Associations of Parental Marijuana Use With Offspring Marijuana, Tobacco, and Alcohol Use and Opioid Misuse

This cross-sectional study found that parental recent and past marijuana use was associated with an increased risk of marijuana and other substance use by adolescent and young adult offspring living in the same household. As any substance use among young people increases the probability of using other or multiple psychoactive substances and of experiencing substance-related consequences,preventing a cycle of multigenerational substance use should be a national priority.
