The American sprinter Sha’Carri Richardson, who was set for a star turn at the Tokyo Olympics this month, tested positive for marijuana at the U.S. track and field Olympic trials, according to two people with knowledge of the test results who requested anonymity because they were not authorized to discuss the situation.
Richardson, 21, won the women’s 100-meter race at the U.S. trials in Oregon last month, but her positive test automatically disqualified her from that marquee Olympic event. It is unclear whether she will appeal the test result and the disqualification.
U.S.A. Track & Field has notified other women who competed in the 100-meter final about the failed drug test, according to one person with direct knowledge of that information, and several have been told that they have moved up a spot in the final standings.
