The BBC is reporting that the World Anti-Doping Agency (WADA) is considering banning the use of Viagra at events like the Beijing and London Olympics because it believes sildenafil enhances athletic performance, particularly in high-pollution locations (such as Beijing and London), because it can mimic the effects of the blood boosting agent, EPO (erythropoietin).

I guess, with all that skin-tight running and swimming gear, it will be apparent which male athletes are using Viagra to boost their sporting performance.
