	OR (95% CI)	AOR (95% CI)
Chronic users vs. No or low users	10.93 (6.51, 18.35) ^***	11.07 (6.07, 20.21) ^***
Increasing users vs. No or low users	6.94 (3.92, 12.28) ^***	7.04 (3.72, 13.33) ^***
Moderate users vs. No or low users	3.13 (1.72, 5.69) ^***	3.32 (1.75, 6.29) ^***
Chronic users vs. Increasing users	1.60 (0.86, 2.99)	1.79 (0.89, 3.62)
Chronic users vs. Moderate users	3.02 (1.62, 5.61) ^***	2.86 (1.46, 5.60) ^**
Increasing users vs. Moderate users	2.03 (1.03, 4.02) ^*	2.03 (0.95, 4.31)

Note: 1. * p<.05, ** p<.01, *** p<.001;

2. OR = Odds ratios without controls;

3. AOR = Adjusted odds ratios by including depressive symptoms, low self-control, delinquency, tobacco use, alcohol use, other illicit drug use, gender, ethnicity, and age at T1as controls.
