PCP, once common, is no longer being legally manufactured. It is illegally manufactured and sold on the street under names such as angel dust; it is sometimes sold in combination with herbs, marijuana, and tobacco.
Intoxication, characterized by a giddy euphoria, occurs with lower doses; euphoria is often followed by bursts of anxiety or mood lability.
Overdose causes a withdrawn state of depersonalization and disassociation; when doses are higher still, disassociation can become severe and response to external stimuli is impaired, with combativeness, ataxia, dysarthria, muscular hypertonicity, nystagmus, hyperreflexia, and myoclonic jerks. With very high doses, acidosis, hyperthermia, tachycardia, severe hypertension, seizures, and coma may occur; deaths are unusual.
Acute effects generally fade rapidly and many patients regain normal consciousness in 45 minutes to several hours.
