Socio-temporal contextual and community factors associated with daily exclusive ENDS use and dual use with tobacco cigarettes among adolescent vapers: an ecological momentary assessment study.

Introduction:
This text is a research article that examines the socio-temporal contextual and community factors associated with daily exclusive electronic nicotine delivery systems (ENDS) use and dual use with tobacco cigarettes among adolescent vapers. The study uses ecological momentary assessment (EMA) data collected over 14 days from a sample of 50 adolescent past two-week vapers. The primary analyses are multilevel regressions, accounting for daily observations nested within individuals.

Key Points:

* Participants used ENDS exclusively on 44% of days and dual used ENDS and tobacco cigarettes on 8% of the days.
* Dual use days (versus exclusive ENDS use days) were associated with "vaping because tobacco use was prohibited".
* Dual use days (versus no use days) were associated with greater exposure to adults vaping, peers vaping, and ENDS advertisements or promotions.
* Exclusive use days (versus no use days) were only associated with greater exposure to peers vaping.
* Study findings support stricter regulation of ENDS marketing and for smoke-free air laws that include ENDS.
* The study also supports prioritizing family- and school-based prevention programming that effectively communicates risk associated with ENDS use, including heightened risk of dual use and dependence.

Main Message:
The study highlights the importance of understanding the socio-temporal contextual and community factors associated with adolescent ENDS use and dual use with tobacco cigarettes. Exposure to peers and adults vaping and exposure to ENDS marketing were associated with same-day dual use behaviors. The findings support stricter regulation of ENDS marketing and for smoke-free air laws that include ENDS. Additionally, the study emphasizes the need for family- and school-based prevention programming that effectively communicates the risks associated with ENDS use, including heightened risk of dual use and dependence. The study's findings can inform policies and prevention efforts aimed at reducing the number of adolescents who transition to tobacco cigarette use.
