Opioids Modulate Rats’ Intakes of Alcoholic Beverages
This chapter summarizes the evidence supporting the conclusion that “opioids modulate rats’ intakes of alcoholic beverages.” The knowledge that a class of drugs affects a complex behavior, such as ingestion, may not be particularly meaningful with respect to determining the chemical coding of the specific behavior in question. A drug could, for example, make subjects ill and, thereby, reduce intakes. Consequently, initial observations of the effects of a class of drugs on a specific behavior need to be elaborated in order to determine the specificity of the effects. With respect to opioidergic effects on intake of ethanol (E), some of that work has been performed, and the outcomes of that work are summarized here.
