Below I repeated the contention that while schizophrenia is a genuine biologically rooted behavioral disease which can not be cured through will, many forms of addiction are not. That is why the genetics of schizophrenia are of such great interest, if the biological pathways of the pathology can be elucidated presumably a cure may be found. Unfortunately finding the genes is easier said than done, see Schizophrenia: The Mystery of the Missing Genes.
