Behavior.

The awareness of many factors involved in drug abuse, such as initial stages, maintenance, cessation, and relapse, has improved because of the behavioral studies.
The creation of the self-administrator model and its use to assess abuse liability and deepen our understanding of addiction have been the main contributions of behavioral research to the study of drug abuse. Other models based on the principles of learning and conditioning have been added to this basic model.

These models include drug classification, behavioral economics’ relationship between drug use and parameters controlling use; the nature of drug abuse’ phases of transition (initiation, abstinence, withdrawal); motivational states, as well as the roles of tolerance and physical dependence in drug-seeking conduct (Drug Abuse Research, 1996).
