What you need to know about cannabis and pregnancy
- The chemicals found in all forms of cannabis, including edibles such as cookies and gummies, may be bad for babies.
- Chemicals from cannabis (particularly THC) can be passed to a baby through a mother’s breast milk4. However, data on the effects of cannabis exposure to the infant through breastfeeding are limited and conflicting. To limit potential risk to the infant, breastfeeding mothers should reduce or avoid marijuana use.
