[Preventing and regulating psychoactive substance use among occasional and regular adolescents].

The academic success and well-being of young people can be undermined by the use of psychoactive substances (PAS), which is particularly prevalent during adolescence, a period vulnerable to social influences. This article is aimed in particular at school and university preventive medicine nurses. It proposes intervention strategies for adolescents who regularly use such substances. Based on the scientific literature, the aim is to examine how psychological support, coupled with a program of adapted physical activity, could limit the use of APS, a factor in academic failure and health risks.
