Abstract: Self-reported substance use and delinquent behavior were assessed yearly, 3 times beginning in the sixth or seventh grade, for a multiethnic sample of middle school students (n= 5,045). Both substance use and delinquent behavior became more prevalent across early adolescence, but only a small fraction of adolescents were using illicit substances at the end of the study.
