water / gatorade for dolution. b complex for color 2 hours before. aspirin 3-4 hours before. Dont chug water weeks before you have the test, it does nothing, the same day up to 4 hours before is what gets you the negative thc result. aspirin fucks with the testing and they can't do anything about it. It used to give a false positive for ibeuprofin, they changed that. :rasta:
