Bupropion perceived as a stimulant by two patients with a previous history of cocaine misuse.

Despite animal studies having shown a generalisation of the bupropion cue to cocaine, this drug has been used in cocaine abuse with mixed results. We here aimed at describing two cases which contradict current knowledge.We describe two cases of former cocaine abusers who reported a cocaine-like sensation upon taking bupropion. Bupropion improved patients' depression without any increase in cocaine craving. One of the patients increased without doctor consultation his dose on an as needed basis.The issue of bupropion cue generalisation to cocaine needs further elucidation. People with past cocaine addiction need to be informed on the potential of bupropion to elicit cocaine-like cues and be invited to adhere to medical prescription, because bupropion has been associated with fatalities in some cases.
