Study staff administered surveys in classrooms. Students who were no longer attending school were interviewed over the telephone. Items were included to assess whether or not students answered the survey questions honestly. Students were categorized as dishonest if they reported that they were not honest at all when filling out the survey, had used a fake drug, or had used illicit drugs on more than 120 occasions in the past 30 days. Few students in the initial sample (17 at wave 1, 35 at wave 2, 6 in both waves) met the criteria for dishonesty. The analysis included only “honest” students.
