Key Points

Question  Is parental marijuana use associated with marijuana, tobacco, and alcohol use and opioid misuse by adolescent and young adult offspring living in the same household?

Findings  In this cross-sectional study including 24 900 father-offspring or mother-offspring dyads, parental marijuana use was associated with increased risk of marijuana and tobacco use and opioid misuse by both adolescent and young adult offspring and of alcohol use by adolescent offspring.

Meaning  Screening household members for substance use and counseling parents on risks posed by current and past marijuana use may be helpful in the effort to prevent a cycle of multigenerational substance use.
