Recreational Substances

Drugs of abuse are generally contraindicated in nursing mothers. One possible exception may be occasional marijuana use1,2.

Because we know the active components of marijuana are excreted in breastmilk and concentrate in the developing brain of infants, marijuana use in lactation should definitely be discouraged. Exposure to the smoke itself should also be avoided. But the risk of completely weaning because of occasional marijuana use may be greater than the risk of not breastfeeding. Research on this topic is a work in progress. Latest information is available at Lactmed, the Infant Risk Center, and Mothertobaby.org, as listed above.
