Cannabis use and suicidal ideations in high-school students

Background: The association of cannabis use and suicidal ideations in adolescents has been inconsistent This discrepancy may reflect differences in controlled confounders. In particular, no study has controlled for personality disorder traits linked to both cannabis use and suicidality such as borderline and psychopathic personality traits. Method: Participants were 972 high-school students who completed questionnaires assessing cannabis use, suicidal ideations, depressive symptoms, social anxiety symptoms, and borderline and psychopathic personality traits. Results: Cannabis use was not a significant independent predictor of suicidal ideations after adjustment for confounding personality traits in the total sample and in the subsample of cannabis users.
