  1. Substance dependence

    Substance dependence is an readaptive state that develops from repeated drug administration, and which results in withdrawal upon cessation of drug use. A drug addiction, a distinct concept from substance dependence, is defined as compulsive, out-of-control drug use, despite negative consequences. An addictive drug is a drug which is both rewarding and reinforcing. ΔFosB, a gene transcription factor, is now known to be a critical component and common factor in the development of virtually all forms of behavioral addiction and drug addictions. Within the framework of the Diagnostic and Statistical Manual of Mental Disorders, substance dependence is redefined as a drug addiction, and can be diagnosed accordingly: Substance dependence can be diagnosed with physiological dependence, evidence of tolerance or withdrawal, or without physiological dependence. The DSM-IV does not use the word "addiction" at all.
