Cannabis is now legal in many states in the U.S. But being legal doesn't mean it’s safe for everyone. Cannabis use in pregnancy can harm your baby.
This includes:
-
Smoking.

Vaping.

The chemicals in cannabis can be passed to your baby. They pass through the placenta. They also pass through breastmilk.
Be open with your health care provider about your use of cannabis and other drugs. They want to help you and your baby be healthy. During prenatal visits, your provider will ask you questions about cannabis, alcohol, and medicines you take. If you need help to stop using a substance, they can help you start treatment. They can refer you to a specialist. Your provider can help you prepare for the safest birth and care of your baby.
