Effects of continuous 7-day treatment with m-fluoroamphetamine (0.032–0.32 mg/kg/h) on choice between cocaine and food. Upper vertical axes: percent cocaine choice (left) or the number of choices completed per component (right) during treatment with saline (Baseline) or increasing doses of m-fluoroamphetamine. Upper horizontal axes: unit dose of cocaine in milligrams per kilogram per injection. Bottom panels show total choices, food choices, cocaine choices and cocaine intake during choice sessions before or during 7-day treatment with m-fluoroamphetamine. Lower left vertical axis: Number of choices per session. Lower right vertical axis: cocaine intake in mg/kg/day during choice sessions. Lower horizontal axes: experimental endpoint. All points and bars represent mean data ± SEM from four monkeys obtained during the last 3 days of each 7-day treatment. Filled symbols indicate significantly different (p < 0.05) from baseline conditions within a cocaine dose. Asterisk indicates significantly different (p < 0.05) from baseline conditions.
