Agreed. This paper https://www.nejm.org/doi/10.1056/NEJMra1602872 (which isn't available open access, unfortunately) argues that the brain changes in substance use are more likely normal learning associated with very strong stimuli than actual disease processes. I find this to be a more helpful, optimistic, and accurate interpretation of the data than the disease model. (And it really complements the other evidence-based interventions for substance use disorders we have!)
