Models controlled for age, race/ethnicity, gender, mother’s education, CHOICE intervention group at wave 1, and frequency of past-month marijuana use. B = unstandardized effect estimate from ordinary least squares regression model; IRR = interval rate ratio from Poisson regression model; AOR = adjusted odds ratio from logistic regression model.
