i know to test coke u put a little bit on ur gum or tonuge and if it numbs it its good coke, or atleast some wat decent coke, but how much i mean is it just like 1 or 2 little chrystals or is it as much as the tip of ur finger or wat?
i dont know for sure... but when i found a bag one time that almost empty it didnt take much to numb my tongue, that might have been good shit though. just a little on your fingertip should do if you really wanna test it. and man you shouldnt fuck with that shit, be careful!
Just put a little bit of powder spread across your gums. It's kinda fun actually, when they become numb, and you get a very slight buzz. Like, you won't notice it's there much, but you'll notice when it's gone.
thats not a test for good coke at all. coke dealers often cut their shit with lidocaine or benzocaine which will numb your gums easily even though theres very little coke in it. the best way to test and see if its good is to blow a single line and wait a few minutes. most of your face should go numb and you will be high.
