Cynthia Calvillo’s first career loss just got a little bit worse.
Three weeks after dropping to 6-1 as a pro with a unanimous decision loss to Carla Esparza at UFC 219, the promotion announced Wednesday that the 30-year-old Calvillo has been notified of a potential UFC anti-doping policy violation after failing a USADA drug test for Carboxy-Tetrahydrocannabinol (THC). The positive test stems from an in-competition sample collected in relation to the Dec. 30 bout, which took place in Las Vegas, Nev.
Carboxy-THC is described in the release as “a metabolite of marijuana and/or hashish.”
Calvillo is expected to go through am adjudication process with USADA and the Nevada Athletic Commission (NAC), which also has jurisdiction in the case, to determine what sanctions she will receive.
The most recent case of a UFC fighter failing a marijuana test involved middleweight contender Kelvin Gastelum. He was flagged by USADA last April, which led to a win over Vitor Belfort being overturned to a no contest, a subsequent booking against Anderson Silva at UFC 212 being canceled, and a three-month suspension.
The UFC’s statement can be read below.
The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA) informed Cynthia Calvillo of a potential Anti-Doping Policy violation involving Carboxy-Tetrahydrocannabinol (“Carboxy-THC”) which is a metabolite of marijuana and/or hashish, above the decision limit of 180 ng/mL, stemming from an in-competition sample collected in conjunction with her recent bout in Las Vegas, Nevada on December 30, 2017, UFC 219: Cyborg vs. Holm.
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. Because the Nevada Athletic Commission was the regulatory body overseeing the fight in Las Vegas and has licensing jurisdiction over Calvillo, USADA will work to ensure that the Nevada Athletic Commission has the necessary information to determine its proper judgment of Calvillo’s potential anti-doping violation. Additional information will be provided at the appropriate time as the process moves forward.
