Influence de la consommation de cannabis sur les idées suicidaires chez 491 adolescents scolarisés

This result suggests an association between suicidal ideation, depressive symptoms and cannabis use in adolescents. Cannabis use appeared to be an independent predictor of suicidal ideation after controlling for depressive symptoms. However, the increment of variance accounted for by cannabis use was small. This suggests that cannabis use contributes to suicidal ideation independently from depressive symptoms, but weakly. A limitation to the study was the absence of control for other potential confounding variables. The association between cannabis use and suicidal ideation may be linked to common risk factors such as borderline personality disorder traits, sociodemographic and family factors. In this study, cannabis use does not appear as an important risk factor for suicidal ideation in adolescents.
