Abstract	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 ( 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.

Abstract	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 (

Abstract	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.

Article ; Online: Tobacco 21's Impact Amid the E-Cigarette Surge.

Roberts, Megan E / Keller-Hamilton, Brittney / Teferra, Andreas A

Abstract	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.

Abstract	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.

Abstract	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.

Abstract	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.

Abstract	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.

Abstract	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.
