Devin McCauley earned his PhD in Human Development and Family Studies from The Pennsylvania State University in 2021, where his research investigated family, school, and peer influences on adolescent mental health and well-being. His research also applies a developmental framework to evaluate risk factors associated with adolescent e-cigarette use. His goal is to inform, develop, and evaluate family and school-based prevention programs which support healthy adolescent development and mitigate e-cigarette use.

  • Adolescents, Young Adults, and Adults Continue to Use E-Cigarette Devices and Flavors Two Years after FDA Discretionary Enforcement. International journal of environmental research and public health McCauley, D. M., Gaiha, S. M., Lempert, L. K., Halpern-Felsher, B. 2022; 19 (14)


    This study assesses the use of e-cigarette devices and flavors using a large, cross-sectional survey of adolescents, young adults, and adults (N = 6131; ages 13-40 years old; Mage = 21.9) conducted from November to December 2021, 22 months after the FDA announced its prioritized enforcement policy against some flavored pod/cartridge-based e-cigarettes. We analyzed the patterns of use by age group: adolescents and young adults (AYAs) under 21 (minimum age of e-cigarette sales), young adults (21-24 years old), and adults (25-40 years old). The participants reported using e-cigarettes ever (44.2% < 21; 67.1% 21-24; 58.0% > 24), in the past 30 days (29.8% < 21; 52.6% 21-24; 43.3% > 24), and in the past 7 days (24.5% < 21; 43.9% 21-24; 36.5% > 24). Disposables were the most used e-cigarette device type across age groups (39.1% < 21; 36.9% 21-24; 34.5% > 24). Fruit, sweet, mint, and menthol flavors were popular across age groups; however, chi-squared tests for trends in proportions revealed age-related trends in past 30-day flavor use by device type. Findings suggest current AYA e-cigarette use may be higher than recorded by the NYTS 2021. The FDA, states, and localities should adopt more comprehensive restrictions on flavored e-cigarette products in order to reduce adolescent and young adult e-cigarette use.
