Since 90% of U.S. currency contains trace amounts of cocaine, how many notes would you have to snort to get high?
The trace amounts of cocaine bind to the green ink on the bills, so you wouldn’t be able to snort it. Nevertheless, this article quotes an amount:
So if we say there’s 10 lines in a gram, making one line 0.1 grams, and there’s 0.006 micrograms of cocaine on the note, you’d have to snort 16,666,666 notes to get one line of coke. Admittedly I think that amount is one of the smaller amounts of cocaine detected on the bank notes, so maybe if you got a few large amounts it would be higher, but I don’t think it’s going to make that much difference to be honest…!
