Mark, I agree he needs to give up everything. I think it's hard for younger people to understand that you can't pick and choose. When you're an addict, the problem isn't the substance, it's your brain. I'm sure his program covers all the cross-addiction stuff, it's up to him how he applies it. Exposing him to the information he gets in treatment will give him a lot of education to work with. He will figure it out.
