The bad things he is doing are the drugs, not your son. He needs to move. You need to protect yourself. But remember the difference between this guy you see and the son you raised. The drugs are what you see today. I don't know enough to advise you, but I do know that your son, that cute 10 yr old boy, would not harm or threaten his mother. I hope he can find his way and survive his connection to the drugs that are controlling him now. IMHO
