The isomers of 3,4-methylenedioxyamphetamine (MDA) functioned as discriminative stimuli in rats trained to discriminate either (-) MDA (1.25mg/kg) or (+) MDA (1.25mg/kg) from saline. Dose- and time-response curves indicated that drug lever selection occurred at doses of at least 1.00mg/kg of (-) MDA and 0.75mg/kg of (+) MDA and that drug-appropriate responding for both isomers was maintained...
