The alcohol-deprivation effect in monkeys


One stumptail and four rhesus monkeys were given free access to solutions of ethyl alcohol (increasing from 7% to 20% v/v) for 22 days. A subsequent 6 days without alcohol produced a significant increase in alcohol consumption when it was first made available again. Such an “alcohol-deprivation effect” is similar to that previously seen with rats. Unlike the rats, the monkeys frequently appeared to drink to intoxication.
