The effects of haloperidol on cocaine-induced conditioned taste aversions

► The DA antagonist, haloperidol, was assessed for its aversive effects. ► Active (but non aversive) doses were then given before CTA training with cocaine. ► Under these conditions, haloperidol attenuated cocaine-induced CTAs. ► These results suggest that DA is involved in cocaine's aversive effects. ► These findings were discussed in relation to work investigating other systems.
