Assessment of nicotine and cannabis co-use among adolescents and the association with nicotine and cannabis dependence symptoms.

ABSTRACT:

Significance

Adolescent nicotine and cannabis co-use is common, but prior studies use imprecise measurement of co-use which may not capture the most problematic behaviors such as same-day use.

Methods

This cross-sectional study examined patterns of nicotine and cannabis co-use among Southern California high school students in Fall 2022 (N = 3823). Participants were classified into five mutually exclusive past-month nicotine and cannabis use groups: 1) same-day co-use: use of both substances on the same day at least once; 2) past-month co-use: use of both without same-day use; 3) exclusive nicotine use; 4) exclusive cannabis use; 5) no use of either. Adjusted logistic regression models evaluated the association of co-use with any nicotine and/or cannabis dependence symptoms.<
