Like a lot of illicit substances, scopolamine actually has some beneficial uses and has even been used by NASA as an anti-nausea medication (though this may just be a convenient cover for some of the more hard-partying astronauts). Derived from the nightshade family of plants, it's also quite handy for anesthesia recovery, irritable bowel syndrome, and the treatment of Parkinson's disease. But scopolamine isn't all about firmer poops and seasickness cures. One rather ominous nickname for it is the Devil's breath. And an even scarier one is the most dangerous drug in the world, because it's just fantastic for when you want to rob people and/or turn them into your personal zombie-slaves.
Although scopolamine in its most processed form looks exactly like cocaine, it's not really for recreational purposes. Well, unless your idea of fun is to blow mind-control powder into the faces of unwitting victims to make them do your evil bidding. Scopolamine is reportedly popular among criminals in Colombia who spike the drinks of unsuspecting dupes or simply blow it onto them voodoo-style. Then, once the drug has achieved the desired effect of rendering those same dupes highly susceptible to suggestion, it's time to lead the victim over to the nearest ATM to empty out their bank account or make them happily agree to whatever other nefarious activity springs to mind. Like forcing you to play Superman 64.
The above image comes from an interview with a woman who claims to have actually engaged in these kinds of crimes. There have been some overblown examples of the powers of scopolamine out there, but as ridiculous and urban-legendary as falling prey to an attractive lady who's smeared a zombie drug all over her boobs sounds, it's apparently enough of a possibility that the Department Of State felt the need to issue a warning.
