What you put in your bodyCan pass to your baby

While there are still a lot of unknowns about marijuana’s effects, we do know that there is no safe amount of marijuana to use while pregnant or breastfeeding. Read on to learn more about how to make the healthiest, most responsible decisions for you and your baby.

How marijuanaImpacts your body

There is no safe amount.

Simply put, there is no known safe amount of marijuana while pregnant. No matter if it’s smoked, vaped or eaten, THC gets passed on to your baby and may have a long-term impact on your child's ability to learn. Be sure to talk to your doctor early in your pregnancy about marijuana use.

Pumping and dumping isn’t a solution.

If you use marijuana while breastfeeding, your child is exposed to it. THC is stored in fat cells, so pumping and dumping doesn’t work. THC can remain in your breast milk even after you’ve stopped using it. Talk to your doctor if you have any questions.

Medical use while pregnant or breastfeeding.

Using medical marijuana as a new mother is a choice best made between you and your doctor. It isn’t a good idea to use any medicines while pregnant or breastfeeding unless they are recommended by your doctor, so talk with a professional about whether or not the benefits outweigh the risks. 

Secondhand marijuana smoke isn’t safe for you or your baby.

Secondhand smoke from marijuana has many of the same cancer-causing chemicals as tobacco smoke. Make the safest, healthiest and most responsible choice and keep your home smoke-free.

Sometimes it can be difficult to tell what information about marijuana and pregnancy is most trustworthy. You can’t believe everything you read or hear, so use this page as a resource first. The Colorado Department of Public Health and Environment constantly reviews all available marijuana research, which you can read a summary of here. If you still have questions, it’s always best to talk with your doctor before making a decision.

Is marijuana safe to use while pregnant or breastfeeding?

No, there is no known safe amount of marijuana to use while pregnant or breastfeeding. No matter how it’s used, THC always gets passed to your baby.

It’s legal, so doesn’t that mean it’s safe?

The fact that it’s legal does not make it safe. Using marijuana during pregnancy or while breastfeeding may harm your baby, just like alcohol or tobacco.

It’s natural, so doesn’t that mean it’s safe?

Marijuana contains THC, which may harm your baby. Not all natural substances or plants are safe -- think of lead, tobacco, and poisonous berries as examples.

What about using it for medical reasons?

It’s unsafe to use any medicines while pregnant or breastfeeding that are not recommended by a doctor. In special cases, a doctor can decide whether the benefits of marijuana are greater than the risks, and can recommend marijuana while pregnant or breastfeeding. Talk to your doctor about safer choices that do not risk harming your baby.

Don’t cannabinoids occur naturally in your body?

Some cannabinoids, which are called endocannabinoids, occur naturally in the body and can help your nerve cells communicate better. However, THC from marijuana is much stronger and can upset the natural endocannabinoid system in both your body and your baby’s body. 

Can I use it to treat my nausea?

No matter how it’s used or what it’s being used to treat, THC always gets passed to your baby. Talk to your health care provider about safer options that do not risk harming your baby.  

Is it still harmful if I vape or eat it instead of smoke it?

Marijuana in any form contains THC, which is passed to your baby and can cause harm.
