amphetamine abuse
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, however, both have been combined into one category, stimulant use disorder, and are no longer considered distinct diagnoses. See also substance abuse.
