Within the depth-psychology corpus, Addiction Medicine names not a settled clinical speciality but a contested site where biomedical authority, humanistic critique, and psychospiritual insight converge and collide. The corpus registers the field primarily through three registers of tension. First, the disease-model debate: Lewis, Dennett, and Alexander interrogate whether the medicalisation of addiction — institutionally consolidated by bodies such as the American Society of Addiction Medicine (ASAM) and the National Institutes of Health — generates genuinely therapeutic frameworks or merely translates moral condemnation into neurological idiom. Second, the pharmacological turn: Avery, Timko, Maté, Addenbrooke, and Hari document and evaluate medication-assisted treatment (MAT) — methadone, buprenorphine, naltrexone — as both evidence-based harm-reduction and as an arena of unresolved ethical and relational conflict between patient autonomy, clinical authority, and institutional inertia. Third, the spiritual dimension: Galanter and colleagues, writing for the International Society of Addiction Medicine itself, argue from within the medical establishment that spirituality constitutes measurable recovery capital and must be formally integrated into clinical protocols. Across these registers, the corpus consistently reveals Addiction Medicine as a field whose explanatory framework shapes treatment outcome, ethical posture, and the very humanity extended to the addicted person.
