I was once at a party that someone added Angle Dust into a joint mess up a lot of people at the party, Angle Dust or phencyclidine described as a hallucinogen, dissociative anesthetic, psychotomimetic, and sedative-hypnotic. PCP is a white, crystalline powder (contaminants may cause a tan to brown color), or a clear, yellowish liquid. As a recreational drug, it may be ingested, smoked, inhaled or injected. Even though PCP is known colloquially as “angel dust,” it is likewise referred to as “Ashy Larry,” “illy” or “wet.” The drug is often administered or mixed with other drugs such as crack cocaine, cocaine hydrochloride, and marijuana. Police officers involved argued that King was on phencyclidine, which can make its users seemingly invulnerable to pain. Sergeant Stacey Koon suspected that King was “dusted”—that is, a user of PCP, the drug most feared by police departments. Koon held that the drug made individuals impervious to pain and gave them almost superhuman strength. King’s “buffed out” look added to his apprehensions. Koon concluded that King was probably an ex-con who developed his muscles working out on prison weights.
