Genkhis Genkem

Jenkem is a purported inhalant and hallucinogen created from fermented human waste. In the mid-1990s, it was reported to be a popular street drug among Zambian youth, created by placing feces and urine in a bottle or a bucket, sealing it with a balloon or lid and leaving it to ferment in the sun; afterwards they would inhale the gases generated.
In November 2007, there was a moral panic in the United States after widespread reports of jenkem becoming a popular recreational drug in middle and high schools across the country, though the validity of this claim has since been called into question.
Several sources reported that the increase in American media coverage was based on a hoax and on faulty Internet research.

The name derives from Genkem, a brand of glues which had "become the generic name for all the glues used by glue-sniffing children" in South Africa, where the drug originated and is most popular on the African continent today. In the book Children of AIDS: Africa's Orphan Crisis by Emma Guest, the making of jenkem is described: "fermented human sewage, scraped from pipes and stored in plastic bags for a week or so, until it gives off numbing, intoxicating fumes." The process is similarly described in a 1995 IPS report: "Human excreta is scooped up from the edges of the sewer ponds in old cans and containers which are covered with a polyethylene bag and left to stew or ferment for a week. A 1999 BBC article refers to "the dark brown sludge, gathering up fistfuls and stuffing it into small plastic bottles. They tap the bottles on the ground, taking care to leave enough room for methane to form at the top."
