Bold values denote statistically significant findings (p<0.05).

Results adjusted for age, sex, race-ethnicity, country of residence, number of computers, depression, anxiety, alcohol use, harm perceptions of smoked cannabis, & past 30-day nicotine use.

Age, no. of computers, depression, anxiety and harm perceptions of smoked cannabis were modeled as continuous variables.
