The Nevada State Athletic Commission on Tuesday changed the result of Nick Diaz's gogoplata victory over Takanori Gomi to a no-decision after it deemed that the use of marijuana aided in the Californian's Feb. 24 win over the PRIDE champion, NSAC executive director Keith Kizer confirmed to Sherdog.com.

Diaz's license was suspended six months, retroactive to the date of the fight, and he was fined $3,000, a sum equivalent to 20 percent of his purse.

According to MMAweekly.com, NSAC commission chairman Dr. Tony Alamo stated during Tuesday's hearing in Las Vegas that Diaz's Delta-9-THC (the active ingredient in marijuana) reading was an off-the-charts 175. A test is considered positive when THC levels broach 15, while Nevada holds its standard at 50.

"This creates a unique situation," expressed Alamo.

"I was there at this fight and believe that you were intoxicated, and that it made you numb to the pain," Alamo told Diaz, who was present. "Did it help you win? I think it did."

"I wasn't under the influence when I was fighting," Diaz responded. "I don't abuse drugs normally; it was a one-time thing. It was very embarrassing for me to test positive."

During an interview on the Sherdog Radio Network's "Beatdown," Diaz's manager Cesar Gracie questioned the NSAC's decision to change the fight result when it has not done so in previous "performance enhancement" related suspensions.

"Tim Sylvia kept his win when he tested positive for steroids, and because Nick tested positive for pot they're going to take his victory away, fine him $3,000 and suspend him for half of the year?" said Gracie. "I mean I think they just shot themselves in the foot. They didn't shoot Nick in the foot. They look like idiots out there."

In fact the NSAC has changed a result once before, after it amended regulation in December 2005 to allow for such a ruling. Following a positive test for methamphetamine stemming from a Nov. 2006 fight, boxer Omar Nino's majority draw with Brian Viloria was changed to a no-decision, Kizer said.

"Gomi is a great opponent, he's really tough," said Gracie. "You don't want to go in there high against a guy. You can't think, focus and react quickly. Obviously Nick won the fight. They were saying,
