Discriminability from the nondrug condition constitutes a recently discovered attribute of drugs. One of the early findings (Overton, 1966) was that rats trained to discriminate pentobarbital from the nondrug condition chose the drug response in tests with several other sedative-hypnotic drugs (phenobarbital, ethyl alcohol, ethyl carbamate) and also with anti-anxiety agents (chlordiazepoxide, meprobamate). This indicated similarity among these drugs with respect to stimulus attributes.
