Dopamine mediates cocaine-induced conditioned taste aversions as demonstrated with cross-drug preexposure to GBR 12909

► GBR 12909 and cocaine were assessed in the cross-drug preexposure design. ► Cocaine preexposure attenuated cocaine- but not GBR 12909-induced CTAs. ► GBR 12909 preexposure attenuated GBR 12909- and cocaine-induced CTAs. ► Cocaine and GBR 12909 have similar, but non‐identical, stimulus properties. ► The role of DA and other monoamine reuptake inhibitors was discussed.
