The rematch with Nick Diaz and Carlos Condit was inevitable. Every Diaz fan on the planet rejoiced in the fact that Diaz would have another shot at Condit and have the chance to face Georges St-Pierre in a showdown of all showdowns later this year.

 That was until the news broke Thursday about Diaz failing a drug test with the Nevada State Athletic Commission after his urinalysis came back positive for marijuana metabolites.

Unfortunately for the UFC and all MMA fans, the rematch will not be happening and Diaz’s future goes from being unknown to unpredictable.

 There’s no denying the fact that this is Diaz’s fault, but is the offense that bad? It is not like he took steroids, and anyone that knows anything about Diaz knows that he smokes on a regular basis. He usually quits 10 days out from a fight so he can pass the drug test, but this was unfortunately not the case this time.

 Diaz’s fate will now lie in the hands of the NSAC, but this is where it all gets interesting. Diaz has a prescription for cannabis to treat his Attention Deficit Hyperactive Disorder (ADHD). Rules are rules with the commission, however, and it looks like Diaz’s bad rep will only get worse.

 It is a pretty complicated situation. The guy is getting in trouble for something that he does legally in the state of California, and it’s not as though marijuana helps him perform at a higher level.

 Don’t give me that “jiu-jitsu fighters love to smoke it because it slows everything down” excuse or the “it helps them absorb punishment” one, either. The last time I checked, Diaz has always been able to take a punishment.

What about that Paul Daley fight?

 What is sad is that if Diaz was high during his fight with Condit, he was the aggressor. Yes, I know that Condit threw a variety of kicks and more strikes, but Diaz was the one walking down Condit.

 It is just sad to see one of the most exciting fighters in MMA history fade away right before our eyes. After his less than formal retirement speech given after his fight with Condit, many speculated that he would end up returning to MMA. Who knows now?

 After all, this is Diaz’s second offense, and NSAC executive director Keith Kizer and the NSAC are pretty harsh with their suspensions. Diaz’s first punishment was a six-month suspension he received after failing a drug test for cannabis before Pride 33 in his fight with Takanori Gomi.

 After all of this, Diaz is still immensely popular in the MMA community because he defines the UFC slogan, “as real as it gets.”

 He is what he is, and you can love him or hate him for that. He is not going to say all the right things for the press and pretend to be someone that he is not, and people generally gravitate toward that, both negatively and positively. But if there is one thing we can all agree on it is that he is a fantastic fighter and one of the best welterweights in the world.

 Who knows what Diaz’s future will be in MMA, but for the sake of exciting fights, I’m praying that this is not the last of Diaz.

If Josh Barnett can be popped multiple times for juicing and still compete at the highest levels in the sport, surely Nick Diaz can get a pass for smoking a little reefer with a prescription.
