The Nick Diaz marijuana fiasco just won't seem to die. Following his loss to Carlos Condit at UFC 143, Diaz popped positive for marijuana metabolites, his second such positive test in Nevada. The aftermath of the positive test saw a number of reactions from calls that Diaz be released from his UFC contract to people saying that Diaz's "need" for the drug and the fact that the testing is pointless should result in little to no punishment for Nick.

Speaking at the UFC 146 press conference yesterday, UFC president Dana White suggested that there really is no excuse for Diaz's positive test (via MMA Weekly):

"My stance on the whole thing is... it's not allowed. You're not allowed to do it. Whatever the commission says you're not allowed to do, you're not allowed to do. It doesn't matter what I think," UFC president Dana White stated in a meeting with reporters following Tuesday's UFC 146 press conference in Las Vegas.

"I don't smoke weed. It's not my thing. It's illegal; you can't do it. I can't present an argument for why (Nick Diaz) should be cool to have marijuana in his system."

I have to agree with Dana here, it seems like there has been a lot of playing with words and situations but very little looking at the most basic fact of all: Diaz tested positive for a substance you're not allowed to have present in your body. Regardless of if he checked yes or no to "have you used a prescription drug" on the fighter application, regardless of if technically he does or doesn't have to have a prescription for marijuana in California, it's not something you can have in your system.

Diaz didn't bother to apply for an exemption and it's not like he hasn't flaunted an ability to "beat the tests" frequently in the past. It's strange to me that this has become a sob story for Nick.

Is the testing dumb? Yeah, a little bit. But it's still in place and passing those tests is a requirement to the privileged (again, professional fighting licenses are not a right) of being allowed to fight. If Nick is, in fact, so desperately in need of pot to get through his day to day life, there are procedures in place to request an exemption. They did not try to do this. Even if it likely would have been denied, it is still the correct first step in this situation.

You can't simply use whatever you want, ignore the rules of having a pro fight in Nevada and then, once you're caught, suddenly act like the victim. It just doesn't work like that.
