⁺Results control for gender and race/ethnicity; Estimator = Maximum Likelihood

^a: Student profiles were a function of baseline substance use (No Use, Use) and recall of TCYL program receipt at Grade 7 (Recall, No Recall)

^b: Odds Ratios = e ^{logistic coefficient}

^*p< .05;

^**p< .01

Note: A positive relationship corresponds to greater substance use.
