Nick Diaz is not known for holding his tongue. Just days before he gets a shot at the UFC welterweight champion Georges St-Pierre, Diaz let his true feelings on GSP be known. While on a Toronto radio show, Diaz said he thinks St-Pierre uses steroids.

"I believe that he's on plenty of steroids and I don't believe they've tested him as well," Diaz said. "I don't care what they're saying or marketing to the media. I don't think either of us are going to be tested. ... I doubt they're standing over him, making sure he's not on steroids."

Diaz has tested positive twice for marijuana, which is a banned substance. He is coming off of a suspension for testing positive, and has been warned that he may be released by the UFC if he tests positive again. St-Pierre hasn't tested positive in his career of more than 10 years.

But Diaz is far from the only person who has criticized the UFC's handling of drug tests. Victor Conte, the head of BALCO, has said the UFC doesn't do enough to keep performance-enhancing drugs out of the sport. The head of the United States Anti-Doping Association has also questioned the UFC's drug testing.

Though drug testing and regulation is often handled by the UFC for international fights, this weekend's bouts in Montreal will be regulated by the commission in Quebec.
