A small device was demoed to me that could accept an object and report if it had cocaine on it. The officer asked for a dollar, I handed him one, and they put it in.

The machine detected cocaine. I was surprised to learn that the powder is so fine it's on nearly all US paper money.

How is this measured? The concentrations seem so small. Are we sure the readings are accurate?

What if the cocaine is actually there as a secret anti counterfitting measure?

It’s in the ink. One of the ways you can tell a US bill is authentic is by licking it. If your tongue or gums go numb then it’s definitely not counterfeit.

Yikes, given how dirty paper money is I wouldn't lick it.
