<P> 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 which is induced by repeated exposure to an addictive stimulus -- is the core pathology that drives the development and maintenance of an addiction . The two properties that characterize all addictive stimuli are that they are reinforcing ( i.e. , they increase the likelihood that a person will seek repeated exposure to them ) and intrinsically rewarding ( i.e. , they are perceived as being inherently positive , desirable , and pleasurable ) . </P>
