Abstract Recent scientific advances have led to a greater understanding of the neurobiological processes that underlie drug abuse and addiction. These suggest that multiple neurotransmitter systems may play a key role in the development and expression of drug dependence. These advances in our knowledge promise not only to help us identify the underlying cause of drug abuse and dependence, but also to aid the development of effective treatment strategies.
