Question: If someone smokes marijuana while breastfeeding, what can happen to the baby? are they put at risk of anything dangerous? - J.C.
Answer: Dear J.C.,
Marijuana, aside from being illegal in this country, is contraindicated -- considered inadvisable --during breastfeeding. Leading medical authority Dr. Thomas Hale, PhD, author of Medications and Mothers' Milk places marijuana in the highest risk category. Marijuana is rapidly distributed to brain and fat tissue and is stored in the body for long periods of time, making it unsafe for baby.
Mothers who use marijuana while nursing can have eight times as much
marijuana accumulation in breastmilk as compared to their own blood.
Additionally, infants exposed to marijuana via breastmilk can test
positive in urine screens for up to 2-3 weeks.
