In France, the "Consultations Jeunes Consommateurs" (CJC) are the services specialized in the reception of young people for addiction problems. There are more than 500 CJCs throughout France. Depending on the situation, the CJC develops an early intervention strategy aimed either at reducing the risk of developing an addiction or at accelerating entry into appropriate care. The CJCs also meet with family members or professionals who may also independently request help or advice.
Set up by the State since 2004, the action of the CJCs has never been formally evaluated. Only descriptive studies, carried out by the French Observatory of Drugs and Drug Addiction (OFDT), have made it possible to better understand the profile of people who consult CJCs. However, no longitudinal study has yet been carried out to understand the factors associated with the overall evolution of users consulting CJCs, nor with the level of satisfaction of users and those around them. Such objectives are complex, due to the diversity of situations encountered in CJCs and the heterogeneity of the CJCs themselves.
This multicenter study will be open to 19 CJC (Consultations jeunes Consommateurs), based on a pre-selection by the partners of structures that are particularly willing to participate in the study (Fédération Addictions, Addictions-France).
However, other CJCs may be included depending on the progress of recruitment.
This recruitment of additional CJCs will be stratified to target a sample of CJCs representative of the CJCs on the metropolitan territory on the following characteristics:
