Notes. Analyses used logistic regression. N= 269 for hazardous drinking and N = 121 for cannabis use samples. Hazardous drinking = any days of ≥4 drinks (for women) or ≥5 drinks (for men) in the prior 30 days, measured at 6 months. MI = Motivational interviewing. OR= odds ratio. 95% CI = 95% confidence interval. Specialty care substance use treatment (yes/no), antidepressant use (yes/no) and number of psychiatry visits since study enrollment were measured at 6-month follow up.
