Opioid addiction occupies a contested but richly documented position within the depth-psychology and addiction-studies corpus represented in this library. The passages assembled here resist any single theoretical settlement. Bruce Alexander’s dislocation theory relocates the causal center of opioid addiction away from pharmacological inevitability—challenging the ‘demon-drug myth’ by arguing that withdrawal symptoms are neither necessary nor sufficient to produce addiction, and that heroin’s extraordinary efficacy in relieving emotional anguish makes it peculiarly attractive to the severely dislocated. Gabor Maté approaches opioid use through attachment neuroscience and developmental trauma, situating compulsive opioid use within broader dysregulations of the brain’s endogenous opioid and reward systems. The biomedical literature represented by Avery, Timko, Nabipour, and Stewart foregrounds epidemiology, medication-assisted treatment (methadone, buprenorphine, naltrexone), interoceptive neurology, and public-health frameworks. Avery’s account of the therapeutic community model adds a sociological and rehabilitative dimension, placing opioid use disorder within carceral systems, community reintegration, and identity transformation. A persistent tension runs throughout: whether opioid addiction is primarily a disease of neurochemistry, a symptom of social dislocation, or a failure of relational and nutritional sustenance—with major clinical and ethical consequences for how treatment and recovery are conceived.
