Abstract: Pharmacological state (or context) and history can direct the expression of learned behavior (e.g., state dependent learning, drug discrimination). Additionally, abrupt drug abstinence can control the expression of learned behavior, a phenomenon that can be defined as behavioral dependence. In this presentation, examples of behavioral dependence will be described and contrasted with physical dependence. In addition, the potential ramifications of behavioral dependence, as well as the implications for regulatory control of drugs, will be considered.
