How Pervasive is Doping in Elite Mixed Martial Arts?

Elite level MMA has been under the microscope recently with unwanted drug scandals.  From Light Heavyweight Champion Jon Jones pre UFC 182 cocaine use to former Middleweight Champion Anderson Silva’s reported anabolic steroid use prior to UFC 183 the sport has received more than its fair share of negative spotlight in recent weeks.

If elite MMA wishes not to be relegated to the fringes of the sporting world doping needs to be cleaned up.  With MMAJunkie.com reporting that an astonishing 31% of known out of competition tests result in positive drug findings the problem appears pervasive.  Although the sport had its roots in self regulated uncharted waters and overseas policies which arguably outright encouraged steroid use (as can be seen from the below clause from a Pride FC Fighter Contract), modern acceptance and continued growth of the sport requires a comprehensive answer to its doping problem.

So how many Performance Enhancing Drug busts have occurred in elite MMA?  A member of MixedMartialArts.com’s ‘the underground’ forum has compiled the below sobering list.  Doping can be weeded out with effort from Athletic Commissions and financing from elite promotions.  A top down answer is needed and hopefully the sports regulators can stop the below list in its tracks before it continues to grow for the safety of future competitors and for the sake of the sensible growth of the sport –
