[The community as a place of intervention in the treatment of addictions].

Mobility and shifting of treatment sites to the community is useful and necessary for some individuals with addictions who are unable to access traditional treatment programs. The article presents different treatment models : Assertive community treatment, Housing First and transition programs. The main effects of the programs presented are a reduction in days of hospitalization and the use of emergency services, as well as an improvement in adherence to outpatient care. These are encouraging results given the significant difficulties of a population which often presents the phenomenon of « revolving doors » with very high rates of readmissions and lack of treatment continuity.
