CI: 0.11 to 0.77) or brand (OR = 0.43; 95% CI: 0.22 to 0.85), compared with participants viewing other e-cigarette advertisements., Conclusions: Adolescents viewing an advertisement with a fake warning were less likely to recall the advertisement's actual warning or health risks. Although e-cigarette advertisements now carry large FDA-mandated warnings, this tactic could be used for cigarette advertisements that continue to carry small warnings in the USA. Findings underscore the necessity of tobacco advertisement surveillance and study of advertisements' effects on adolescents., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Objectives. To conduct a content analysis of news articles to investigate the relationship between language used to describe e-cigarettes, how the news articles framed (conveyed information to influence a certain perception of the news read by its audience) e-cigarettes, and the Food and Drug Administration's (FDA's) oversight of e-cigarettes. Methods. We searched a database of articles published across the United States from February 1, 2016, to February 28, 2017, using the headline terms "e-cigarette," "e-cig," and "vape." We then dichotomized terms into 2 categories: technical ("e-cigarette" or "e-cig") and nontechnical ("vape"). We coded the frame of each article body as positive, negative, or neutral or mixed. Results. Articles containing the term "vape" in the headline were more likely to positively frame e-cigarettes ( P  ≤ .001) and negatively frame FDA oversight ( P  ≤ .001) in the body than were those with "e-cigarette" or "e-cig" in the headline. Conclusions. Omitting the word "cigarette" when describing tobacco products may reduce the negative perception associated with tobacco use, making it more appealing. It is important to know which terms are used to describe e-cigarettes and how these terms can make those products appear less harmful.

Purpose: In autumn 2017, Columbus, Ohio, joined numerous other US locations in raising their legal sales age for purchasing tobacco to 21 (ie, becoming "T21"). The present study sought to establish a baseline for ID checks in Columbus prior to T21 enforcement and to examine whether store type and marketing were associated with better rates of ID checks., Design: Fieldworkers aged 20 to 21 years visited a random sample of 110 tobacco retailers during summer 2017 (drawn from >10 000 licensed retailers in the county). After collecting store-related information, they attempted to purchase cigarettes and recorded whether their ID was checked (federal law requires ID checks for anyone who looks younger than 27 years)., Setting: Columbus, Ohio., Measures: Store type, external tobacco advertising, and ID check outcome., Analysis: Descriptive and inferential statistics., Results: Among stores where cigarettes were purchased, 61.1% did not conduct ID checks. Absent ID checks were associated with the store being a convenience store or tobacco shop, χ 2 (2) = 4.45, P = .035, and having a greater amount of external advertising, t (93) = 2.00, P = .049., Conclusion: Overall, the low rate of ID checks for young adults purchasing tobacco in Columbus is concerning. Continued monitoring of retailer compliance will be important as retailers adjust to the arrival of T21. Targeted enforcement and additional outreach with tobacco shops, convenience stores, and stores with a high amount of external advertising may be particularly needed.

Objectives: The tobacco industry has a history of making "natural" claims in advertisements. We report how viewing advertisements with such claims affected what adolescents found memorable., Methods: Adolescent boys (N = 1220; 11-16 years old) were randomly assigned to view a Natural American Spirit (NAS) or other brand cigarette advertisement, and were asked what they remembered about the advertisement. Survey-weighted logistic regression models assessed whether memorability of advertisement components differed by NAS advertisement exposure., Results: Adolescents viewing a NAS advertisement (vs another brand) had lower odds of finding memorable the advertisement's warning (OR = 0.58; 95% CI: [0.34, 0.98]) or brand (OR = 0.25; 95% CI: [0.11, 0.54]). They had higher odds of mentioning tobacco (OR = 2.33; 95% CI: [1.49, 3.63]) and packaging (OR = 2.57; 95% CI: [1.51, 4.37]). An estimated 6.7% of those viewing an NAS advertisement said the product was not addictive., Conclusions: Reduced-harm claims on cigarette advertisements may affect what adolescents find salient about the advertisement. As the FDA's agreement with Santa Fe Natural Tobacco Company to remove these claims is not inclusive of all reduced-harm claims and does not apply to other companies, findings underscore the need for prohibiting all reduced-harm claims from cigarette advertisements., Competing Interests: Conflict of Interest Statement All authors have no conflicts of interest to disclose.

