Correlation between percentage of hospitalizations with diagnosis of psychosis associated with cannabis use (adjusted for covariates) in each census division and Census Division Cannabis Legality Score (r=0.67, p<0.05). The Census Division Legality Score was calculated as sum of state legality scores weighted by proportion of state population in census division. State legality scores were defined as: 1 = illegal or cannabidiol/low potency cannabis, 2 = standard medical marijuana and 3 = recreational and medical marijuana. Census Division Cannabis Legality Scores ranged from 1 – 3.
