Abstract

Highlights: This study investigated changes in cannabis use disorders (CUDs) by smoking status. The prevalence of CUD increased from 2002 to 2016 among non-daily smokers. The prevalence of CUD did not change from 2002 to 2016 for daily smokers. In 2016, CUD was 2–4 times more common among smokers than non-smokers. In 2016, youth who smoked were 10–14 times more likely to meet criteria for CUD. Abstract: Background: Cannabis use is on the rise in the United States (US) and is disproportionately common among cigarette smokers. Cannabis use disorder (CUD) occurs among a small subset of cannabis users and may impact cigarette use. The objective of this study was to estimate trends in the prevalence of CUD among daily, non-daily, former, and never cigarette smokers from 2002 to 2016. Methods: Data were drawn from cross-sectional, nationally representative samples of individuals ages 12 and older in the US that were collected annually. The prevalence of past 12-month CUD was estimated each year from 2002 to 2016 among daily, non-daily, former, and never cigarette smokers (total analytic N = 837, 326). Results: Overall, the prevalence of CUD decreased from 2002 to 2016. Yet, trends differed by cigarette smoking status. Adjusting for demographics, the prevalence of CUD increased significantly among non-daily smokers (aOR = 1.02; 95% CI = 1.01–1.03) from 2002 to 2016 and did not change among daily, former, or never smokers. CUD was significantly more common among non-daily (4.32%) and daily cigarette smokers (2.92%) compared with former (0.99%) and never smokers (1.11%) in 2016. Approximately one in five (18.11%–22.87%) youth ages 12–17 who smoke cigarettes met criteria for CUD in 2016, compared with approximately 2% of non-smoking youth. Conclusions: Despite downward trends in CUD observed at the general population level, the prevalence of CUD significantly increased among non-daily cigarette smokers from 2002 to 2016. In the US, CUD remains significantly higher among cigarette smokers relative to non-cigarette smokers.
