Note: The dash (–) indicates reference group. Sample sizes ranged from 865 (marijuana use in past year, five-category measure) to 917 (cigarette use in past 30 days, three-category measure) due to missing responses. The models for other illicit drug use for the three-category and five-category measures did not converge
