Young Adults’ Vaping, Readiness to Quit, and Recent Quit Attempts: The Role of Co-use With Cigarettes and Marijuana.

Introduction:
This text provides an analysis of a study examining the relationship between e-cigarette use and other substance use among young adults. The study focuses on e-cigarette user profiles and their correlation with readiness to quit e-cigarette use and past-year e-cigarette quit attempts. The study also aims to identify sociodemographic and e-cigarette use characteristics associated with various e-cigarette user profiles.

Key Points:

* The study uses data from the VAPES study, a five-wave longitudinal cohort study of young adults in six metropolitan statistical areas.
* Participants were recruited through social media and were eligible if they were 18-34 years old, lived in one of the six MSAs, and spoke English.
* The study focuses on past 30-day e-cigarette users and categorizes them into four user profiles: e-cigarette only, e-cigarette/other tobacco, e-cigarette/marijuana, and e-cigarette/other tobacco/marijuana.
* Multilevel multinomial logistic regression was used to characterize the polyuser profiles relative to e-cigarette only users.
* Bivariate analyses and multilevel regression analyses were conducted to examine correlates of readiness to quit e-cigarettes in the next 6 months and past-year e-cigarette quit attempts.
* The study found that e-cigarette/other tobacco dual users were more likely to be male and older, while e-cigarette/marijuana dual users were more likely to use high-nicotine e-liquids and closed systems.
* E-cigarette/other tobacco/marijuana polyuse was associated with being sexual minority and using high-nicotine e-liquids.
* Readiness to quit e-cigarettes in the next 6 months was reported by 20.8%, while past-year e-cigarette quit attempts were reported by 32.3%.

Main Message:
The study highlights the importance of understanding e-cigarette user profiles and their correlation with readiness to quit e-cigarette use and past-year e-cigarette quit attempts. The findings suggest that certain user profiles, such as e-cigarette/other tobacco dual users and e-cigarette/other tobacco/marijuana polyusers, may be more likely to use high-nicotine e-liquids and may require targeted interventions to promote cessation. Additionally, the study underscores the need for further research to understand the relationship between e-cigarette use and other substance use among young adults.
