We are now seeing CBD-containing products everywhere. CBD can be found in many different products, like drugs, foods, products marketed as dietary supplements, and cosmetics. These products often make questionable health promises about CBD.
What do we know about the effects of marijuana use during pregnancy and while breastfeeding?
The clinical studies that supported the approval of the one available CBD drug product identified risks related to the use of CBD, including liver toxicity (damage), extreme sleepiness, and harmful interactions with other drugs.
What about hemp seeds?
We especially want to learn more about the effects of CBD during pregnancy and while breastfeeding, including, for example, whether and to what extent the presence of CBD in human milk harms the breastfed baby or the mother’s milk production.
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 should be advised not to use marijuana or products containing cannabidiol (CBD) in any form while breastfeeding.
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. In addition, some products, including cannabidiol (CBD) products, may contain other contaminants (e.g., pesticides, heavy metals, bacteria, and fungus) that could be dangerous to a mother and her infant.
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.
