FILE - In this June 19, 2021, photo, Sha'Carri Richardson celebrates after winning the first heat of the semis finals in women's 100-meter run at the U.S. Olympic Track and Field Trials in Eugene, Ore. From doping, to demonstrations to dirty officials, the Olympics have never lacked their share of off-the-field scandals and controversies that keep the Games in the headlines long after the torch goes out. Only weeks before the start of the Olympics, the ban of American sprinter Richardson for a positive marijuana test fueled a debate about whether that drug — not considered a performance enhancer and now legal in some parts of the globe — should be forbidden anymore.
