Phencyclidine

Phencyclidine (PCP), a clandestinely manufactured hallucinogen commonly used in conjunction with marijuana, causes users to feel detached from their surroundings and, in some cases, paranoid and violent. PCP production is centered in the greater Los Angeles metropolitan area. During the late 1980s and early 1990s, the widespread availability and use of crack cocaine displaced demand for PCP. More recently, however, reporting suggests that PCP abuse is increasing slightly in many cities, as some crack addicts return to the use of this drug. DEA reporting indicates that many large seizures of PCP have occurred in Texas. Every seizure of PCP had originated in the Los Angeles metropolitan area and was primarily destined for Houston.
Since 2000, four major seizures of PCP have occurred in Sierra Blanca, Texas, alone: approximately 6 kilograms of PCP were seized on April 21, 2000; 2 kilograms seized on December 12, 2000; 1,773 dosage units of liquid PCP seized on June 11, 2001; and 33 kilograms of liquid PCP on July 31, 2001. DEA, state, and local authorities also seized four PCP laboratories in 2000 and five in 2001.
