Abstract:
EPIDEMIOLOGICAL OVERVIEW OF PSYCHOACTIVE SUBSTANCE USE IN France. Consumption of psychoactive substances (tobacco, alcohol, illicit drugs) remains high in France, although downward trends are being observed, particularly among young people. Tobacco remains the leading cause of avoidable mortality, with 75,000 deaths in 2015, followed by alcohol (41,000 deaths). The overall social cost is considerable, reaching 266 billion euros in 2019. Social inequalities are high for tobacco, less so for alcohol. Vaping is on the rise, and is a particular concern among teenagers, among whom it is now more common than smoking. Illicit drug consumption levels are much lower, including for cannabis, the most widely used illicit substance, especially among young men. Despite progress, prevention and support for consumers remain essential to limit the health and social impacts.
