Various experiments using opioid antagonists have indicated that these drugs cause both humans and animals to decrease their consumption of ethanol. However, it remains unclear exactly which of the endogenous opioids mediates the rewarding effects of ethanol. The present experiment used intravenous self-administration of ethanol to… CONTINUE READING
