Only weeks before the Tokyo Olympics, US sprinter and athlete has received a one-month suspension after she tested positive for marijuana. Sha'Carri Richardson is suspended for a month after testing positive for marijuana in Oregon, where it is legal. She cannot run the Olympic 100m race but may do relays. She told NBC she used marijuana, banned by anti-doping agencies, to cope after her biological mother's death. pic.twitter.com/YcPpUlWeOW — AJ+ ...
