``This is my medical marijuana license, I don't take other medications, so don't hate,'' tweets UFC welterweight Matt Riddle, who saw his UFC 149 win over Chris Clements go up in smoke after testing positive for marijuana.
Bleacher Report MMA has learned via an emailed press release from the Nevada State Athletic Commission, as well as USA Today.com, that former Strikeforce Welterweight champion Nick Diaz has tested positive for ``Marijuana metabolites'' after a UFC 143 loss to current UFC Interim Welterweight Champion ``The Natural Born Killer'' Carlos Condit.
