Fear And Loathing In Las Vegas: A Comprehensive List Of MMA Drug Busts


UFC Poland: Mirko Cro Cop excited to finally get "important ...

Maybe this article sounds cynical? Well, let’s take a look at some of the drug busts/testosterone busts in MMA since the turn of the millennium: Josh Barnett x2, Chael Sonnen x3, Wanderlei Silva, Alistair Overeem, Sean Sherk, Tim Sylvia, Royce Gracie, Vitor Belfort x2, Nate Marquardt, Cung Le (later vindicated due to bungled testing), Ali Bagautinov, Ken Shamrock (obviously), Dennis Siver, Josh Burkman, Kevin Randleman, Piotr Hallman, Brian Ortega, Mike King, Kevin Casey, Robert Drysdale, Thiago Tavares, Joey Beltran, Stephan Bonnar x2, Feijao Cavalcante, Muhammad “King Mo” Lawal, Cris “Cyborg” Santos (now Justino), Pat Healy, Dave Herman, Matt Riddle, Rob Emerson, Thiago Silva, Thiago Tavares, Chris Leben, Dennis Hallman, Carina Damm, Hermes Franca, Phil Baroni, Antonio “Bigfoot” Silva x2, Kimo Leopoldo x2, Ricco Rodriguez, Rousimar Palhares, Lavar Johnson, Brian Bowles, Ben Rothwell, Doug Marshall, Mike Richman, Gilbert Melendez, Ashlee Evans-Smith, Alexander Shlemenko, ‘The Bellator 4’: Rob Emerson, Nick Moghaddam, Fernando Gonzalez and Keith Berry, Augusto Montano, Jessica Eye, Jake Shields, Joe Warren, Nick Diaz for weed x3, Jon Jones for cocaine, Jon Fitch, Hector Lombard for a designer steroid and Anderson Silva for two types of steroids and Mirko Cro Cop for human growth hormone. And breathe….

This list will be constantly updated as more fighters fail drug tests.

And even with the more stringent and regular/random testing, we are seeing guys still using. Who would’ve thought that in the space of just one month and seven days, we’d see two of the UFC’s marquee fighters shamed for failed drug tests. So where does this whole thing go from here? If you ask me, it’s only going to get worse.

The very nature of the sport breeds a ‘never say die’ attitude, one that in turn means athletes will do anything to relive their glory days, or to maintain a level of performance that otherwise may not be attainable. There is light at the end of the tunnel, but I feel that there are many high profile drug busts to come before that time.

Strap yourself in, because 2015 continues to bring out shock drug test results, and we’re probably in for a lot more.

Let us know if we missed any names and they’ll promptly be added to the list!
