substance intoxication
a reversible syndrome due to the recent ingestion of a specific substance, including clinically significant behavioral or psychological changes as well as one or more signs of physiological involvement. Although symptoms vary by substance, there are some common manifestations: for example, perceptual disturbances; mood changes; impairments of judgment, attention, and memory; alterations of heartbeat and vision; and speech and coordination difficulties. DSM–IV–TR and DSM–5 identify 10 drug classes associated with intoxication: alcohol, amphetamines, caffeine, cannabis, cocaine, hallucinogens, inhalants, opioids, phencyclidines, and sedatives, hypnotics, or anxiolytics.
