Cannabis and Breastfeeding

The short answer is no: major medical organizations, including the American Academy of Pediatrics and the American College of Obstetricians and Gynecologists, advise against using cannabis or CBD while breastfeeding. THC passes into breast milk, and there is no established safe amount. If you use cannabis and you are nursing, talk with your obstetrician or your baby's pediatrician before your next feeding.

Is It Safe to Use Cannabis While Breastfeeding?

Health agencies recommend avoiding cannabis during lactation because no known safe level exists. A single exposure is not a reason to panic or to stop nursing abruptly, but it is a reason to get personalized medical guidance quickly.

Key Points to Know

• THC is fat-soluble and concentrates in breast milk; it can be detected in an infant's urine and blood after exposure.
• Reported infant effects include drowsiness, poor feeding, slow weight gain, and subtle developmental differences in some studies.
• Secondhand smoke from any smoked product is harmful to infants regardless of how they are fed.
• Heavy or daily use carries more risk than isolated use, and edibles or concentrates can deliver far higher doses than expected.
• Alcohol, nicotine, and prescription medicines each have their own lactation guidance, so ask about them separately.
• Pumping and dumping does not speed THC clearance, because it is stored in body fat rather than in the milk itself.
• State legality does not change the lactation recommendation.

What About CBD Products?

CBD is not automatically the safer option. CBD oils, gummies, and topicals sold online are largely unregulated, and independent testing has repeatedly found products containing THC, pesticides, or amounts of CBD that differ from the label. A topical applied away from the chest area has minimal absorption, but ingested CBD can build up with daily use, and there is very little research on how much of it reaches breast milk. If you do buy, look for a current third-party certificate of analysis, a clear cannabinoid profile, and a batch number printed on the label.

Ordering online also means relying on the seller's policies, so check that lab results are published before purchase and confirm the return window and whether opened products can be sent back. A retailer that is vague about testing or refunds is not one to rely on while you are weighing infant exposure.

Where Can Parents Get Support?

A lactation consultant, your OB-GYN, or your baby's pediatrician can review your specific situation, including any medicines you take. InfantRisk centers and poison control lines also answer questions about substance exposure during breastfeeding.
