An advisory group to the World Anti-Doping Agency (WADA) will review whether cannabis should remain a banned substance, a move that comes after American athletics star Sha'Carri Richardson missed the Tokyo Games after testing positive for it.
The scientific review will be initiated next year, WADA said on Tuesday. Cannabis will continue to be banned in 2022, it added.
Richardson tested positive for a chemical found in cannabis during the U.S. Olympic Track & Field trials in June, which wiped out her trial results. She was also hit with a one-month suspension.
The 21-year-old, who had been seen as a top contender in the 100 metres, has said she used cannabis to help cope with the death of her mother.
The suspension sparked an outpouring of sympathy and calls for a review of anti-doping rules, including by the U.S. Anti-Doping Agency.
