Interesting research

I am researching addictions for one of my novels, and found some very interesting information. A protein, deltaFosB, is overproduced in virtually every form of addition, whether drug or behavioural (gambling, shopping, sex, food). Although genetic factors weigh about 50% and environmental factors the other 50%, the physical addiction has a neurological basis. Not a surprise, I suppose, though I would have thought this might have made the news.
