Summary
Introduction:
This text provides an analysis of patterns of sustained e-cigarette use in a sample of young adults over a two-year period. The study focuses on changes in device type, number of days used, combustible tobacco product use, and symptoms of nicotine dependence.
Key Points:
* The study is based on data from five waves of the Project M-PaCT cohort, and is limited to those reporting past 30-day e-cigarette use at every wave (n = 75).
* Mixed effects regressions were conducted for each dependent variable, controlling for sociodemographic variables.
* among sustained users, the majority reported using a rechargeable device, and the average number of days used was about 2 for disposable devices and 14 for rechargeable devices.
* The odds of combustible tobacco product use decreased over time, while symptoms of e-cigarette nicotine dependence increased over time.
* For both e-cigarette device types, there were no changes in device type or number of days used over time.
Main Message:
This study sheds light on the patterns and changes in e-cigarette use among sustained users over a two-year period. The findings highlight the need for e-cigarette specific dependence measures and the importance of examining more than just the prevalence and correlates of e-cigarette use. The results suggest that nicotine dependence may play an important role in the continued use of e-cigarettes among young adults. Overall, the text provides valuable insights for regulators and policymakers in understanding and addressing the use of e-cigarettes among young adults.
