Figure 2: Effects of chronic intravenous m-fluoroamphetamine (0.1 mg/kg/hr) administration on choice between cocaine and food in rhesus monkeys (). Abscissae: unit dose of cocaine in milligrams per kilogram per injection. Top ordinate: percent cocaine choice. Middle ordinate: rates of responding in responses per second. Bottom ordinate: number of choices completed. All points represent mean data SEM obtained during the last 3 days of m-fluoroamphetamine treatment. These published data  demonstrate that experimental manipulations can selectively decrease cocaine choice without also decreasing rates of responding and the number of choices completed. This profile would be considered ideal for a candidate medication to treat cocaine dependence.
