The International Olympic Committee president Jacques Rogge has hailed a largely drug-free Winter Olympics in Vancouver, with only two minor doping issues at the Games.
Ice hockey players Lubomir Visnovsky of Slovakia and Svetlana Terenteva of Russia were the only athletes found to breech anti-doping rules.
A urine sample from Visnovsky last week found pseudoephedrine in a higher concentration than accepted after he took some cold pills, while Terenteva tested positive for a nasal decongestant drug called tuaminoheptane just before the start of the Games.
Both athletes received reprimands only and escaped bans.
Rogge says it's encouraging that only two minor doping issues had come to light and that at least for traceable products, there has been a deterrent effect.
Salt Lake City in 2002 and Turin in 2006 both saw seven positive tests.
Before the Games the IOC warned that samples taken from athletes would be kept for eight years and could be tested retroactively as new methods to detect unknown products become available.
