    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 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.

    Abstract 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 < .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.

    Abstract 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.

    Abstract 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.
