Figure 1. Estimated relative hazards of acute care utilization according to patient-reported frequency of past-year cannabis and other drug use, overall and by subgroup

Overall and stratified hazard ratios for frequency of past-year cannabis use (panel 1) and other drug use (panel 2) estimated using Cox proportional hazards models with robust standard errors, adjusted for demographic characteristics and stratified by clinic. Estimates are relative to no past-year use and are presented on the log-scale with 95% confidence intervals.
