Study of the Cannabis Use of Minors Imprisoned in the PACA Region

To date, there is little data on the consumption of young adults in detention. The main objective of this project is to document the prevalence of problematic cannabis use before incarceration among juveniles detained in the various detention centers in the PACA Secondary objectives are to document: * the prevalence of cannabis use over the course of life, last year and last month; * the prevalence of harm and risky behavior associated with the use of a psychoactive substance * associated addictions and first and foremost tobacco * the determinants (socio-demographic, socio-economic, environmental, etc.) of problem use and cannabis use. This is a multicenter cross-sectional study aimed at establishing an exhaustive picture of the defined population region over a 12-month period. The holder of the parental authority exercise and the individual agreeing to participate in the study must: * sign an informed consent a no objection card * complete a car book and hetero-questionnaires. The time of handover is evaluated at 30 minutes. The CAST questionnaire will be used to answer the main purpose of the study and to identify consumers with problematic cannabis use. CAST scores will be calculated. Abnormal CAST proportions will be presented along with their 95% confidence intervals. The links between the score and the various variables identified as determinants will be tested using uni and multivariate analyzes. The assessment of the health status and needs of this extremely vulnerable population is a prerequisite for defining specific regional objectives and for establishing a coherent and coordinated effective health intervention within the community. prisoner in France.
