Is Addiction a Disease? The current medical consensus about addiction may very well be wrong

The prevailing wisdom today is that addiction is a disease. This is the main line of the medical model of mental disorders with which the National Institute on Drug Abuse (NIDA) is aligned: addiction is a chronic and relapsing brain disease in which drug use becomes involuntary despite its negative consequences.  

. . . 

Yet, though there are positive aspects to seeing addiction in this light, it seems unduly pessimistic and, though no one will deny that every behavior has neural correlates and that addiction changes the brain, this is not the same as saying that, therefore, addiction is pathological and irreversible.

And there are reasons to question whether this is, in fact, the case.
