Sprinter Sha’Carri Richardson suspended one month after marijuana test, putting Olympics in doubt

In WADA’s prohibited list published Jan. 1, the chemical compound found in marijuana, THC, is listed next to cocaine, MDMA/ecstasy and heroin as a substance of abuse. They are considered substances of abuse because they “are frequently abused in society outside of the context of sport,” the WADA rule book reads. The drugs are prohibited in-competition only. Cannabidiol (CBD) is considered an exception, while other cannabinoids are illegal.
