Effect of DBH inhibitors on the discriminative stimulus effects of cocaine in rats trained to discriminate 5.6 mg/kg cocaine from saline. Shown is a reanalysis of the data shown in Figure 2 in which the highest dose of disulfiram and nepicastat that failed to nonspecifically suppress response rates based on criteria described in detail in Materials and Methods were identified for each individual subject. n = 8.
