Where there's smoke, there's fire -- and there's also Nick Diaz, toking up.

Nevada State Athletic Commission (NSAC) Executive Director Keith Kizer today confirmed that Diaz failed his UFC 143 drug test for "marijuana metabolites" following the "Diaz vs. Condit" pay-per-view (PPV) event last Saturday night (Feb. 4, 2012) in Las Vegas.

Also screened for performance enhancing drugs, as well as drugs of abuse, were Carlos Condit, Fabricio Werdum, Josh Koscheck, Renan Barao, Ed Herman, Dustin Poirier, Max Holloway, Matt Riddle, Henry Martinez, Edwin Figueroa, Alex Caceres, Matt Brown, Chris Cope, Rafael Natal, Michael Kuiper, Stephen Thompson and Dan Stittgen.

Those fighters all passed with flying colors.

For Diaz, this marks the second time he's been popped for marijuana in Nevada, having tested positive following his win over Takanori Gomi back in Feb. 2007.

This result mars an event that was already crawling in controversy, thanks to the controversial main event bout going to a five-round decision finish that few were satisfied with.

In fact, Diaz retired in disgust after the bout, proclaiming his dislike for the scoring system in place in MMA. His team, led by Cesar Gracie, immediately started campaigning for a rematch, so that didn't last long, of course.

He'll now be faced with a mandatory vacation imposed by the NSAC; however, Diaz still has opportunity to appeal the commission's results.

After all the insanity surrounding Diaz since he signed a contract with the UFC, from his removal from the UFC 137 main event for missing press conferences all the way up to this drug test failure, one has to wonder if Diaz is worth the headache he's surely given Dana White.

Then again, UFC 143 drew a better than expected 400,000 buys on pay-per-view.

Either way, stay tuned to as more details are sure to emerge on Diaz's drug test results and pending repercussions in the coming days.
