Cannabis is a plant of the Cannabaceae family and contains more than eighty biologically active chemical compounds. The most commonly known compounds are THC and CBD. One type of cannabis plant is marijuana, which contains varying levels of THC, the compound that produces the “high” that is often associated with marijuana. Another type of cannabis plant is hemp. Hemp plants contain extremely low amounts of THC. CBD, which does not produce a “high,” can be derived from either marijuana or hemp.
Moreover, CBD has known risks for people in general. Based on clinical studies in humans, risks can include the following:

Additionally, marijuana smoke contains many of the same harmful components as tobacco smoke. Neither marijuana nor tobacco products should be smoked around a baby or children.
There are many potential negative health effects from using marijuana and other products containing THC during pregnancy and while breastfeeding. In fact, the U.S. Surgeon General recently advised consumers that marijuana use during pregnancy may affect fetal brain development, because THC can enter the fetal brain from the mother’s bloodstream. The Surgeon General also advised that marijuana may increase the risk of a newborn with low birth weight. Research also suggests increased risk for premature birth and potentially stillbirth 1 .
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.
Geary (who notes that as a pediatrician with a license to provide medical marijuana —CBD and THC products—she’s not an anti-marijuana doctor), says using CBD when breastfeeding just isn’t a safe gamble. “During the time of the developing fetus, through until age three years of life, the infant’s brain reaches 80% of its full adult volume. Any unnecessary exposure, especially in those vulnerable first three years, is worth considering very seriously.”
Try to use nursing sessions as a time to pause and reset, letting the oxytocin that’s released during breastfeeding help you enter a state of calm. Play soothing music or a guided meditation, practice deep breathing, and remember that this stage of life is temporary.

Risks of Using CBD When Breastfeeding
Until we have more evidence, Geary says women who are expecting or breastfeeding should definitely err on the side of caution and avoid cannabis in all forms.
Thomas warns to be skeptical of CBD products that are inexpensive. Seek out reputable brands that use conscious farming practices. “None of this stuff is cheap,” she says. “This is an expensive process.”
She says it’s crucial, however, that you bring the product you intend on using to your health care provider and discuss its use before trying it out. She also says it’s important to realize if you choose to use CBD topically when breastfeeding, it’s still considered experimental. “Never feel forced to use something just because you bought it,” she adds.
Geary adds, “A very real problem is that the products are unregulated and may be contaminated with harmful chemicals—such as pesticides, bacteria, fungus, and heavy metals—which can harm the fetus or baby.”
