A southwestern Pennsylvania man called 911 to complain about some terrible marijuana he had just bought, which turned out to be something other than the drug.

Police say the man told officers he bought the substance earlier that day and that "it was nasty" when he smoked it.

Uniontown. Pa. police say a field test determined the substance wasn't pot at all, but police didn't say what it was.

Even though the 21-year-old man didn't technically buy marijuana, he isn't off the hook.and remains under investigation, on a possible charge of possessing a counterfeit controlled substance.
