A deadly drug which can turn people into zombie-like creatures, eliminate free will and wipe memory is being sold on the streets of Colombia.
Scopolamine, known as "the Devil's Breath", is considered the world's scariest drug.
Experts are warning that even though it looks like cocaine, and is also made from plants, scopolamine is not a recreational drug.
In a new documentary, which has gone viral since it aired on Vice.com, reporter Ryan Duffy travels to the South-American country to find out more about the powerful drug.
During the 36-minute documentary titled Colombian Devil's Breath, he investigates the stories behind the drug, its involvement in organised crime, and its impact on the body and mind.
Among the abundance of tales surrounding the drug are stories of people being raped, forced to empty their bank accounts, and even coerced into giving up an organ.
A drug dealer in the capital Bogota told Duffy just how easily the odourless and tasteless drug can be administered by criminals.
He revealed that victims can be drugged within minutes if it is blown in their face by a passerby on the street.
"You wait a minute and when you see it kick in, then you know you own that person.
"You can guide them wherever you want. It's like they're a child," he said.
In the video, Duffy also talks to those who have fallen victim to the drug, which is lethal in high doses.
One woman revealed that she had come into contact with the drug after a man approached her on the street asking her for directions.
After sharing a drink with the man, she was drugged and helped him rob her of all her worldly possessions.
"It is painful to have lost money. But I was actually quite lucky," she said.
The documentary also features a 21-year-old prostitute who admits to using scopolamine on her clients to rob them. Once drugged, she says that the men readily gave up their bank access codes.
Although Duffy manages to get his hands on the drug by the end of the documentary, he backs out of his original plan to sample it.
Speaking to the camera, he explains: "The original plan was for me to sample the drug myself to really get an idea of the effect it had on folks.
"All elements of humor and novelty were rapidly stripped away during my first few days in town. After meeting only a couple people with first-hand experience, the story took a far darker turn than we ever could have imagined."
