Im 17 years old and i recently found out that i am a heroin baby. i was wondering what long term symptoms there are?

Do some research: Sadly, there are long term risks for heroin babies but it seems that the problems are worst at the very beginning of life. If you have had a reasonably healthy infancy and childhood you probably escaped the threat. That's great! but you can find and read information or talk with a knowledgeable doctor.
