but in theory, if u have a tiny cut on your hand, and you touch a bill, you have the same risk of catching HEP C dont you? Although yes, it is stupid to use currency for snorting, god knows where each and every dollar has been.. i guess using currency to insufflate is so deep-rooted in the drug culture, that most people ive ever seen snorting coke, for example, in any country, have used money. its partially an ego thing (people using $100 bills to snort coke, thinking it makes them look cool), but yeah its a bad habit.
