New High or Hoax?
From ABC News:
Police in Naples, Fla., are on the lookout for users of "jenkem," a homemade drug created by allowing human urine and feces to ferment in a bottle with a balloon covering the opening. Users inhale the released methane gas from the balloon to get a "euphoric high similar to ingesting cocaine, but with strong hallucinations of times past," according to a Collier County Sheriff's Office bulletin.
The downside: "Subjects who used the jenkem disliked the taste of sewage in their mouth and the fact that the taste continued for several days."
