Associations between county-level e-cigarette-inclusive Tobacco 21 law population coverage and e-cigarette use behaviors among United States adolescents in Monitoring the Future.

ABSTRACT:

Background and aims

In the United States (US), Tobacco 21 (T21) laws set the minimum legal sale age for all tobacco products to 21 years. This study aimed to examine whether e-cigarette-inclusive T21 laws were associated with e-cigarette use behaviors and related disparities among US adolescents.

Design

We used nationally representative, repeated cross-sectional Monitoring the Future data to compare self-reported current e-cigarette use (2014-2022) and first e-cigarette initiation (2015-2022) among adolescents in counties with 100% ('full') versus <100% ('partial or no') e-cigarette-inclusive T21 law population coverage using modified Poisson regression, examining differences by sex, race and ethnicity, parental educational attainment and college educational expectations thr
