UFC women’s strawweight contender Cynthia Calvillo is the latest fighter to fail a drug test for marijuana metabolites.
Cynthia Calvillo may be facing sanctions to go along with her first professional loss in MMA.
Calvillo has been informed of a potential UFC anti-doping policy violation, the UFC announced in a statement Wednesday evening. She tested positive for Carboxy-Tetrahydrocannabinol (Carboxy-THC) — over the limit of 180 ng/mL — in an in-competition drug test administered by the U.S. Anti-Doping Agency (USADA). The test was in relation to her unanimous-decision loss to former champion Carla Esparza at UFC 219, which took place Dec. 30 in Las Vegas.
Carboxy-THC is a “metabolite of marijuana and/or hashish,” per the statement.
The Nevada Athletic Commission (NAC) oversaw UFC 219, headlined by Cris Cyborg vs. Holly Holm, and has jurisdiction over Calvillo. Therefore, the women’s strawweight contender faces a sanction from the regulatory body, too.
“USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case involving Calvillo, as it relates to the UFC Anti-Doping Policy and future UFC participation,” the statement read.
Calvillo, who debuted in the promotion in early 2017, is 3-1 in the UFC.
