World Anti-Doping Agency to review cannabis ban in wake of Sha'Carri Richardson controversy

The World Anti-Doping Agency (WADA) executive committee announced on Tuesday it will review cannabis' status as a banned substance. The announcement came two months after U.S. sprinting star Sha'Carri Richardson was disqualified from the Tokyo Olympics for using marijuana after she had learned that her mother died. 

WADA said in a statement that the review was prompted after the agency received requests from "a number of stakeholders." The scientific review of cannabis will be initiated in 2022, the agency said, and will be conducted by the agency's Prohibited List Expert Advisory Group. 

Until any change of its status is confirmed, cannabis will continue to be prohibited in competition through at least 2022.
