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.
