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 (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.
Highlights
In the United States, e-cigarette use has increased dramatically over the last few years, among young people
Our analyses further indicated that short-term quit attempts and quit interest were more likely among freshmen than juniors, and less likely among recent cigarillo users than non-users
Our findings suggest the need for policy level actions that address tobacco control among young adult current JUUL users
Summary
In the United States, e-cigarette use has increased dramatically over the last few years, among young people. Past 30-day (current) e-cigarette use surged from 1.5% in 2011 to 19.6% in 2020 among high school students and was their most widely used tobacco product [1,2]. Young adults showed widespread use of e-cigarettes. A recent national survey estimated the prevalence of current e-cigarette use among young adults aged 18–24 years at 7.6%, the highest prevalence compared to all other adult age groups, including middle-aged and older adults [3]. The high prevalence of e-cigarette use was likely precipitated by JUUL, an e-cigarette brand that revolutionized the market with a high-tech design resembling a USB flash drive. In a relatively short period, JUUL comprised over 70% of the e-cigarette market share [4]
