Im pretty much in the same boat as you, son 20 using not sure what , hes in a pretty bad state atm. Since he was a little boy I talked to him of the dangers of drug use, it didnt stop him from trying and then continuing ,at times I think i didnt do enough of a good job, wasnt smart enough, wasnt there enough , Im also coming to hard terms with the fact that I am helpless in getting him to recover. Im sorry what your going through I can offer my prayers to you and your family.
