Addiction is a brain disorder characterized by compulsive engagement in rewarding stimuli despite adverse consequences. Despite the involvement of a number of psychosocial factors, a biological process—one that is induced by repeated exposure to an addictive stimulus is the core pathology that drives the development and maintenance of an addiction, according to the "brain disease model" of addiction. However, some scholars who study addiction argue that the brain disease model is incomplete and misleading.
