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. They would reportedly put the feces and urine in a jar or a bucket and seal it with a balloon or lid respectively, then leave it out to ferment in the sun; afterwards they would inhale the fumes created . 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 true extent of the practice 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
