Marijuana

Using marijuana while breastfeeding can allow harmful chemicals to pass from the mother to the infant through breast milk or secondhand smoke exposure. To limit potential risk to the infant, breastfeeding mothers who use marijuana should be encouraged to abstain from or significantly reduce marijuana use.

Is it safe for mothers who use marijuana to breastfeed?

Data are insufficient to say yes or no. Chemicals from marijuana in any form (including edibles, oils, or other concentrates) can be passed from a mother to her infant through breast milk. These chemicals have the potential to affect a variety of neurodevelopmental processes in the infant. Tetrahydrocannabinol (THC), the main active component of marijuana, is stored in body fat and slowly released over time, meaning an infant could be exposed to an unknown amount and for an extended period of time. However, data on the effects of marijuana exposure to the infant through breastfeeding are limited and conflicting. To limit potential risk to the infant, breastfeeding mothers who use marijuana should be encouraged to abstain from or significantly reduce marijuana use.

Medicinal Marijuana

When advising mothers on the medicinal use of marijuana while breastfeeding, consideration should be given to the potential risks of marijuana exposure and benefits of breastfeeding to the infant and mother.

Marijuana use may also impair a mother or other caregiver’s judgement and ability to care for an infant.
