[Cannabis consumption in young people living in Brussels: observational conclusions drawn from a preliminary study].

: A qualitative study was carried out to explore the adolescents' representations of cannabis and related behaviors. Twenty-two young people aged 13 to 18 years and living in Brussels were interviewed using a half structured interview guideline. The analyse showed that there are three types of behaviors related to cannabis use: the non-users, the experimenters and the users. Parents, the school and peers seem to be specific determinants of cannabis use as well as the main information channels about this product. These preliminary results already lead ways to prevention: training of parents and teachers and school improvement.
