PCP

Timeline

by Erowid

1926		Phencyclidine (PCP) is first synthesized. 1
mid 1950s		Parke Davis begins investigating PCP as a human anesthetic. 2
1957		PCP tested for the first time on 64 human subjects. Worrying side effects such as hallucinations, mania, delirium and disorientation manifested. 2 [Details] The study was published in 1958 by FE Greifenstein as "A study of a l-dryl cycle hexyl amine for anesthesia", Anesth Analg 37(5): 283-294.
1963		PCP is patented as a surgical analgesic and anesthetic under the name 'Sernyl'. 3
1965		PCP is withdrawn for use on humans because of reports of the negatives effects caused by its use. 3
1967		PCP is marketed under the name Sernylan as a tranquilizer and anesthetic for animals. 3
1967		PCP shows up on the street as a recreational drug under a variety of names including 'angel dust', 'hog', 'super-weed', and 'THC'. Because it is inexpensive and relatively easy to make it is frequently marketed and sold as other substances including Cocaine, LSD, and THC. 2
Apr 6, 1969		PCP was placed under DACA control in the United States, making it illegal to possess, sell, or manufacture except for personal use. 4
Nov 1969		DEA's forerunner, the Bureau of Narcotics and Dangerous Drugs, reports in their Microgram newsletter: "Phencyclidine HCI impregnated on plant material and promoted as 'Hog' was recently analyzed by our Washington Regional laboratory. The evidence was seized in Virginia, and a localpolice department states that the term 'Hog' has been used in the area for alleged 'THC', reportedly mixed with strychnine."
Early 1970s		PCP is placed in schedule III of the Controlled Substance Act.
1973 - 1975		Use of PCP spreads quickly in the U.S. 2
1978		PCP is moved from schedule III to schedule II of the Controlled Substance Act. 5
1979		7 percent of high school seniors report having used PCP in the last year. 6 [More Info]
1980 - 1995		The use of PCP among high school students steadily declines between 1979 and and the mid 1990s. 6 [More Info]
2010		Five percent of men arrested in the District of Columbia test positive for PCP. 7 [Details] Among the ten U.S. metro areas surveyed by the Arrestee Drug Abuse Monitoring Program (ADAM) of the Office of National Drug Control Policy, Washington's rate of PCP-positive urinalysis screening is unique. In the other cities evaluated in the report, PCP is 'barely detected' among arrestees. MDPV can trigger false positives for PCP in urinalysis. Whether this was a factor in D.C. in 2010, a year when MDPV-containing 'bath salt' products are just beginning to show up in the U.S., is impossible to determine.
