I've read similar reports in email chains in the 2000. Like the guy that touched a piece of paper and a few seconds later collapsed. I think that some local newspaper even published it, without evidence.

From the NYT article:

> She carried it from a restaurant counter to their table. He had two spoonfuls, Mr. Valdez, 31, said. “And that’s the last thing I remember.”

> He drank a pink soda, he said in a video, and later awoke to find his wallet and phone gone.

> One 42-year-old man from New York recalled being drugged by a Tinder date who served him a rum and coke that he said knocked him out for 24 hours.

These case makes more sense. There are a few recent similar cases here, and many buildings have security cameras on the front door, so they get a nice video of the escaping thieves.

Yah I think there's a lot of urban legend around the stuff. I know a few people who have used it (well, Brugmansia plants that contain it anyways) as part of their apprenticeships (Amazonian plant medicine, in conjunction with ayahuasca) in a more controlled manner and even then they have some wild stories about it (waking up naked in the jungle, covered in scratches with no memory etc). It lasts a looong time.
