APA Dictionary of Psychology

in DSM–IV–TR, a pattern of use of amphetamines or amphetamine-like substances that is marked by recurrent significant adverse consequences related to the repeated ingestion of these substances. This diagnosis is preempted by the diagnosis of amphetamine dependence: If the criteria for amphetamine abuse and amphetamine dependence are both met, only the latter diagnosis is given. In DSM–5 and DSM-5-TR, however, both have been combined into one category, stimulant use disorder, and are no longer considered distinct diagnoses. See also substance abuse.
