what's a way to get crack cocaine out of your system.
not smoking it to begin with ;)
other than that you just have to wait it out...most tests nowadays test for masking agents, so there's no real way to mask it to trick the test. check out www.erowid.org for more information
You need your dad to help you. First you tell your dad you did cocaine and then he will warm up his leg and kick your asset so much it wont be a problem anymore :)
