Can I Use Weed While Pregnant? or Breastfeeding?

Published scientific literature suggests negative results of cannabis usage in pregnant females, including:

  • fetal development restriction,
  • low birth weight,
  • preterm birth,
  • small-for-gestational age,
  • neonatal intensive care unit (NICU) admission, and
  • stillbirth

The American College of Obstetricians and Gynecologists (ACOG) suggests that women who are pregnant or considering becoming pregnant should stop cannabis use.

  • Breathing marijuana smoke can also be bad for you and your baby. Marijuana smoke has many of the same chemicals as tobacco smoke and may increase the chances for developmental problems in your baby


The short answer to the question Can I Use Weed While Pregnant or Breastfeeding? is No, you shouldn’t. The use of cannabis, whether it’s taken for medical or recreational purposes, should be discussed with your healthcare provider to determine the purposes, especially if being used for therapeutic conditions, to find alternative solutions during your pregnancy and while breastfeeding.
