I see no problem talking with him. He may not know what he should do. You talking to him might point him in the right direction but don't be his caretaker. Make suggestions and then back out of it and let him do the work. You suggested to him to talk to his sponsor about the step work. Let it go at that. The heroin subject, I think will take care of itself. Identifying with one another is what works. Either he'll identify or he won't.
