Outline
Circulating message claims that criminals are placing $100 bills laced with a debilitating chemical on cars as a means of making drivers who touch the note pass out so that they can be kidnapped or assaulted.
Brief Analysis
The warning is a hoax. There are no credible reports about attacks like the one described. Moreover, it is extremely unlikely that there is a chemical so powerful that merely touching a laced note would make a person pass out. The message is derived from older urban legends claiming that fake perfume or business cards laced with powerful drugs have been used to debilitate and rob or kidnap victims.
