Good cocaine doesn't destroy your mucous membrane inside your nose. It's not burning like hell, so that the tears are rolling down your cheeks, no!
Ant it never makes your nose, your mouth, your teeth totally numb. That does Lidocaine. Good stuff makes not really numb - and it should not burn (like the last i have) until your front tooth are aching so that you're in panic search for any pain killer. I'm no pussy, but I really cried. The stuff itself was great but there was too much kerosine. Very painful thing.
