More than two dozen people were sickened in an apparent mass drug overdose on a street corner in New York City on Tuesday. The mass overdoses are sparking warnings from police and health officials about the dangers of using K2, also known as synthetic marijuana. Witnesses in Brooklyn reported seeing victims lying on the sidewalk, shaking and leaning against trees and fire hydrants. Thirty-three people were taken to area hospitals with non-life-threatening injuries, police said. It was not immediately clear what drugs the victims had ingested, but police said some of the victims had been smoking K2.
