That is a really tough situation- especially raising a child (who is likely at this age to not remember any drama associated with this at this point) . But I hope you give it a shot and also know how to protect yourself in the event things do not go as well after his rehab as everyone hopes. I've never done heroin (I have done about everything else) but I've heard it is a whole different level of addiction. Hang in there, be strong, and most of all protect yourself and your child and know when to say enough is enough if this becomes a cyclical behavior.
