Nick Diaz tests positive for marijuana metabolites after UFC 183

The post-fight drug test continues to be Nick Diaz’s toughest opponent.

Following a unanimous decision loss to Anderson Silva at UFC 183 on Saturday night in Las Vegas, Diaz tested positive for marijuana metabolites, Nevada Athletic Commission (NAC) executive director Bob Bennett confirmed with MMAFighting.com’s Ariel Helwani on Tuesday.

Diaz had more than the allowed maximum of 150 nanograms of the metabolites in his system. He’ll be temporarily suspended and will have to appear before the NAC in order to be relicensed to fight.

This is Diaz’s third time testing positive for weed in his career. He popped for marijuana after a loss to Carlos Condit at UFC 143 and was also suspended in Nevada then. Diaz’s 2007 win over Takanori Gomi was overturned into a no contest and he was suspended again for failing a test for pot.

Silva also failed a drug test, a Jan. 9 out-of-competition screening for drostanolone, an anabolic steroid, and androsterone, a steroid hormone. He, too, is temporarily suspended.

NAC chairman Francisco Aguilar told Helwani that no decision has been made with regards to whether this fight will be overturned into a no contest. That will not get decided until a disciplinary hearing in March or April, the same hearing in which penalties (length of suspension, fines, etc.) will be handed out to Silva and Diaz. The next NAC meeting is Feb. 17, but Diaz and Silva will only be given their temporary suspensions then.

The reason the NAC got back Diaz’s test so quickly is because it was a urinalysis, Aguilar said. The commission still has not received Diaz’s second out-of-competition test. The two men were tested on or around Jan. 9, Jan. 19 and Jan. 31, after the fight. Diaz’s first test came back clean.

All tests were done by the Sports Medicine Research and Testing Laboratory in Utah, Bennett said.
