The following is an excerpt from an article on MMAWeekly.com:
Fighter Nick Diaz, following his defeat of Takanori Gomi on the February 24, 2007 Pride event in Las Vegas, Nevada, also tested positive for Delta-9-THC. The commission suspended Diaz for 6 months from the date of his fight, which would be August 24, 2007 and fined him $3,000, which was 20 percent of his reported $15,000 purse.
Though Diaz' disciplinary suspension will last six months, Diaz was already serving a six-month NSAC medical suspension due to a broken orbital bone suffered in the Gomi fight.
In addition to the suspension and fine, the NSAC also ruled that the result of the Diaz vs. Gomi contest be changed from a victory for Diaz to a result of no contest.
Apparently, the commission felt that the level for which Diaz tested at, 175, was a considering factor in his performance during the fight. Dr. Tony Alamo, the Commission's Chair, said that a result of 15 is considered positive, but that the NSAC has a threshold of 50 to test positive for THC and that they “feel very comfortable that everyone that tests positive [in Nevada] is truly positive.”
Alamo went on to say, “Mr. Diaz was 175. This creates a unique situation. I was there at this fight and believe that you were intoxicated and… that it made you numb to the pain. Did it help you win? I think it did.”
In his statements to the commission, Diaz said, “I wasn't under the influence when I was fighting. I don't abuse drugs normally; it was a one-time thing. It was very embarrassing for me to test positive.”
