Épidémiologie des usages de substances addictives : résultats d’études réalisées en France et perspectives internationales

Addiction to drugs is an important public health concern. Describing the frequency of dependence, abuse and use of substances in a country allows a monitoring and helps in the design of an appropriate healthcare system. We will present studies describing the prevalence of use of tobacco, alcohol, and illicit drugs in France, with a comparison to European or International studies. They show a decrease in the use of tobacco and cannabis, while there is an increase in alcohol use in young adults. We also observe that the difference in substances use between females and males is tightening, especially in young people. We have less studies of analytic epidemiology trying to describe risk or protective factors associated with substances’ use in France. Further studies on addicted people's pathway (from use to abuse and to dependence, as well as from dependence to recovery, with or without medical support) are warranted.
