VICE's Ryan Duffy went to Colombia to check out a strange and powerful drug called Scopolamine (aka "The Devil's Breath") It's a substance so intense 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.

The drug is odourless and tasteless and can simply be blown in the face of someone on the street. Scopolamine completely blocks the formation of memories, and unlike most date-rape drugs, it is virtually impossible for victims to ever identify their aggressors.

"You're like a complete zombie following the people giving you orders." - Scopolamine victim

"In ancient times, the drug was given to the mistresses of dead Colombian leaders -- they were told to enter their master's grave, where they were buried alive." - British Journal of Clinical Pharmacology

"When a patient (of U.S. date-rape drugs) is under hypnosis, he or she usually recalls what happened. But with Scopolamine, this isn't possible because the memory was never recorded." - Dr. Camilo Uribe, world's leading expert on Scopolamine

"From a medical point of view, it's the perfect substance for criminal acts because the victim won't remember anything, and therefore, won't report anything." - Dr. Miriam Gutierez, Faculty of Medicine, National University of Columbia-YT
