Illegal drugs in pregnancy - Your pregnancy and baby guide

Using illegal or street drugs during pregnancy, including cannabis, ecstasy, cocaine and heroin, can have a potentially serious effect on your unborn baby.

If you regularly use drugs, it's important to tackle this now you're pregnant. 

It's best not to stop abruptly without first seeking medical advice as there may be withdrawal problems or other side effects.

What if I took drugs before I knew I was pregnant?

If you took a drug without realising you were pregnant on a one-off occasion, try not to worry – it's unlikely to have affected your baby.

But if illegal drugs are part of your life, getting help can really improve the outlook for you and your baby.
