Sociodemographic differences in use of nicotine, cannabis, and non-nicotine E-cigarette devices

Background: Sociodemographic differences in e-cigarette use have been documented; however, disparities in use of specific e-cigarette types with various ingredients have yet to be thoroughly investigated. This study examines ever-and past-30-day-use of nicotine, cannabis, and non-nicotine e-cigarette device types by sex, sexual orien-tation, race/ethnicity, and financial comfort.Methods: Data were drawn from a 2021 national cross-sectional survey of adolescents, young adults, and adults (N = 6131, ages 13-40 years old). Participants reported ever and past-30-day-use of (1) disposable nicotine e -cigarettes, (2) pod/cartridge-based nicotine e-cigarettes, (3) "other" nicotine e-cigarettes, (4) non-nicotine e -cigarettes, (5) e-cigarettes with THC, and (6) e-cigarettes with CBD. We constructed summary tables for each e -cigarette device type in which percentages of ever and past-30-day-use were calculated by birth year category and sociodemographic variables: (a) sex, (b) sexual orientation, (c) race/ethnicity, and (d) financial comfort.Results: Females born between 1996 and 2008 reported higher rates of past-30-day disposable e-cigarette use relative to males (females 26.4%; males 22.4%). Compared to their heterosexual counterparts, LGBTQ+ par-ticipants reported higher overall rates of past-30-day-use for disposable (LGBTQ+ 27.9%; Heterosexual 23.8%), THC (LGBTQ+ 30.8%; Heterosexual 24.1%), and CBD e-cigarettes (LGBTQ+ 20.0%; Heterosexual 16.9%). Hispanic/Latino participants generally reported higher rates of past-30-day-use across device types relative to those identifying as Black or White non-Hispanic, particularly disposable nicotine e-cigarettes.Conclusions: Findings highlight sociodemographic disparities in e-cigarette use, though differences varied based on e-cigarette device type and participant birth year category. Tailored preventive efforts may be necessary to mitigate e-cigarette use among populations at highest risk.
