^^^^^^^^what is sad, is that people... Even after this jon jones fiasco... Still don't realize that nick diaz was right (in asking for his suspension to be overturned). You see diaz had metabolites in his system, but the nevada athletic commission could never prove when it was in his system (because they conduct urine test's, not blood tests)... Thus, his argument that he used those drugs in the out of competition drug phase... Was valid (as pointed out in this video/40:24), since the nac could not prove otherwise...
the real answer to the ts question.... Is that nick diaz's problem wasn't that he used marijuana in too close a proximity to the fight. Instead, it's that he's got the wrong drug of choice (unlike jon jones)... Nac set up a flawed/arbitrary drug policy that persecuted diaz... Its not a coincidence that they raised the thresholds for testing positive.... However, there policy still sucks.... And the ufc... Proved that they are greedy as hell....for not using their code of conduct policies to at least delay the fight (since he was doing coke a month before the fight)...at the very least, they should have released the results...but they feared a backlash, so they sat on it....to cash in on a grudge match ppv... Jaja, dana is so predictable.
