title: Reduction of heroin intake in baboons by an economic constraint.
abstract: Baboons earned their total food ration in a situation where they were periodically given an opportunity to choose between food and an intravenous infusion of heroin. As the number of daily choices was restricted, food intake remained relatively constant, while heroin intake decreased dramatically.
