Train hard: WADA worried about Viagra doping threat

MONTREAL: World Anti-Doping Agency boss John Fahey acknowledged that Viagra is being examined for its potential use as a performance-enhancing drug.

WADA is currently sponsoring a study to determine whether the blue, diamond-shaped pill, widely associated with treating sexual dysfunction in men, may be used for a competitive advantage in sports, according to the New York Times.

"It's amazing the interest that particular drug does attract," WADA president Fahey said Sunday following a board meeting. "I can simply say this, there have been statements to suggest that it is performance-enhancing - that is being evaluated."
