Which MMA Fighter Will Test Positive For Steroids Next?

[UPDATED] Diaz’s UFC 143 Drug Test Positive for Marijuana; Fighter Now Faces NSAC Disciplinary Action

By Mike Russell

We know the suspense has been killing you, so we’re just going to break it to you.

Apparently Nick Diaz partook in the stick icky a little too close to his UFC 143 welterweight interim title bout with Carlos Condit as the Nevada State Athletic Commission has announced this afternoon that the Stockton native’s post-fight urinalysis came back positive for marijuana metabolites.

According to NSAC executive director Keith Kizer, 18 of the 22 fighters who competed on Saturday night’s card were tested and only Diaz yielded a positive result.

Carlos Condit, Fabricio Werdum, Josh Koscheck, Renan Barao, Ed Herman, Dustin Poirier, Max Hollaway, Matt Riddle, Henry Martinez, Edwin Figueroa, Alex Caceres, Matt Brown, Chris Cope, Rafael Natal, Michael Kuiper, Stephen Thompson and Dan Stittgen were also tested.

Here’s what Kizer wrote in the email statement we received:

“All results received thus far have been negative, except Mr. Diaz tested positive for marijuana metabolites,” he revealed. “A complaint for disciplinary action against Mr. Diaz has been filed.”

Nick, who has a prescription for cannabis to treat his ADHD has stated in the past that he smokes up to ten days out from his bouts and that his metabolism rids the drug from his system in that little time.

“I’m more consistent about everything being a cannabis user,” Diaz said in an interview with The LA Times back in April 2009 ahead of his Strikeforce fight with Frank Shamrock. “I’m happy to get loaded, hear some good music . . . I remain consistent. And I have an easy way to deal with [the drug tests]. I can pass a drug test in eight days with herbal cleansers. I drink 10 pounds of water and sweat out 10 pounds of water every day. I’ll be fine.”

The problem is that he’s getting older and his metabolism is slowing down — that and sometimes the metabolites can stay in the system for weeks after a person has stopped using since they are fat soluble.

Here’s an explanation of why commission drug tests should only be done by blood, courtesy of’s The ABCs of Marijuana and Drug Testing:

“Urinalysis can not detect the presence of any illicit drugs – including marijuana – and can only identify the presence of non-psychoactive drug metabolites indicating that a substance has been previously consumed at an unspecified point in time. Unfortunately for cannabis consumers, pot’s primary metabolite THC-COOH is fat soluble, and may remain detectable in urine for days and sometimes two-to-three weeks after past use in regular smokers.

Blood tests, unlike urinalysis, detect the presence illicit drugs, not inactive drug metabolites. In general, THC only remains detectable in the blood of cannabis consumers for a few hours (though low, residual levels may be detected in chronic smokers for up to 12-24+ hours if more sensitive technology is used). Because of this narrow detection window, blood tests are typically only administered in the workplace post-accident in order to estimate recent cannabis consumption.”

Since this is Nick’s second offense, it’s unlikely that he’ll be able to dispute the charges against him, even if he took a lie-detector test like Sean Sherk to prove that he didn’t smoke for a week or so before the bout. I guess we’ll have to wait and see what he or Cesar Gracie have to say about the charges.

I’m not advocating for fighters who do drugs, but it seems unfair that by rights a fighter could get drunk a day or two before a fight if they so desired, but smoking pot a week or two before a fight when they have a prescription to do so and when the commission doesn’t actually test for THC,  only inactive metabolites, is a punishable offense.

I think it has more to do with the stigma involved with the substance, more than it does the act of using it, especially when it isn’t illegal for the fighter to do so while he isn’t fighting.

Last time he received a six-month suspension when he tested positive after his PRIDE 33 bout with Takanori Gomi. The bout was also declared a no-contest. Hopefuly the result from his bout with Condit stands, or else we may have to have another welterweight interim title fight soon.

*UPDATED Feb. 8, 2012 at 8:00 pm ET: UFC president Dana White released the following statement about Diaz’s positive test this evening:

“I am beyond disappointed that he tested positive for marijuana. It is now in the hands of the Nevada State Athletic Commission.”

Hahaha, that is hilarious....smoke chronic
intercept440- February 10, 2012 at 7:12 pm each his own. i respectfully disagree though son...ive lived in nevada my whole life...the NSAC is the equivelant of the NGC (nevada gaming commision). they dont compromise on thier rules, end of story,assholish as it may be.
i mean think about it. if the NSAC gave a frog's fat ass about what the fans thought, why in the BLUE HELL would cecil peoples be even allowed to attend a sport let alone judge one. how many fucking fights has that cuntflap fucked up. yet low and behold that fucker is always a judge.

See, that's funny right there. That's a good response.

@dranokills: Little did I know that my alias was so transparently indicative of my love affair with Diaz, my seven year addiction to cheap cocaine, my illiteracy and finally my irrational fear of surprise throat attacking squirrels. Ha! Try posting a constructive and relevant response you big butthurt eejit.

