Professional boxer Kazuto Ioka reprimanded after detection of cannabis ingredients JBC. He was given a reprimand for causing suspicion that the Ioka was found to contain cannabis, a prohibited substance, in a doping test conducted during a super flyweight championship unification match held on New Year's Eve last year.

On the other hand, JBC has determined that there is no violation of the rules as it does not exceed the standards of WADA = World Anti-Doping Agency, and Ioka has continued to compete in world title matches.
