You may have heard the news this week about American track-and-field athlete Sha'Carri Richardson. The U.S. Anti-Doping Agency announced yesterday that Richardson had accepted a one-month suspension from competition after testing positive for marijuana at the U.S. track and field trials last month. The suspension means Richardson may not be able to represent the U.S. at the upcoming Tokyo Olympics, despite her dominating the 100-meter race at trials and earning a spot on Team USA with that performance. She had been considered a favorite for a gold medal in Tokyo in the 100 meters. Now, it's not clear if she'll even take part in the games at all.
