The term references a cigarette or marijuana joint that has been dipped in or laced with phencyclidine (PCP). The practice, while not widespread, introduces significant health risks due to the unpredictable effects of PCP.
This method of drug use carries substantial dangers, primarily due to the potent and dissociative nature of PCP. Historically, the substance was used as an anesthetic, but its adverse effects led to its discontinuation for human use. Individuals using substances in this manner risk experiencing hallucinations, paranoia, violent behavior, and long-term cognitive impairment. There are no benefits to the practice.
