WADA chief: Cheats should withdraw before Olympics

The head of the World Anti-Doping Agency has a message for drug cheats: Withdraw from your Olympic teams and stay away from the London Games.

WADA President John Fahey says athletes will face the most severe anti-doping program in Olympic history and stand only a small chance of escaping detection.

With less than three weeks until the opening ceremony, Fahey says "if you are a doping athlete and you are planning to compete in London then you must withdraw from your Olympic team."

He urged athletes to "collectively take more responsibility for the sake of clean competition."
