Unweighted N for initiation sample = 15 280; unweighted N for progression sample = 26 998. Attrition weights were used to generate estimates, which account for the complex survey design of the Monitoring the Future study, oversampling of drug users, and attrition; SE are in parentheses; pairwise deletion was used for missing data. “~” indicates that particular variable was not included in analyses.
