Title: Cannabis use and depression and suicidal thoughts and behaviors during adolescence: comorbidity and direction of association in a general population sample from Quebec
Question: What is the developmental direction of association between cannabis use and depression and suicidal ideation, e.g. whether cannabis use precede depression and suicidal ideation (secondary psychiatric disorder hypothesis), or vice-versa (self-medication hypothesis)
Strategy: Use data from the Quebec Longitudinal Study of Child Development (QLSCD; n=2120). Repeated information on cannabis use, suicidal ideation and depression modeled using structural equation modelling.
Impact: Better inform prevention and intervention strategies given the potential for misguided perceptions of safety with cannabis use among adolescents
