The author’s statement does not appear to be supported by his referenced work, nor is it supported by information widely available in the 2004 edition of the Physicians’ Desk Reference (PDR). The referenced article, for example, may demonstrate that modafinil can, in some cases, blunt cocaine euphoria. However, it does not say anything about modafinil’s intrinsic ability to produce euphoria (or not). Separately, the 2004 PDR raises specific concerns about modafinil, saying that it can produce "psychoactive and euphoric effects, alterations in mood, perception, thinking and feelings typical of other CNS stimulants." The PDR also states that "modafinil is reinforcing, as evidenced by its self-administration in monkeys previously trained to self-administer cocaine."
