Drug discrimination (DD) is a technique in behavioral neuroscience used to evaluate the discriminative stimulus properties of psychoactive drugs.[1][2][3][4] The discriminative stimulus properties of drugs are believed to reflect their subjective effects.[1] When partial or full stimulus generalization of a test drug to a training drug occurs, the test drug can be assumed to have effects that are subjectively similar to those of the training drug.[2] Drug discrimination tests are usually performed in animals, but have also been conducted in humans.[5][6] Drug discrimination assays have been employed to assess whether drugs have hallucinogen- or entactogen-like effects, among many other types of drug effects.[7][8][9]
