Here's one for you. You know how people take deep breaths of their dollar bills and then declare, "This one smells like cocaine," then sigh with exaggerated melancholy? Well, maybe it's not that a surprising percentage of our currency is suffused with the aroma of the coca plant. Maybe, just maybe, cocaine simply happens to smell a lot like our paper money. For all I know, they use byproducts of the coca and hemp plants to make it. I wouldn't put it past them. What better way to catch users than to provoke them into saying, "This one smells like cocaine"?
