The factors sexual orientation (homosexual p-value=0.02/asexual p-value =0.01), living with college friends (p-value=0.03) and higher income (p-value <0.001), were associated with both more days of consumption and problems. Tobacco use in the last 30 days was associated with more days of cannabis consumption (p-value=0.02) and higher levels of stress linked to consumption-related problems (p-value=0.05).
