[The role of specialized treatment in school's substance use and misuse].

As it is the case in other European countries, substance use and misuse is increasing among teenagers in Switzerland. This fact is worrying, and requires the application of specific primary and secondary prevention programs to this population, particularly in schools. The pilot-study DEPART makes available to network professionnals, as well as to adolescents (12 to 20 years old) and their family, an interdisciplinary team that provides specific support for substance use and misuse among teenagers. Thus, this pilot-study, which is currently being carried out in and around the city of Lausanne, aims at the early identification and treatment of adolescents in schools (secondary prevention).