Introduction: Studies from various parts of the country suggest that tobacco-related health disparities are exacerbated by disparities in the distribution of tobacco retailers (convenience stores, tobacco shops, etc.). The purpose of the present study was to use advanced spatial modeling techniques for count data to estimate current disparities in tobacco retailer density in Ohio., Methods: We identified and geocoded 11,392 tobacco retailers in Ohio. Next, we obtained census tract-level information on race/ethnicity, poverty, and age and obtained county-level information on whether an area was Urban, Suburban, or Rural. Finally, we used negative binomial generalized linear models, adapted for residual spatial dependence, to determine the association between per capita tobacco retailer density and demographic characteristics-summarized by adjusted rate ratios., Results: There were more (from 1.4-1.9 times as many) retailers per capita in high-poverty, vs. low-poverty tracts. Poverty also interacted with age: the association between high poverty and high retailer density was stronger for tracts with a low youth population. Density was also greater in tracts with a high (vs. low) prevalence of African Americans (1.1 times as many) and Hispanics (1.2 times as many). Finally, density was generally greater in rural (vs. suburban or urban) tracts, although the effect was modified by a three-way interaction: density was particularly high for rural tracts that also had both a high prevalence of poverty and a low youth population., Discussion: Overall, our findings indicate that Ohio's vulnerable populations are exposed to a greater per capita density of tobacco retailers., Public Health Implications: There is a need for state and local-level tobacco control policies that will improve equity and reduce health disparities.

Purpose: Research indicates that tobacco marketing contributes to higher pro-tobacco attitudes and behaviors among adolescents, but no studies have been able to assess the impact of real-world tobacco marketing exposures in real-time. The purpose of this study was to examine the magnitude and impact of tobacco marketing exposure on adolescents using ecological momentary assessment (EMA). Our primary hypotheses were that (1) youth would most frequently report tobacco marketing at the retail points-of-sale and (2) greater exposures to tobacco marketing would be associated with more favorable tobacco-related attitudes, use, and expectancies., Methods: Participants were adolescent males from rural and urban Ohio (N = 176, ages 11-16). For ten days, these adolescents were prompted at two-three random times/day to complete a brief smartphone-based survey about their exposures and responses to tobacco-related advertising., Results: Adolescents reported exposures to tobacco marketing an average of 1.9 times over the 10-day EMA period, with over 10% seeing a tobacco advertisement 5 or more times. Reports of marketing exposures occurred most frequently at the point-of-sale; exposures were higher among tobacco users and rural adolescents. Consistent with hypotheses, marketing exposure was related to more positive attitudes to the tobacco advertisements, more tobacco use, and higher expectancies to use in the future., Conclusions: Overall, these findings signal the magnitude of tobacco marketing exposures and their pernicious impact on youth. Findings underscore the importance of federal, state, and local-level tobacco regulatory policies to protect youth from the marketing that puts them at risk for a lifetime of nicotine addiction and tobacco-related diseases., (Copyright © 2018 Elsevier Ltd.

Objectives: This study aimed to better examine substance use among college students during the acute period of transition between high school and college., Methods: One week before coming to campus, participants completed an online survey assessing their alcohol, tobacco, and marijuana use. Next, beginning on the first Friday of the semester, they completed a 10-day experience sampling (ES) protocol, receiving one app-based survey each morning assessing recent substance use., Results: Among students who used any tobacco product prior to college, 70% or more reported alcohol use during ES. Among previous marijuana users, 85.7% reported alcohol use during ES. Baseline alcohol and tobacco use were not associated with subsequent marijuana use., Conclusions: Substance use prevention should target the transition to college., Competing Interests: Conflict of Interest Statement: The authors declare no conflicts of interest.

