This study assessed adolescents' harm and addiction perceptions of the highest-selling brand-JUUL-of the most commonly used tobacco product-electronic cigarettes (e-cigarettes)-among adolescents in the United States. ⋯ The study reports adolescents' perceptions of the harmfulness and addictiveness of the highest-selling brand of the most commonly used tobacco product among youth in the United States. Though the majority of adolescents correctly believed that using a JUUL e-cigarette would put them at, at least, some risk for experiencing health problems and addiction, a small proportion believed that using a JUUL e-cigarette would be risk free. Correcting such risk-free perceptions may reduce adolescents' interest in trying and continuing to use JUUL e-cigarettes.

E-cigarette Dependence Measures in Dual Users: Reliability and Relations With Dependence Criteria and E-cigarette Cessation.
Electronic cigarettes (e-cigarettes) have drastically changed the nicotine and tobacco product landscape. However, their potential public health impact is still unclear. A reliable and valid measure of e-cigarette dependence would likely advance assessment and prognostication of the public health impact of e-cigarettes. The aim of this research was to examine the internal consistency, structure, and validity of three e-cigarette dependence scales. ⋯ This research provides empirical support for three e-cigarette dependence measures: the e-FTCD, the PS-ECDI, and the e-WISDM among dual users of e-cigarettes and combustible cigarettes. The PS-ECDI and e-WISDM are more reliable, but all three measures were strongly correlated with key dependence constructs such as heavy use and continued use over time.

Electronic cigarette (ECIG) use and changes in cigarette smoking status may be influenced by self-reported reasons for using ECIGs. ⋯ Given that certain reasons for ECIG use, such as using ECIGs in locations are where smoking is not allowed, may inhibit smoking reduction, policies may be developed to prevent ECIG use in locations where smoking is banned. In addition, because certain reasons for ECIG use may aid in relapse prevention, such as availability of desired flavors, efforts should be made to identify ECIG device characteristics that are appealing to smokers but not youth or nontobacco users. These results provide support for future research on reasons for ECIG use to inform regulatory policies.

JUUL has emerged as the leading brand in a rapidly evolving electronic cigarette (e-cigarette) market. JUUL is distinctive for its novel nicotine delivery method that results in high nicotine concentrations, as well as its sleek, discreet design. This study examined national estimates of JUUL among youth in the United States, including whether JUUL users report different patterns of use compared to users of other e-cigarettes. ⋯ This study examined national estimates of JUUL e-cigarette use among youth in the United States, during the early phase of JUUL's popularity. JUUL was among the most popular e-cigarette brands among youth, and there were few differences in sociodemographic profile or patterns of use between JUUL and other e-cigarette brands. The findings help to characterize the rapid rise of this new product category within the rapidly evolving e-cigarette market at a time when the US Food and Drug Administration and public health community are seeking to understand JUUL and its appeal among young people.

Although some smokers switch to exclusive use of electronic cigarettes (e-cigarettes), others become dual users of combustible cigarettes and e-cigarettes. Little is known about how the onset of vaping affects the use of and dependence on combustible cigarettes or total nicotine use and dependence, which may influence health-related and cessation outcomes. Using self-report data of current combustible and e-cigarette use and retrospective recall of pre-vaping smoking in a sample of dual users, the aims of this study were (1) to compare pre- and post-vaping number of cigarettes per day and combustible cigarette dependence; (2) to compare pre- and post-vaping total nicotine use frequency (number of vaping sessions and cigarettes smoked per day), and total nicotine dependence; and (3) to examine predictors of nicotine dependence. ⋯ In dual users, a reduction in smoking following onset of vaping may offer some harm reduction via reduction in cigarette intake. However, the increase in total nicotine use and dependence could affect the ability to quit either or both products.
