Enhanced Alcohol Self‐Administration after Intermittent Versus Continuous Alcohol Vapor Exposure

Abstract

The finding that intermittent exposure produces more rapid increases in self-administration of ethanol relative to continuous exposure suggests that intermittent exposure may be associated with a more rapid escalation of the allostatic processes responsible for excessive ethanol self-administration. The mechanisms that drive the increases in drinking during withdrawal are similar after 2 and 8 hr of withdrawal and seem to be specific to ethanol.
