Phencyclidine Confirmation, Urine
Clinical Information: Phencyclidine (PCP) is a drug of abuse. This compound affects diverse neural
pathways and interacts with cholinergic, adrenergic, GABA-secreting, serotoninergic, opiate neuronal
receptors, and gamma receptors. It has analgesic, anesthetic, and stimulatory effects, giving bizarre
behavior, ranging from depression through catatonia, euphoria, violent rage, and hallucinations. Most
fatalities result from its hypertensive effect. Diagnosis of PCP usage depends on drug screen. PCP is
excreted in the urine.
Useful For: Detection of drug abuse involving phencyclidine (angel dust, or angel hair)
Interpretation: The presence of phencyclidine (PCP) in urine at concentrations >10 ng/mL is a strong
indicator that the patient has used PCP.
