Jamaican sprinter 23-year-old Shelly-Ann Fraser has tested positive for a prohibited substance Oxycodone at the Diamond League in Shanghai meeting on May 23, 2010.
Shelly Ann Fraser reportedly had taken the narcotic given to her by her coach, Stephen Francis to offset the pain from three tooth fillings she had performed prior to the Shanghai meeting. Oxycodone is listed as a banned substance by the World Anti-Doping Agency, but is not known to have any performance-enhancing qualities.
