So you're posting something which
asserts the disease model of addiction. Well, thanks for that. It's very even-handed of you.
The "disease model" of substance addiction, and the extension of the medicalized notion of addiction to other compulsive behaviors such as compulsive gambling and compulsive sex, is another way in which brain-based explanations of behavior have impacted society. The disease model emphasizes the deterministic and physiological nature of the behaviors and thereby reduces their moral stigma.
Which is precisely what people who use the disease model as a
therapeutic tool have said since umm 1935. It's not about whether it's objectively true, it's about whether it works in treatment.
