Posted in:Expecting a BabyHome Visiting


Just once or on occasion is a big NO when it comes to marijuana use. No amount of marijuana is safe to use during pregnancy or after breastfeeding. You can still pass the harmful substance to your baby through breast milk.  Although the use of medical marijuana is legal in Delaware, marijuana use in any form during pregnancy or breastfeeding poses potential risks for your baby.

Here are some things we want you to know so that you can protect and care for your baby:

According to the Center for Disease Control and Prevention, THC (a chemical found in marijuana) “is stored in fat and is slowly released over time, meaning an infant could be exposed for a longer period of time.”  This means that even if it was JUST ONE TIME your baby could still be exposed to the substance during multiple feedings.

If you expose your baby to the chemicals in marijuana through breastmilk, there is an increased chance of developmental problems later in life. This means that as your baby grows up, they might have trouble meeting major milestones. For example, they could struggle to raise their head while lying on their stomach or they could have trouble moving an object from one hand to another.
