Olympic sprinter Sha’Carri Richardson’s hopes of winning an Olympic gold medal in the 100 meters this summer are gone after she tested positive for marijuana.

Richardson is facing a 30-day suspension for her positive test. She will not compete in the 100 in Tokyo, which is scheduled for July 31. There was some hope that Richardson might be able to compete in the 4×100 relay, which is set for Aug. 6, as her suspension will be up by then.

However, her positive test disqualified her winning time in the U.S. trials, so she will not participate in the 100.

After the reports of Richardson’s suspension went online, many commenters began wondering why Michael Phelps was able to compete in the Olympics after a photo of him smoking weed from a bong, which he confirmed was authentic, leaked in 2009.
