Group of Pregnant PeopleHealth Considerations for People who are Pregnant or Breastfeeding

People who are pregnant, trying to get pregnant, or breastfeeding should not use any cannabis products. Because all the possible harms are not fully known, the American College of Obstetricians and Gynecologists (ACOG) recommends that anyone who is pregnant or breastfeeding avoid using cannabis products.

Cannabis products contain THC (the ingredient that gives people the "high") and other chemicals. No matter if cannabis is smoked, vaped, or eaten, these chemicals travel through the bloodstream and into the placenta, the organ that feeds oxygen and nutrients to the baby.

Some studies suggest that using cannabis during pregnancy could be linked to lower birth weight of the baby and may impact the baby's motor development and neurodevelopment.

Baby BreastfeedingBaby BreastfeedingTHC can also be passed to the baby through breastmilk. Studies show that breastmilk can contain THC for up to six days after use. It is best to stop cannabis use while breastfeeding instead of stopping breastfeeding, so that both the baby and the person who is breastfeeding can receive the health benefits of breastfeeding.

If you are pregnant or breastfeeding and using cannabis, read the Cannabis and People Who are Pregnant or Breastfeeding​ (PDF) resource for information on what you can do to keep your baby safe.
