I think there should be a definite permanent indicator on a fighters record once testing 'dirty'. Second offense rip their license up. The problem is and I don't pretend to know all the particulars and component and supplement questions..do we even have a 100 percent concise and clear listing of what constitutes illegal substances. 'Banned substance' seems like a bit of a gloss over and feels like fighters have grown to hope for that. Benavides lost more..trinket, time and money for sticking some of that bugger sugar up his nose at a party on his time. Tyson popped and timed out for weed. There needs to be much better definitions and 1 rule applied for all across the board rather than the head of a sanctioning body etc massaging the rules depending on the fame of your name. It's to the point where every camp needs a full time chemist to decipher ingredients as they train.
