Hello rose1985: This is all really something that requires the attention of mental health professionals. I don't know how old your son is. Assuming he is an adult, he has to make the choice to seek treatment. If he will not, then it is left to you to establish boundaries... to decide how much of this you can tolerate... drugs, weed, caffeine-laced energy drinks... these are not the choices of a person who is trying to get well... My best wishes to you...
