Nick Diaz must follow a strict rule in Abu Dhabi after Dana White confirmed his sensational return to the UFC.
Diaz is set to return to the famed Octagon on August 3 when he faces Vicente Luque in a five-round welterweight showdown.
His bout against the No.14 ranked contender will serve as the card's co-main event - under Cory Sandhagen vs. Umar Nurmagomedov.
Other than a few fights in Japan, Diaz has fought his whole pro MMA career in North America.

However, he'll venture to the Middle East for his comeback against Luque.
And whilst out in Abu Dhabi, the 40-year-old must follow a strict rule regarding cannabis.
Diaz, an avid weed smoker, won't be able to smoke marijuana in the country as it's illegal.
It's no secret the UFC legend is a marijuana aficionado. But he will have to abstain from smoking during his visit to Abu Dhabi or risks potential imprisonment.

Diaz's iconic MMA career has spanned over several MMA promotions, including Elite XC and Strikeforce.

And he used to smoke weed with the late Kimbo Slice before Elite XC events back in the day.
"We were always hanging out at backstage at the Strikeforce or Elite XC events and smoke blunts," he revealed when asked what he remembers most about Slice, who passed away back in June 2016.
"We would headline the whole show. It was me and Kimbo Slice."
The former Strikeforce welterweight champion hasn't fought in the UFC since September 2021. At UFC 266, he suffered a defeat to Robbie Lawler.

What's more, the Stockton slugger hasn't won a UFC fight since 2011 when he outpointed fellow great BJ Penn.
Diaz, who has fought the likes of Georges St-Pierre and Anderson Silva, boasts victories over Josh Neer, Evangelista Santos and Paul Daley, among others.
