The World Anti-Doping Agency will investigate Commonwealth Games 100-meter champion Kim Collins of St. Kitts. He was allowed to keep his medal despite testing positive for a banned substance used in medication.
WADA's chairman Dick Pound has also asked Australian officials to explain why shooter Philip Adams was allowed to compete, despite testing positive for a banned substance that was also in prescribed medication. Collins tested positive for salbutamol, used in the treatment of asthma.
WADA officials were observing drug testing procedures at the Commonwealth Games, but have no jurisdiction.
The only competitor kicked out of the Games so far has been Canadian triathlete Kelly Guest, who tested positive in the pre-Games test for nandrolone. Canadian rugby player Fred Asselin was waiting to learn if he could compete in the rugby sevens tournament after testing positive to a banned subtsnacxe contained in medication he used for a toothache.
