I would go see him every weekend that I possibly could. I think that your support when he is applying himself speaks volumes and is very precious to him. If he gets well, what could be more important than that? I wouldn't take his interest in seeing his peers on his home visits to mean anything more than he is a teenager and peers are very important to them. But I would limit the time he spends with them as has been suggested by others. He has to learn to make his own choices. If you restrict who he can see it won't mean a thing. It will only mean something to him when "he" makes the choice to eliminate them. I think it is great he didn't participate in the pot smoking. Maybe he hasn't bought into the whole sobriety concept yet and is only abstaining because of the consequences. But I think that is okay, too. My difficult child was sober for a 9-10 month period (except for the brief periods he was home, relapsed and was re-admitted) because he had no choice. And now he is home and sober on drug court and probation. The longer we can keep them sober, the clearer their mind becomes, the more therapy we can do, the more changing of their thinking occurs. Like I always say, it's a process. One baby step at a time.
