Nick Diaz says brother Nate was smoking marijuana at UFC 202 post-fight presser

Ultimate Fighting Championship (UFC) superstar Nate Diaz found himself in trouble earlier this year when he was seen using a vape pen shortly after his five-round loss to current lightweight champion Conor McGregor at the UFC 202 event on 20 August.

The American fighter had refuted suggestions he was using marijuana, claiming that he was puffing on CBD, which helps in the healing process and inflammation especially after fights and bouts. Cannabidiol is one of 13 active cannabionids present in cannabis and are banned in-competition by the World Anti-Doping Agency (Wada) code over certain usage, with in-competition considered to be six hours before and six hours after a fight.

"It's CBD. It helps with the healing process and inflammation, stuff like that. So you want to get these for before or after the fights, training. It will make your life a better place", Diaz said at the post-fight press conference.

However, now Nate's brother Nick Diaz said that he was smoking marijuana and not CBD as claimed earlier. The 33-year-old also believes that marijuana is a performance enhancing drug, comparing it to vitamins.

"That wasn't CBD. He (Nate Diaz) was smoking the chronic. That was some kush. I do think it's a performance enhancing drug, but I mean like, so are vitamins. People get really misconstrued on that whole thing. I'd like to start shedding some light on this stigma that people that smoke weed are lazy or that they're not thinkers or something", Nick said, as quoted by MMAMania.

"It's really limiting to die without ever smoking weed or indulging in some way because my grandfather did and I don't think he ever did. The thing is, once you've actually gone down that road, then you've subjected yourself to the other side of things and you've gotta start to see perspectives and just not limiting yourself to understanding those perspectives is a really big thing to me. Limiting yourself, in general, is a really big thing to me. Becoming conditioned and limiting yourself, it screws with me.

Nick has been in the news for marijuana use in the past, with the welterweight fighter having three offences against him in the state of Nevada. He recently completed an 18-month suspension for a third marijuana-related offence.
