It looks like Ultimate Fighting Championship and the New Jersey Athletic Control Board have not caught on to the changes in marijuana testing thresholds proposed by the World Anti-Doping Agency. Fighter Pat Healy has been fined, suspended, and his win changed to a "no contest" after testing positive for marijuana after his victory over Jim Miller two weeks ago.
According to UFC president Dana White, his organization will continue to abide by the standards set by various state athletic commissions when it comes to drugs. He does not, however, seem overly concerned with testosterone replacement therapy, which, while legal, can significantly increase the performance of athletes. This means that it is up to state athletic commissions to heed the advice of WADA.
Healy apologized for the incident, saying he made a "very poor choice" and promised to "make a conscious effort to be a better role model within the [mixed martial arts] community."
He shouldn't have to apologize. Not for using a substance that is safer than alcohol and does not overtly enhance performance.
