Abstract
There has long been an effort to develop a single unifying theory to explain the phenomenon of drug dependence. Some of these efforts have focused on psychoanalytic theory, various aspects of ego functioning, socio-economic factors, and physiological effects of drugs. Most investigators, however, have focused on character pathology in addicts and have considered addiction as representing one form of character disorder. There has been a lack of emphasis on various psychiatric conditions which could predispose and accompany drug dependence. This author considers drug dependence as a multi-etiological phenomenon. This paper explores various psychiatric problems identified in drug dependent individuals and how they interact with the drug dependence. The use of psychotropic agents in the treatment of drug dependent persons is also explored.