Background: The tobacco industry spends billions on retail marketing and such marketing is associated with tobacco use. Previous research has not examined actual and potential exposures that adolescents have on a daily basis., Objective: The objective of this study was to determine whether both self-reported and geographically estimated tobacco retailer exposures differ by participant or neighborhood characteristics among urban and rural adolescents., Methods: The data for this study were part of a cohort study of 1220 adolescent males residing in urban and rural (Appalachian) regions in Ohio. The baseline survey asked participants how often they visited stores that typically sell tobacco in the past week (self-reported exposures). The number of tobacco retailers between home and school was determined using ArcGIS software (potential exposures). Adjusted regression models were fit to determine the characteristics that were associated with self-reported or potential exposures to retailers., Results: Adolescents who were non-Hispanic black or other racial/ethnic minority, had used tobacco in the past, and lived in rural areas had higher self-reported exposures. Urban adolescents, non-Hispanic black or other racial/ethnic minority, and those living in neighborhoods with a higher percentage of poverty had more potential exposures to tobacco retailers in their path between home and school., Conclusions: Rural adolescents had more self-reported marketing exposures than urban adolescents. However, urban adolescents had more potential tobacco exposures between home and school. Thus, point of sale marketing limitations might be a more effective policy intervention in rural areas whereas limits on tobacco retailers might be more effective for urban areas.

This study examined quit rates longitudinally for cigarettes, e-cigarettes, hookah, cigars, and all tobacco products in a U.S. national sample of women aged 18-44 who completed both Wave 1 (W1) and Wave 2 (W2) of the Population Assessment of Tobacco and Health (PATH, 2013-2014, 2014-2015) study (N = 7814). Quit rates were examined among women who transitioned into pregnancy across survey waves, and among a comparable sample of non-pregnant women to provide contextual information about quitting among the broader population of reproductive-aged women. Multiple logistic regression modeling was used to estimate the associations of pregnancy and quitting adjusting for other demographic and psychosocial characteristics. Quit rates among women who were pregnant in W2 were highest for hookah (98.3%), followed by cigars (88.0%), e-cigarettes (81.3%), and lowest for tobacco cigarettes (53.4%). Slightly more than half (58.7%) of women reported quitting use all tobacco products while pregnant. Pregnancy was independently associated with increased odds of quitting hookah (AOR = 52.9, 95%CI = 3.4, 830.2), e-cigarettes (AOR = 21.0, 95%CI = 2.6, 170.3), all tobacco products (AOR = 9.6, 95%CI = 6.4, 14.5), and cigarettes (AOR = 6.5, 95%CI = 4.2, 10.1), although not cigars. Relative to other demographic and psychosocial characteristics, pregnancy was the strongest predictor of quitting use of each tobacco product. While these data indicate that pregnancy has strong, independent associations with quitting a variety of commercially available tobacco products, the comparatively lower quit rates for cigarettes versus other tobacco products underscores the long-standing need for more intensive, multipronged clinical and regulatory interventions to reduce cigarette use among reproductive-aged women., (Copyright © 2018 Elsevier Inc.

