The genetic evidence for predisposition seems pretty strong as far as my text books and teachers are concerned. Not the only reason addiction can develop, but certainly genetics seem to create a suceptibility that is difficult to deny. I am going on faith with my textbooks - have not hunted down the actual studies. But twin studies, etc.
Lots of discussion too about the mechanics of addiction in the brain in my classes. And discussion of pharmaceutical aids to recovery.

(but ftr, I welcome the discussion, though I have no interest in what passes for spirited debate around here. I imagine this is boring enough for the people that are still struggling to find a way out that most people will have no interest!)
