The Smoking Gun reports that the sheriff's intelligence bureau in in Collier County, Florida issued a warning to be on the lookout for a dangerous recreational drug called "jenkem," made from fermented human waste.
A quick search on the rumor busting site Snopes.com would have saved the bureau from embarrassment.
From Smoking Gun:
It's an inhalant called "Jenkem," and causes hallucinations and a "euphoric high." Of course, as the bulletin notes, Jenkem users dislike its sewagey taste, which can last for days. That's because Jenkem's active ingredients are urine and fecal matter, hence its street names like "Butthash" and "Fruit from Crack Pipe."
