In the past, addiction was viewed as stemming from an individual’s moral failing and weakness of will
With the advances in scientific research, biological theories of addiction as a “brain disease” are now widely accepted; however, this point of view is still controversial.
The disease model is supported by the changes that occur in the brain as a result of continued substance use. Through a process of adaptation, the brain attempts to adapt to the presence of a substance in effort to function normally. The disease model asserts that while initial choice to use the substance may have been voluntary, over time behavioral choice is lessened as these neurobiological changes occur.
