If you're an addict or alcoholic like me and have been wondering for years WHY? This video did more for me to explain the processes of the brain that are responsible for creating addiction to anything, Heroin or sugar cookies. It tells how the American Medical Association finally came up with a model for calling drug addiction and alcoholism a disease. I could never understand how it could be a disease, now I do. It's not that hard to understand what the video explains by a doctor who is an recovering addict. He keeps it pretty simple but very informative. Buy it, watch it, you'll get more from this than you expect.
