Marijuana During Pregnancy & Breastfeeding

For Families

Consuming marijuana (weed, pot, cannabis) in any form (smoking, vaping, edibles, drinks, etc.) can affect the health of your baby and is not recommended for those who are pregnant or breastfeeding, or who plan to become pregnant soon.

  • Research has shown that marijuana use during pregnancy can lead to low birth weight babies. Low birth weight means babies who are born too small and have increased risk of health problems, especially in the first year of the child's life.

  • Research has also shown that marijuana use during pregnancy or while breastfeeding can harm the growth and development of your baby’s brain.

  • Marijuana can reach your baby in three ways:

    • through your bloodstream during pregnancy

    • through your breast milk

    • through secondhand smoke that enters the baby's lungs


  • No amount of marijuana is safe during pregnancy or breastfeeding, even if it is legal in California. Talk to your healthcare provider about any questions you have about marijuana


  • Breastfeeding is important for the health of both mom and baby. For more information, or to find breastfeeding support, click here.
