Cynthia Calvillo is the latest fighter to test positive for marijuana metabolites

Last month, Team Alpha Male strawweight contender Cynthia Calvillo experienced her first career loss, losing a close decision to former champion Carla Esparza. Unfortunately, that’s not where the trouble ends for her.

Calvillo has now been notified of a potential UFC anti-doping policy violation after failing an in-competition USADA drug test for the banned substance Carboxy-Tetrahydrocannabinol (THC).

Here’s the UFC’s official statement on this development.

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.

The last fighter to fail a marijuana related drug test was UFC middleweight contender Kelvin Gastelum, who was handed a three-month suspension as a result. His win over Vitor Belfort was also overturned, though the outcome of Calvillo’s bout with Esparza probably won’t change, as she lost the fight.

Prior to her loss to Esparza, Calvillo went 3-0 in the Octagon, defeating Amanda Bobby Cooper, Pearl Gonzalez, and most notably, strawweight veteran Joanne Calderwood.

What punishment do you think is fair in the case of Cynthia Calvillo?
