Evolving Disparities in Cannabis Use Among Youth by Demographics and Tobacco and Alcohol Use in the U.S.: 2013–2021

Abstract

IntroductionThe current study investigated the prevalence of past 30-day cannabis use among US youth by cigarette use, alcohol use, demographics and state-of-residence cannabis legal status in 2021, and examined whether changes in prevalence were modified by these factors from 2013 to 2021. MethodsData were drawn from the 24 states that collected cannabis use data participating in the Youth Risk Behavior Surveillance System (YRBSS) from 2013-2021. Logistic regression analyses estimated past 30-day cannabis prevalence in 2021 and produced adjusted odds ratios (AOR) by current cigarette, alcohol, state-of-residence cannabis legal status. The same method was used with year as the exposure, adjusting for sex, race and ethnicity, to assess trends in prevalence from 2013 to 2021. ResultsIn 2021, cannabis use was more common among female (16.75% vs. 13.83%, AOR=1.26 (95% CI: 1.16, 1.37)), Non-Hispanic (NH) Black and Hispanic youth relative to NH White youth (17.19%, 16.14% vs. 14.60%; AOR=1.25 (95% CI: 1.12, 1.39); AOR=1.16 (95% CI: 1.04, 1.29)), respectively. Cannabis use was much more common among youth who reported any past 30-day cigarette or alcohol use (44.90% vs. 6.48%, AOR=11.80 (95% CI: 10.57, 13.18)). Declines in cannabis use were observed independent of state-level cannabis law from 2013 to 2021 and cannabis use prevalence did not differ significantly by state-of-residence cannabis legal status among the 24 participating states in 2021. ConclusionsPublic health officials should carefully consider the potential differential impact of expanding commercialization of cannabis and US state government endorsement of cannabis as a “wellness” product on youth, especially with regard to co-use with tobacco and alcohol. National and state-level public health education on cannabis use and youth-oriented prevention of cannabis uptake are long overdue.
