UFC star Nate Diaz will not be sanctioned for ingesting a prohibited substance via a vape pen during his UFC 202 post-fight news conference in August. Instead, the U.S. Anti-Doping Agency, which oversees and administers UFC’s strict drug policy, issued a “public warning” to the 31-year-old Thursday.
At the Aug. 20 news conference, the Stockton, Calif., native identified the substance as cannibidiol, a non-psychoactive cannabinoid derived from marijuana that USADA prohibits the use of in-competition only. That’s defined as the window of time that begins six hours before the official weigh-in and ends six hours after the fight. Diaz, who explained the substance “helps with the healing process and inflammation,” claimed that when he ingested it that night, he had thought the in-competition window had ended, USADA explains in the release.
