Sokol NA, et al. - Using a nationally representative longitudinal cohort of mothers and their children, researchers ascertained whether mothers’ cannabis use is associated with earlier cannabis initiation by their children. They obtained mother and child data from the National Longitudinal Survey of Youth 1979 (1980–1998 waves) and Child and Young Adults (1988–2014 waves) cohorts, respectively. Median age of cannabis initiation for children of maternal ever users was 16 years of age vs 18 years of age among children of maternal never users. Researchers found some evidence to suggest that race might have modified the effect of maternal cannabis use on child cannabis initiation, with the strongest and most consistent effects observed among non-Hispanic non-black children. Additional findings revealed that maternal cannabis use may be a risk factor for early initiation among their offspring. The researchers recommended the inclusion of strategies to delay initiation as a part of preventative interventions for children of cannabis users.
