Pregnant / Breastfeeding
Use the Marijuana and Your Baby factsheet for information about the risks of marijuana use during pregnancy and breastfeeding, including health effects, legal issues, safety and available resources.
Marijuana is now legal for adults over 21. But this doesn't mean it is safe for pregnant moms or babies. Using marijuana while pregnant or breastfeeding may harm your baby. THC, the chemical in marijuana that makes a person “high,” can pass from mother to unborn child through the placenta.1 Marijuana that passes to your baby during pregnancy may make it hard for your child to pay attention and learn, especially as your child grows older. This would make it harder for your child to do well in school.1
