Trends and disparities in self-reported past-month poor mental health among individuals using cannabis in the U.S., 2016-2023.

Using 2016-2023 data from the Behavioral Risk Factor Surveillance System (BRFSS), this study examined trends in self-reported past-month poor mental health (≥ 1 day) among individuals using cannabis and disparities in subgroups. From 2016 to 2023, the prevalence of self-reported past-month poor mental health (≥ 1 day) among those using cannabis increased from 54.54% to 67.88%. Women reported higher rates than men (77.08% vs. 60.14%). Young adults (25-34) showed the largest increase (from 51.42% to 77.67%). Hispanics (69.17%) exhibited the highest prevalence in 2023. Findings underscore the need for mental health screening and targeted counseling as cannabis legalization expands.
