Fan-favourite Nate Diaz returns to the UFC this weekend to face off against Britain’s Leon Edwards.

The Stockton native’s no-nonsense personality, and willingness to fight anyone, anytime, has endeared him to countless fans over the years.

At the UFC 263 press conference, Diaz joined the likes of Israel Adesanya and Marvin Vettori to answer media questions.

During the presser, Diaz could be seen appearing to take a puff of a joint.

He then reportedly asked UFC flyweight contender Brandon Moreno if he wanted a hit of Kill_4209.

What was Nate Diaz smoking?

Fans speculated that Diaz wasn’t actually smoking weed, and that it was CBD instead.

However, according to ESPN’s Brett Okamato, Diaz was smoking marijuana, and in fact, it was his own brand, Kill4209.

Okamato confirmed that rules in Arizona – where the fight is taking place – allows Diaz to smoke closer up to the fight than other states.

On Friday, UFC VP of Athlete Health and Performance Jeff Novitzky confirmed the updated rules around marijuana use.

“Great working with AZ Commission, who are adopting our testing program/rules for this weekend,” Novitzky tweeted ahead of UFC 263 in Arizona.

“Only issue with marijuana (THC) for Saturday’s fights is don’t show up impaired or under the influence. How it should be!”
