Notes: IRR = Incidence rate ratio. Alcohol and marijuana frequency are measured in the past 30 days (5a). SAM frequency is measured in the past 3 months (5b). Other is the reference group for White and Asian. Female is the reference group for male; those who selected a non-binary gender identity (n = 29) were eliminated from these analyses. School B (decriminalized) is the reference group for School A (illegal) and School C (legal for 21+). Difficult access to marijuana is the reference group for Fairly Easy and Very Easy access.