This study examined prevalence and correlates of using cigarettes, e-cigarettes, and other tobacco/nicotine delivery products in a U.S. national sample of women of reproductive age. Weighted data were obtained from women aged 15-44 years who were not currently pregnant in the first wave of the Population Assessment of Health and Tobacco (PATH, 2013-2014) study (N = 12,848). 20.1% of women were current cigarette smokers, 5.9% current e-cigarette users, 4.9% current cigar smokers, and 6.5% current hookah users. Prevalence of current use of other tobacco products was <1.0%. Current cigarette smoking was the strongest correlate of current e-cigarette use (OR = 65.7, 95% CI = 44.8-96.5), cigar smoking (OR = 19.2, 95% CI = 14.1-26.1), and hookah use (OR = 6.6, 95% CI = 5.1-8.5). Among former cigarette smokers, 3.8%, 6.9%, and 3.2% were also currently using e-cigarettes, hookah, and cigars, respectively. Use of other tobacco and nicotine delivery products was low among those who never smoked tobacco cigarettes: 2.5% used hookah and <1.0% used other products. Cigarette smoking prevalence remains relatively high among women of reproductive age and strongly correlated with use of other tobacco products. Monitoring tobacco and nicotine use in this population is important due to the additional risk of adverse health impacts should they become pregnant. Clinicians working with cigarette smokers should assess for use of other tobacco products. Among women of reproductive age, use of emerging tobacco and nicotine products appears to be largely, although not exclusively, restricted to current cigarette smokers., (Copyright © 2018 Elsevier Inc.

: media-1vid110.1542/5839992833001PEDS-VA&#95;2018-1505 Video Abstract BACKGROUND: Researchers in several studies have examined correlations between tobacco harm perceptions and tobacco use in youth, but none have prospectively addressed the association between harm perceptions and subsequent new use across multiple noncigarette products., Methods: Product-specific absolute and relative harm perceptions for cigarettes, electronic cigarettes (e-cigarettes), cigars, pipes, hookah, and smokeless tobacco were collected at wave 1 (W1) (2013-2014) among youth in the nationally representative US Population Assessment of Tobacco and Health Study (12-17 years of age; n = 10 081). At wave 2 (W2) (2014-2015), product-specific new use was calculated. Adjusted relative risks were used to estimate if harm perceptions at W1 predicted W2 new tobacco use., Results: The proportion of youth who endorsed "a lot of harm" was highest for cigarettes (84.8%) and lowest for e-cigarettes (26.6%); the proportion of youth who thought products were "more harmful" than cigarettes was highest for cigars (30.6%) and lowest for e-cigarettes (5.1%). Among youth who had not used those products at W1, product-specific new use at W2 ranged from 9.1% (e-cigarettes) to 0.6% (pipes). Youth who believed that noncombustible tobacco products posed "no or little harm" at W1 were more likely to have tried those products at W2 ( P < .05). Youth who viewed e-cigarettes, hookah, and smokeless tobacco as "less harmful" than cigarettes at W1 were more likely to try those tobacco products at W2 ( P < .05)., Conclusions: Low harm perceptions of noncigarette tobacco products predict new use of these products by youth within the next year. Targeting product-specific harm perceptions may prevent new tobacco use among youth., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2018 by the American Academy of Pediatrics.)

Smoking status following cardiac events strongly predicts future morbidity and mortality. Using a nationally representative sample of United States adults, aims of this study were (1) to estimate use of, and attitudes towards, tobacco products as a function of level of cardiac risk, and (2) to explore changes in attitudes and tobacco use among adults experiencing a recent myocardial infarction (MI). Data were obtained from the first and second waves of the Population Assessment of Tobacco and Health (PATH) study. Use and attitudes towards tobacco products were examined at Wave 1 among adults with no chronic health condition (n = 18,026), those with risk factors for heart disease (n = 4593), and those who reported ever having had an MI (n = 643). Changes in perceived risk of tobacco and use between the two waves and having an MI in the last 12 months (n = 240) were also examined. Those who reported lifetime MI were more likely to believe that smoking/using tobacco was causing/worsening a health problem. Having had a recent MI event increased perceived tobacco-related risk and attempts at reduction/quitting, but did not significantly impact combusted tobacco cessation/reduction or uptake of non-combusted tobacco products. Sociodemographic characteristics and use of other tobacco products were associated with change in use of tobacco products. Those who have an MI are sensitized to the harm of continued smoking. Nonetheless, having an MI does not predict quitting combusted tobacco use or switching to potentially reduced harm products. Intense intervention is necessary to reduce combusted use in this high-risk population., (Copyright © 2018 Elsevier Inc. All rights reserved.)
