This study found:
- Children’s risk of marijuana and alcohol use and attitudes toward marijuana were influenced by their parents’ marijuana use pattern over time.
- Children whose parents used marijuana primarily during adolescence/early adulthood and those whose parents continued to use marijuana from adolescence through adulthood were at highest risk.
When parents use drugs such as marijuana, their children may also be affected. Numerous studies have shown that current parental marijuana use increases the children’s risk of substance use and other psychiatric problems. A recent NIDA-sponsored study demonstrates that the parents’ history of marijuana use throughout their lifetime may also affect their children’s outcomes and that some lifetime use patterns are more harmful than others
