A third alleged failed drug test for Nick Diaz was greeted by many in the MMA community with a shrug of the shoulders. As it turns out, though, there is more to the story surrounding his positive test.

The onetime welterweight title challenger and UFC veteran was drug tested three times on the night he fought ex-middleweight champ Anderson Silva at UFC 183. He failed one test for marijuana metabolites, prompting the overseeing Nevada State Athletic Commission to file a complaint in what was his third alleged rule infraction for the drug. A hearing on the matter is pending.

But Diaz, 31, also passed two of the tests administered on Jan. 31, both of which were conducted by the Sports Medicine Research and Testing Laboratory, a WADA-accredited facility in Salt Lake City.
Diaz’s testing documentation in connection with UFC 183, which took place at Las Vegas’ MGM Grand Garden Arena, as well as the NSAC’s complaint and a response by his legal team, were provided by the commission after a public records request by MMAjunkie.

NSAC Executive Director Bob Bennett did not immediately respond to a question requesting clarification on why Diaz was tested three times on fight night, though the fighter was suspended and fined for marijuana by the commission in 2007 and 2012.
According to his UFC 183 testing documents, Diaz was twice tested out-of-competition by the NSAC with the results interpreted by the SMRTL. The WADA lab screeed his urine using a “WADA partial menu” for specific performance-enhancers and his blood for human growth-hormone in addition to a “blood passport” examination.



On fight night, however, Diaz’s urine was taken three times and sent to two different laboratories – SMRTL and Quest Diagnostics, the latter of which the NSAC uses to conduct tests for drugs of abuse such as marijuana.

Diaz first gave his urine at 7:12 p.m. – before his UFC 183 headliner – to a collector working on behalf of the SMRTL. The test came back negative when run through a “WADA full menu,” which includes drugs of abuse.
At 10:38 p.m., after his fight, he gave his urine to another collector working on behalf of Quest. The sample ultimately came back showing marijuana metabolites in excess of 300 ng/mL, or double the NSAC’s allowed amount of 150 ng/mL.

Then, at 11:55 p.m., Diaz gave his urine to the same collector for SMRTL. He again passed the WADA full menu.
In its complaint against Diaz, the NSAC cites the Quest Diagnostics findings as the basis for its complaint, also noting the fighter’s failure to disclose his use of marijuana on pre-fight medical paperwork. The test documents from Quest are included as exhibits to the complaint. The SMRTL test results are not.

In a response dated April 9, Diaz, via his legal rep, denied the NSAC’s allegations but did not provide any counterarguments, presumably reserving them for the fighter’s hearing, which is expected to take place in May.
Diaz (26-10 MMA, 7-7 UFC) lost via unanimous decision to Silva (34-6 MMA, 17-2 UFC) in the UFC 183 headliner in his first fight since retiring after a 2012 loss to now-former champ Georges St-Pierre. The loss, however, could be overturned with Silva’s positive test for multiple banned substances. Silva is also expected to appear before the commission in May.

this is not possible considering the short time frame.

When you exercise or do something physically strenuous your body burns fat which is where thc is stored. Could that be why he failed the test immediately after? Also I have a bachelor's in bro science from University of Phoenix, so take that as you may. (cost me 60k)

there are several scenarios sort of like this that are possible. But they all are much less likely then differences between quest and SMRTL lab. I wouldn't be as concerned about a false positive on a quantitative test that quest performed as I would be knowing more about the SMRTL lab techniques. in general, I would expect that the quest test was accurate at least in a qualitative sense. They may be inaccurate in regards to the quantitative value given.

I'm sure nick smoked based on these tests. Tests will always have a false negative and positive. I would like to know if SMRTL reported NEGATIVE due to some threshold or if they reported a value of 0 ng/ml. If they both reported zero then we have a very strange situation. IG they both essentially said <150ng/ml then things are easy. Nick was too close to the line and either dehydration or some other metabolic process left him elevated. Or the lab sensitivities are slightly different.

I've got another suggestion. Nick should just not smoke during the 2 weeks before a fight instead of gambling statistics that will always exist no matter who does the lab.

Passed at 7:12 p.m.

Failed at 10:38 p.m.

Passed at 11:55 p.m.

Splinty - Are you saying it's possible the tests provided false negatives? Or Nick smoked weed after 7:12pm, and the metabolites were out his system by 11:55pm? That seems impossible to me.

You're missing critical details...

Passed at 7:12 p.m. SMRTL

Failed at 10:38 p.m. QUEST

Passed at 11:55 p.m. SMRTL

what is the testing protocols SMRTL performed? Was the result ZERO or NEGATIVE?

Nothing about nick smoking.
Focus on differences in labs. Was SMRTL looking for a QUALITATIVE or QUANTITATIVE result?

without several details it's unclear why the difference.

Nick had some weed in him I'm sure of it from the quest results. The question to me is way more about what level he had and what SMRTL was looking for as a cut off.

should be the highest standard in the testing field.

That's a huge assumption.
Were they running a yes/no test or were they running a quantitative test? Lots of information missing here.

Quest? Fucking did my drug testing there.. its off industrial.. fuck that place for fights.
Its a national level company.

Well I'm not focusing on why they did so many in the first place. Just that the information given isnt clear that there was any mistake.

i wanna bet the WADA lab runs a measured test and not a on or off test.
and since these records are made to be public i expect a decent journalist will get these three test by a freedom of info act, just like they did with Jones his test.

Let the man smoke. I believe had has a prescription in California doesn't he? I know the NSAC doesn't care about that, but I think they should. Seems pretty clear to me that he has some anxiety issues. I wish they would legalize it here so I could blaze it up!

Is weed that important? It seems idiotic that a professional can't cut it out during camp. You're going to give up all that money just to toke up? It's against the rules. Who cares if it's a stupid rule as long as you're getting paid?

It's a only against the rules immediately before/after and during the event.
