Table 1 National guidelines for breastfeeding in the setting of marijuana

Centers for Disease Control and Prevention (Marijuana 2021)

Using marijuana while breastfeeding can allow harmful chemicals to pass from the mother to the infant through breastmilk 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.

American College of Obstetricians and Gynecologists (Marijuana Use During Pregnancy and Lactaqtion 2017)

There are insufficient data to evaluate the effects of marijuana use on infants during lactation and breastfeeding, and in the absence of such data, marijuana use is discouraged.

American Academy of Pediatrics (Policy Statement: breastfeeding and the use of human milk 2012; Ryan et al. 2018)

Present data are insufficient to assess the effects of exposure of infants to maternal marijuana use during breastfeeding. As a result, maternal marijuana use while breastfeeding is discouraged.

Academy of Breastfeeding Medicine (Reece-Stremtan and Marinelli 2015)

Breastfeeding mothers should be counseled to reduce or eliminate their use of marijuana to avoid exposing their infants to this substance and advised of the possible long-term neurobehavioral effects from continued use.
