Disease model of addiction
The disease model of addiction describes an addiction as a disease with biological, neurological, genetic, and environmental sources of origin. The traditional medical model of disease requires only that an abnormal condition be present that causes discomfort, dysfunction, or distress to the individual afflicted. The contemporary medical model attributes addiction, in part, to changes in the brain's mesolimbic pathway. The medical model also takes into consideration that such disease may be the result of other biological, psychological or sociological entities despite an incomplete understanding of the mechanisms of these entities.
Critics of the disease model, particularly those who subscribe to the life-process model of addiction argue that labeling people as addicts keeps them from developing self-control and stigmatizes them. As noted by the harm reduction specialist Andrew Tatarsky:
|“||The essence of this model is the pragmatic recognition that treatment must meet active substance users ‘‘where they are’’ in terms of their needs and personal goals. Thus, harm reduction approaches embrace the full range of harm-reducing goals including, but not limited to, abstinence.||”|

"DESPITE THE IMPORTANCE OF NUMEROUS PSYCHOSOCIAL FACTORS, AT ITS CORE, DRUG ADDICTION INVOLVES A BIOLOGICAL PROCESS: the ability of repeated exposure to a drug of abuse to induce changes in a vulnerable brain that drive the compulsive seeking and taking of drugs, and loss of control over drug use, that define a state of addiction. Here, we review the types of molecular and cellular adaptations that occur in specific brain regions to mediate addiction-associated behavioral abnormalities. These include alterations in gene expression achieved in part via epigenetic mechanisms, plasticity in the neurophysiological functioning of neurons and synapses, and associated plasticity in neuronal and synaptic morphology mediated in part by altered neurotrophic factor signaling.
