It is sometimes possible to prevent substance use by addressing other social and emotional concerns facing children and young people. For example, a program called Fast Track — aimed at preventing conduct problems — also reduced problematic substance use in general and alcohol misuse in particular. Similarly, the Montreal Prevention Program aimed to reduce behaviour problems with disadvantaged seven-year-old boys also reduced the number of drugs the boys tried when they were between 14 and 17 years old. As well, a cognitive-behavioural therapy program designed to prevent adolescent depression also significantly reduced substance use two years after the program ended.
