As a former opiate addict myself, I don't think that's true at all. Moving the choices of addiction from the simple parts of the brain to the higher parts is the whole game. If at any time while I was an addict, you had told me "I'll give you a week's supply, but after that, you can never use again", i'd have made that deal every time, even if I knew it would be enforced.

The problem of addiction is the problem of inter-temporal choice, and a broken discount function. Most addicts don't want to keep using in the executive part of their brain. They know it's self destructive, but they keep doing it anyway, because the next hit is always, in a very local sense, rational. The ability to bind your own hands is the way out.
