Sha’Carri Richardson, the U.S. sprinter who qualified for the Tokyo Games last month, has been suspended from the Olympic team after testing positive for THC, the chemical in marijuana, her lawyer said.
A U.S. Olympic source told NBC News that Richardson failed a drug test following her win in the 100-meter race on June 19.
She is now prohibited from competing in that race, but could possibly compete in another event.
It is unclear if she will appeal the drug test results.
Richardson on Thursday tweeted, “I am human.”
She ran the 100 meters in 10.86 seconds, catching the attention of fans around the world. During a post-race interview with NBC, Richardson revealed that her biological mother had died the week before.
