Nate Diaz went to war with Conor McGregor at UFC 202 over the weekend, and after five rounds of glorious combat where he left most of his body and soul in the Octagon, he went back stage, pissed in a cup, got checked out by a doctor, and took a shower. Then it was time for the post-fight presser, so Diaz sat before the assembled reporters, answering questions with a vape pen in hand.

And now those motherf*ckers at the USADA are on him about that vape pen.

As per MMAFighting:

Diaz might be facing a UFC anti-doping policy potential violation for vaping cannabis at the UFC post-fight press conference Saturday night in Las Vegas, MMA Fighting has learned. Diaz was vaping on the dais and, when asked, said it was CBD, or cannibidiol oil.

“It’s CBD,” Diaz said after his majority decision loss to Conor McGregor. “It helps with the healing process and inflammation, stuff like that. So you want to get these for before and after the fights, training. It’ll make your life a better place.”

Cannibidiol is one of 113 active cannabinoids in cannabis. Cannabinoids are banned in-competition by the World Anti-Doping Agency (WADA) Code over a certain threshold and USADA uses WADA’s prohibited substance list. In competition is considered the six hours before and the six hours after a fight. Diaz’s appearance doing post-fight media was within that timeframe.

“I can confirm that USADA is aware of the situation and is currently gathering information in order to determine the next appropriate steps,” USADA spokesperson Ryan Madden told MMA Fighting in a statement.

Leave Diaz alone!

But really, it doesn’t matter if he gets suspended for a year. Homeboy is now a millionaire. He’s earned some time to chill.
