Consuming cannabis (marijuana, weed, pot) can affect the health of your baby and is not recommended for women who are pregnant or breastfeeding, or who plan to become pregnant soon.
Research shows that if you use cannabis while you are pregnant or breastfeeding, your baby may be born with a lower birth weight, which means the baby is more likely to have health problems, especially in the first year of life.
No matter how you consume cannabis (smoking, vaping, eating, or drinking), the active ingredient in cannabis, THC (tetrahydrocannabinol), will reach your baby through your bloodstream and into the placenta, through your breast milk, and through secondhand smoke that enters the baby's lungs.
Because the health of your baby is important to you, check out the resources below and learn more about how cannabis use during pregnancy or while breastfeeding affects your baby.