@intercept440: Every overturned policy begins with discontent, indeed oft vocalized as a complaint. You dig brah? The complaint is the seed. The subsequent amending of policy is the flower. Circle of life brah. Regarding the dollar, here's the best rebuttal I've found (no point in paraphrasing): "Diaz is right. There are boxers out there, guys like Adamek, Green, even Pavlik who made or make way more than Diaz.If you are to believe the PPV and gate numbers pumped out by Meltzer, then these guys are underpaid in relation to the gross overall gate and PPV. If boxing is dead, how can guys like Green nab $5 million for a fight and he is nothing like a household name in America. And then there is Diaz who is in then P4p discussion, a main event fighter on a PPV and he is getting chump change."p

dranokills- February 10, 2012 at 4:44 pm
ha. Is it any wonder that someone named darkstarrocketship would be a fan of Diaz? Is it any shock that this moron would post like a 7 year on crack? no.
Does it shock anyone that said person bitches about needing an edit button when it is obvious he cannot form a proper sentence? No, but the irony of this is funny as hell.
Btw darkstarrocketship....... SQUIRREL!!!!!
made ya look.

@dranokills If you have 0 experience on something, don't comment on it. How do I know you have 0 experience? "Just cause a muthafucka is numb from top of his cromagnum looking forehead to his toe hairs, that don't mean shit right?" Fucking dumbest argument ever, and proof that you don't know wtf you are talking about. It's not fucking novocaine moron. That's like saying I could smoke a cigarette and then cut off my arm and not feel it...

ok Karma, I was wrong the other night when I said I thought me an armfarmer were bros, my bad.
Hey AF, so glad you could post once every month or so with the most relevant shit on any thread.
Also glad you are Mr. pot know it all, and that you know how every single person reacts to pot. Wow if it wasn't for you who would we have to be a bigmouth douchebag knee jerk reactionary? Oh wait, that's right we still have xeno.
For your OVERbearing goddamn information, pot makes ME numb, thus the term "polio-weed", and MUCH like alcohol you loosen up, and I didn't say it keeps you from feeling things, you just don't GIVE a shit. And If I was high OR drunk I would walk through a ton more kicks and punches, cause I wouldn't give a shit.
So Mr. know it all, non posting, holier than thou asshat, maybe it's YOU who doesn't shit. Now you can get off my ass or you can eat a bag of dicks.
Are we good now...PLAYA?

@darkstarrocketship. diaz is a hero???? maybe to the gangbangers in da 209.....he may care about his principles and the rest be damned yeah agreed....but dont give us that shit about not caring about money,thats all that motherfucker wants, where have you been? that's all he has been complaining about for the last fucking 4 years, and why he keeps implying he's going to go to boxing....As far as weed goes,there is no reason it shouldnt be regulated like tobacco or alcohol.agreed it's ridculous. but the fact remains the NSAC doesnt allow it ,so again it's a moot point no amount of "Fans" complaining about it is going to change that.

darkstarrocketship is my hero,weed, philosophy and starwars...orgasmic
Rejo- February 10, 2012 at 1:32 pm
The problem I have is with the testing method. He could go out and roll a bowl of meth everyday for a month, take 20 pills a day and smoke some crack in between and piss clean in 72 hours, yet fail a test if he smoked a joint once in the last 15-20 days. Just plain stupid. Before anyone comments, I have experienced both of the above situations before, and I can assure you I was in alot worse shape when I passed than when I failed.

Goddamnit Cage Potato! How hard is it to add an edit button? Just how remedial is your web development staff? Are they even literate? Do they even exist? If atomic sub-components are energy then doesn't that mean that there's really only one state of matter since everything is energy and that the whole notion of things being solid is just a useful paradigm that limits our holistic understanding of the universe, it's purpose, our place in it and our purpose?
darkstarrocketship- February 10, 2012 at 12:09 pm
Diaz is a hero. His principles are more important to him than money or accolades. That's what a real man is. It's an alien precept to most of you fags. Whenever I read an anti-weed fag comment it's clear to me that the author is little more than a compliant slave bootlicking the petrochemical industry that sabotaged the recreational smoking of hemp in the first place. Some of you fags are so misinformed, so under-educated and so spiritually nullified, that you'll never understand Diaz for the super-solider and super-mind that he is. I'd feel sorry you if wasn't for the fact that I sadistically take please in the void and great irrelevance that your life is and will conclude as. I'd say go die but I earnestly want you to have to endure the condemned fate that it is to be you, an ignorant fag of the masses completed blindsided to what Diaz represents, a slave a grabs the slave-drivers whip and says no. You fags make physically sick. (preface: contextually, fag does not mean homosexual)

what is this "weed" you speak of?
ArmFarmer- February 10, 2012 at 7:22 am
You guys are right, it's not an issue of the moral/health/ped ramifications of the drug, it's about Diaz breaking the rules. However, when something like this happens the conversation will inevitably go those directions. Please excuse the somewhat off topic debates, but they are always gonna happen.. and it's a pet peeve of mine when people who have no experience or knowledge on something feel the need to weigh in on it with their uninformed bullshit.
