Abstract: 5 pages in length. The motivation for substance abusers to engage in refraining from using drugs is impeded by the neurotransmitter dopamine, the chemical that brings about pleasure. Those with a biological propensity towards drug abuse initially experience enjoyment which then springboards into a greater need for that same dopamine response with each subsequent experience; this constant signaling for more and better pleasure occurs when dopamine travels into a nerve cell cluster underneath the cerebral hemispheres called nucleus accumbens. Bibliography lists 5 sources.
