Back in January the UFC and USADA made a joint announcement on the future of the promotion’s drug testing protocols. Namely, they effectively scrapped any and all testing for THC metabolites (barring signs of clear and obvious physical impairment on fight night), the principal psychoactive ingredient in marijuana.
That didn’t mean that fighters were entirely clear of any potential punishment for toking up in the days and weeks before fight night, however. They still had to contend with state athletic commissions, who each have their own set of standards as to what will and will not be tested for in the days surrounding competition.
