Potential risk factors for cigarette use among a sample of college JUUL users.

Objective: To examine the relationship between demographics, other tobacco use, and JUUL dependency on combustible cigarette use among college JUUL users. Participants: Undergraduates (n = 595) at a large southwestern university who used JUUL weekly completed a cross-sectional online survey in March 2019. Methods: Logistic regressions examined associations between covariates and ever use/past 30-day use of cigarettes. Results: As age increased, odds of ever trying a cigarette increased (AOR = 1.87; 95% CI = 1.45-2.41); however, as age of JUUL initiation increased, odds of ever (AOR = 0.80; 95% CI = 0.65-0.99) or past 30-day (AOR = 0.78; 95% CI = 0.63-0.97) cigarette use decreased. Those moderately (AOR = 2.03; 95% CI = 1.07-3.82) or highly (AOR = 8.01; 95% CI = 3.08-20.83) dependent on JUUL were more likely to have tried cigarettes than those not dependent. However, dependence was not associated with past 30-day use. Conclusions: JUUL users may not transition to combustible cigarettes during college. Longitudinal studies are needed to examine transitions in JUUL users' tobacco product use after college.

College Students' Reasons for Using JUULs.

PURPOSE: To identify reasons that college students use JUUL and explore associations between reasons for using JUUL and social and behavioral (tobacco use) factors. DESIGN: On-line, cross-sectional survey. SETTING: Large southwestern university in the US. SUBJECTS: Undergraduate students (n = 605) who owned JUUL and used it weekly. MEASURES: The study measured age of JUUL initiation, JUUL dependence, and use of other e-cigarettes and other tobacco products. Participants described reasons for JUUL use as brief open-ended responses. ANALYSIS: Responses were categorized by 2 researchers using an inductive procedure. Logistic regressions examined associations between demographics and use frequency and categorized reasons for using JUUL. RESULTS: Four reasons for using JUUL emerged: self-help (48.4%), social (30.4%), experience (42.8%), and substance use/addiction (42.3%). Daily JUUL users were 1.66 (95% CI: 1.05-2.63) times as likely to use JUUL for self-help than those who used JUUL 1-3 days/week. Those who had never tried a cigarette were twice (OR = 2.08; 95% CI: 1.22-3.54) as likely as cigarette-first users to use JUUL for social reasons. Males (OR = 1.87; 95% CI: 1.32-2.65) had higher odds of using JUUL for the experience than females, and JUUL and other e-cigarettes users were 4.37 (95% CI: 1.83-10.45) times as likely as JUUL-only users to use JUUL due to substance use/addiction. CONCLUSION: JUUL users report unique reasons for use (e.g., addiction) not previously reported for older models of e-cigarette devices.

Tobacco 21 Policies in the U.S.: The Importance of Local Control With Federal Policy.

INTRODUCTION: In December 2019, the U.S. raised the minimum legal sales age of tobacco to 21 years, a law commonly known as Tobacco 21. This study examines local Tobacco 21 policies for the inclusion of model policy components: comprehensive tobacco definition, age verification and tobacco access, enforcement measures, tobacco retail license, and violation penalties. METHODS: A document analysis of Tobacco 21 local policies passed in the U.S. before July 1, 2019 (N=477) was conducted in May 2020 using a Tobacco 21 policy assessment tool. Policies were coded by 2 independent coders for the inclusion of components. RESULTS: Many localities included model component: comprehensive tobacco definition (65%), appearance age (70.9%), local tobacco retail license (72%), a graduated monetary penalty structure (93%), and tobacco retail license suspensions or revocations (74%) for repeated violations. However, only 17.4% of policies included an appearance age in compliance with federal law (30 years). Furthermore, few policies included enforcement components, such as a mandatory number of inspections (5.9%) or compliance checks (6.7%) per year, or a minimum age for the underage purchasers used during compliance checks (8.4%). CONCLUSIONS: Local policies can play an important role in tobacco control by providing an added layer to ensure adequate enforcement of age-restriction policies and allow an avenue to introduce strict measures that may diffuse into higher branches of government for policy adoption. Although many local Tobacco 21 policies fill regulatory gaps within the state and federal laws, often there is a lack of model components to ensure that policies are implemented as intended.

Addiction vs. dependence: A mixed methods analysis of young adult JUUL users.

OBJECTIVE: JUUL-brand electronic cigarettes (e-cigarettes) contain higher levels of nicotine than other e-cigarettes. The current study examined the relationship between young adults' self-reported addiction and measured JUUL dependence. METHODS: This study used a sequential, explanatory mixed methods design. Data were collected from a large, southwestern college in the US. College students who were weekly JUUL users and owned a JUUL device (n = 595) completed a cross-sectional online survey, then a subsample (n = 51) participated in in-person interviews. All data were collected between March-April 2019. T-tests were used to examine differences between JUUL dependence and self-reported addiction, and logistic regressions were employed to examine factors that may influence self-reported addiction to JUUL, nicotine, and other e-cigarettes. Interviews were independently coded by 2 coders (kappa ranged from 0.46 to 0.99) then analyzed for corresponding themes. RESULTS: Participants who had a higher JUUL dependence were more likely to report addiction to several substances/products, including nicotine, JUULs, cigarettes, other e-cigarettes, alcohol, and marijuana. Interview participants minimized JUUL addiction by comparing JUUL to other socially acceptable addictions and describing JUUL addiction as a habit. Interview participants suggested addiction to nicotine was more stigmatizing than JUUL. The number of days participants used JUUL per week, use of traditional tobacco products, and measured JUUL dependence were each associated with self-reported JUUL addiction. CONCLUSIONS: Social construction of self-reported addictions may be changing young audiences' views of addiction to JUUL. Research is needed to see if using the phrase 'nicotine dependence' rather than 'JUUL addiction' influences young adults' JUUL use.
