HOAX – ‘Chemical Laced $100 Bills Placed on Cars to Kidnap Drivers’

This story was first published on September 1st, 2014


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.


Came out the store with my sister and this was on my car! I climbed in from the other side she drove us through a car wash so we didn’t touch it! The rumors going around are people putting 100 on your car with chemical to make you pass out so they can kidnap you hurt you and take your car! Females watch this I thought it was a joke. Well it just happened to us so we drove around until we seen no one from the parking lot anymore.

Detailed Analysis

Message Warns of Laced $100 Bills Used in Car Park Kidnappings

A post currently circulating via social media warns that criminals are using $100 bills laced with a powerful chemical as a means of debilitating and kidnapping victims.

The message claims that the laced $100 bills are being left on car door handles so that, when the victim returns to the vehicle, he or she will touch the bill and then pass out. Then, the criminals can kidnap or hurt their victim and steal the car.

Or so the ‘warning’ message would have us believe.

Warning is a Hoax – No Credible Reports of Such Crimes

But, in fact, the message is just a silly hoax and its claims are untrue.

There are no credible news or police reports about crimes like the one described in the message.

Moreover, the message immediately makes you wonder what chemical would be so powerful that just touching it would knock out the victim instantly. In fact, I could find no references to such a chemical. Of course, there are drugs that, if swallowed or inhaled may cause dizziness and debilitation. But, there is no information about a drug that can immediately render a person unconscious just by touching an object that contains it.
To work, the chemical would have to either give off fumes that the victim breathed in or be absorbed into the body via the skin. It is simply absurd to suggest that, just by picking up a note, enough of the drug could be administered by either of these methods to instantly render a person unconscious.

And, if there were such a substance, how would the criminals manage to lace the $100 bill and plant it on the car without being affected themselves? Wearing thick gloves and breathing apparatus while planting laced notes on cars might look a trifle suspicious.

Furthermore, why would the criminals use hundred dollar bills when they could just smear the substance on a piece of paper – or the door handle itself – and presumably achieve the same result? Hundred dollar bills – even fake ones – would be quite conspicuous and would likely be noticed and perhaps even snatched by passers-by.

Variant of Earlier Urban Legends

This warning is clearly derived from earlier urban legends that also falsely claim that criminals are debilitating and robbing people by getting them to sniff fake perfume or take a business card.

The message is also reminiscent of another circulating warning that claims $100 bills are being left on windshields as part of a car-jacking scheme. Supposedly, a hapless shopper will get in the car, notice the $100 bill and then get out to retrieve it. The criminals can then pounce from hiding and steal the car and possibly even abduct the car’ driver. But again, there are no credible reports that support the claim that car thieves are using this rather unlikely tactic. And, this warning is itself derived from yet another urban legend that claimed that criminals were putting pieces of paper on the rear windows of cars as a means of stealing them.

Passing on False Warnings Counterproductive

Sharing these false warnings will help nobody. Such messages do nothing other than pointlessly spread fear and alarm and make it less likely that genuine warnings are taken seriously.

If you receive one of these warnings, do not share it with others. And take the time to let the sender know that the claims in the message are untrue.

Importance Notice

After considerable thought and with an ache in my heart, I have decided that the time has come to close down the Hoax-Slayer website.

These days, the site does not generate enough revenue to cover expenses, and I do not have the financial resources to sustain it going forward.

Moreover, I now work long hours in a full-time and physically taxing job, so maintaining and managing the website and publishing new material has become difficult for me.

And finally, after 18 years of writing about scams and hoaxes, I feel that it is time for me to take my fingers off the keyboard and focus on other projects and pastimes.

When I first started Hoax-Slayer, I never dreamed that I would still be working on the project all these years later or that it would become such an important part of my life. It's been a fantastic and engaging experience and one that I will always treasure.

I hope that my work over the years has helped to make the Internet a little safer and thwarted the activities of at least a few scammers and malicious pranksters.

A Big Thank You

I would also like to thank all of those wonderful people who have supported the project by sharing information from the site, contributing examples of scams and hoaxes, offering suggestions, donating funds, or helping behind the scenes.

I would especially like to thank David White for his tireless contribution to the Hoax-Slayer Facebook Page over many years. David's support has been invaluable, and I can not thank him enough.

Closing Date

Hoax-Slayer will still be around for a few weeks while I wind things down. The site will go offline on May 31, 2021. While I will not be publishing any new posts, you can still access existing material on the site until the date of closure.

Thank you, one and all!
