World's scariest drug: the devil's breath (2012)

While it is occasionally used recreationally for its hallucinogenic properties, the experiences are often extremely mentally and physically unpleasant, and frequently physically dangerous. Ryan Duffy went to Colombia to check out a strange and powerful drug called Scopolamine, also known as "The Devil's Breath." It's a substance so intense that it renders a person incapable of exercising free will. The first few days in the country were a harrowing montage of freaked-out dealers and unimaginable horror stories about Scopolamine. After meeting only a few people with firsthand experience, the story took a far darker turn than we ever could have imagined.
