There is some interesting research distinguishing "wanting" from "liking" behavior that is worth checking out. They are distinct neurochemical processes - addicts may "want" to engage in a behaviour due to dopamine reward circuitry but this is distinct from whether they actually "like" doing this. Animal models have been effective at teasing out the different neurochemical correlates of behavior. https://www.ncbi.nlm.nih.gov/pubmed/27977239 https://www.ncbi.nlm.nih.gov/pubmed/27977239
