War on drugs sucks-- talk to your dealer, have him talk to his dealer, and just ask around. Someone up the line from you will inevitably move coke or know someone who does.

Everyone else: If the man wants to do coke, let him. We're not here to lecture him about whatever he wants to put into his body; it's his problem, not ours. That said, if you don't have anything helpful to say, don't say it.

I don't do coke personally, but I know from friends that the gum trick works. Just out of curiosity, what other local anaesthetics could someone add that would be accessible to a drug dealer, and would be as effective as cocaine? Hell, even dentists use coke for anaesthesia!
