This week VBS heads back to Bogota for a look into the terrifying world of Scopolamine — an anti-nausea drug sometimes used for sea sickness or as a pre-anesthetic, that in slightly higher doses basically obliterates your free will and turns you into a living zombie.

If you’re American, you may remember it as the drug used to cut the “Blue Velvet” flavor of Nuke in Robocop 2, but if you’re from Colombia, odds are you’re on slightly more intimate terms with the genuinely heinous effects of Scopolamine, or its indigenous plant form burundaga. That’s because its use in the criminal underground there, where random victims are scoped up and then converted into human ATMs and/or instant prostitutes, has reached critical proportions and accounts for nearly half of all poisonings treated in Bogota. It is quite literally the stuff of nightmares.
