The NY Times recently had a Room for Debate feature on addiction. They published opinions from 6 different people on addiction with one being a clear advocate for the disease model. This is a little like publishing a debate feature on climate change and having 1 of 6 experts believe that global climate change is occurring.
It’s well established that addiction is a disorder of the pleasure pathways. When other parts of the brain (related to, say, vision or movement) or other organs experience disorders, we don’t devote NY Times features to whether they really are a disease or whether choice is a factor in the illness. However, when pleasure enters the picture, we have a very difficult time surrendering the notion that we are, or should be, in full control of our behavior.
Kevin McCauley addresses the role of pleasure in advocacy for the choice argument:
Addiction is a disorder of the brain’s ability to properly perceive pleasure. I think it’s this moral loading of pleasure that makes it harder to accept that this is a disease process. It’s easier to just write addicts off as bad people who just want to feel good. In fact, that’s a corollary of the choice argument. It says exactly that, “Addicts don’t shoot gasoline into their veins, they shoot drugs into their veins! And, why? Because it feels good. Addicts do it because it feels good!”
In fact, there’s a sentence in the AA big book that says basically the same thing, “Men and women drink essentially because they like the effect produced by alcohol.” And that’s exactly right. What addiction is, is a defect in the brain’s like mechanism. Pleasure is the capacity of the brain, and being a natural organ, the brain can break. And, addiction is, at it’s heart, a broken pleasure sense.
