Abstract: Aim: Adult and adolescent Inuit from Nunavik show some of the highest prevalence of cannabis use in the world, particularly for youth. Knowledge of the factors that explain this phenomenon in this region is lacking. According to Bronfenbrenner (1979), family is the closest unit for adolescents and is susceptible to particularly influence their behaviors. The aim of this longitudinal study is to examine longitudinally the association between maternal use of cannabis and the subsequent use of this substance by their adolescents in an Inuit population. Hypothesis: A higher cannabis frequency use among mothers will be associated 1- with more rapid initiation of cannabis, 2- and more frequent use among their adolescent. Method: This study was based on longitudinal data from the Nunavik Child Development Study (NCDS). This study used data from two follow-ups, between 2005 and 2010 (T1: time 1, youth: 8-15 years old), and between 2012 and 2016 (T2: time 2, youth: 16-22 years old). Structured interviews were used to assess maternal cannabis use and other concomitant variables at T1, and for adolescents at T2. Our sample included 184 mother-adolescent dyads. Hypotheses were tested using a Cox regression analysis and ordinal regressions. Results: No significant associations were found between mothers’ frequency of cannabis use and adolescents initiation age as well as regarding the adolescents’ frequency of cannabis use. Nevertheless, a higher socioeconomic status and going to school were associated with a lower risk of frequent cannabis use by the adolescents. Conclusion: The expected association between maternal cannabis consumption and cannabis use of young Inuit was not found. The search for predictors of substance use remains relevant to minimize the accumulation of vulnerabilities experienced by Aboriginal populations.
