Does Modafinil Produce Euphoria?

Other studies (5) have reported that modafinil did not produce amphetamine-like effects and was indistinguishable from caffeine; that, in comparison with methylphenidate and placebo, modafinil "is not an amphetamine-like agent," (6) and that subjects with a history of heavy cocaine abuse could not discriminate the cocaine-like effects of modafinil under controlled conditions.
