In seriousness, I think Althugz is bang on here. I'd even go as far as to say fighters should be able to put it into the contracts that they can use whatever they please and just say to hell with the comissions. It's essentially safer than what occurs anyways; if two fighters agree to face each other knowing damn well they won't get caught for using something, where is the incentive to be clean? The idea of one person not using drugs in preparing to fight someone who clearly is but won't have to answer for it is ridiculous.
As paying customers we are now entitled to see the best athletes which science can produce! Viva la revolution!!!
