An experiment was performed to determine if the discriminative stimulus effects of morphine are modified by mild food deprivation, a condition that increases drug-reinforced behavior. Rats were trained to discriminate between SC injections of saline and morphine (3.0 mg/kg) in a discrete-trial shock-avoidance procedure. Stimulus generalization curves for morphine were then determined on three occasions by a cumulative-dosing procedure: before, during and after the body weight of the rats had been reduced to 86-87% of normal by restricted feeding. Food deprivation had little or no effect on the morphine generalization curve. Despite a close relationship between the reinforcing and discriminative stimulus properties of opioid drugs, stimulus control of behavior by morphine was not modified by a condition that enhances opioid-reinforced behavior.
