The Canadian Olympic Committee announced today that no Canadian athletes have violated Olympic anti-doping rules. However, the World Anti-Doping Agency says 30 other athletes have been banned from the Vancouver Olympics for failing drug tests. “We’re getting better. Anti-doping agencies are getting better. The weaponry that’s being used is far more effective,” says John Fahey, president of the WADA. “It’s more likely they will be caught than at any other Games in our history.” A further 2,500 tests are expected to be administered at the games, far more than at the last winter Olympics in Turin.
