Figure. Event Study Analysis.

Unweighted estimates from separate logistic regressions based on biennial data from the Youth Risk Behavior Surveys (1993-2017) are reported. Specifically, estimated odds ratios (ORs) and 95% CIs of marijuana use and frequent marijuana use are reported. Odds ratios were adjusted for individual-level characteristics (age, sex, grade, and race/ethnicity), whether marijuana use and possession were decriminalized in the respondent’s state, the presence of a state-level 0.08 blood alcohol concentration law, the state beer tax, state income per capita, state unemployment rate, and indicators for 50 states and 12 years. The omitted category was 1 year prior to a medical marijuana law (MML) going into effect. N = 1 414 826.
