For those interested in specific strains mentioned by fighters, such as Suga Show OG or other specialized genetics, Herb’s strain guides provide detailed information about different cannabis varieties and their potential effects.
Yes, effective Dec 31, 2023, the UFC launched a new Anti-Doping Policy administered by Drug Free Sport International where marijuana/THC is no longer prohibited under the UFC program. Under the 2024 UFC policy, THC is not listed as a banned substance, marking a major shift from previous rules that imposed severe penalties for marijuana use. Fighters can now use cannabis products with greatly reduced risk of suspensions under the UFC’s own anti-doping program, although some athletic commissions may still enforce their own THC thresholds and fines. The policy change has enabled many fighters to more openly discuss their cannabis use and launch cannabis-related businesses.
Multiple champions have openly supported cannabis or cannabis products, including Amanda Nunes who has been sponsored by cbdMD. Nate Diaz, while not currently a champion, is perhaps the most vocal advocate and has built successful cannabis businesses including Game Up Nutrition and Kill_4209. Conor McGregor partnered with TIDL Sport, a plant-based recovery brand. Sean O’Malley launched his own ‘Suga Show OG’ strain. The new UFC policy has enabled champions to openly endorse and create cannabis products.
Nate Diaz’s brother Nick received a 5-year suspension (later reduced to 18 months) for a third marijuana offense in 2015. Nate has been more careful about timing his cannabis use to avoid violations under previous policies. He famously vaped CBD at a 2016 press conference, which was legal at the time. Under current UFC policy, neither brother would face penalties for cannabis use. The policy evolution reflects how dramatically the sport’s stance on cannabis has changed.
Yes, WADA removed CBD from its Prohibited List in 2018, and the UFC’s policy change in 2023-2024 means fighters can use all cannabis products without restriction. In a 2020 survey, 76.5% of fighters reported already using CBD products for recovery. CBD has become one of the most widely adopted cannabis-derived products in MMA for pain management, inflammation, and sleep. Fighters can generally use CBD both in and out of competition with fewer anti-doping concerns—though contamination with THC or other banned cannabinoids remains a risk, so product quality and local athletic commission rules still matter. The widespread CBD adoption underscores how commonly athletes now incorporate it into their recovery routines.
While exact numbers for legalization advocacy aren’t available, in a 2020 survey, 45.9% of fighters reported using marijuana for recovery or recreational purposes. Gilbert Urbina estimates that “around 50% of fighters” use cannabis despite lingering stigma. Many of these fighters have become vocal advocates for policy reform and legalization. UFC Senior VP Jeff Novitzky confirmed that marijuana is “probably the No. 1 topic of questions” he receives from fighters. The high usage rates suggest strong support for cannabis normalization throughout the organization.
USADA no longer administers the UFC’s anti-doping program as of Jan 1, 2024. Under the UFC’s new Anti-Doping Policy with Drug Free Sport International, marijuana/THC is not prohibited under the UFC program, so WADA/USADA THC thresholds are no longer used for UFC’s own testing. This marks a major shift from the previous, more restrictive approach. Fighters can now use cannabis without UFC-imposed anti-doping bans on marijuana, though some athletic commissions still enforce their own THC thresholds, fines, or other penalties.
