During the interview, the sprinter told Savannah Guthrie that she was aware of her decision to use marijuana.

“I know what I’m supposed to do. … I still made that decision,” she said at the time.

She explained that her biological mother had died the week before and that she used marijuana after being “blinded by emotion, blinded by bad news, blinded by just hurting, hiding hurt honestly. … I was just trying to hide my pain.”

Richardson tested positive for marijuana in Oregon, a state where the recreational use of the substance is legal. However, the World Anti-Doping Agency (WADA) and USA Track and Field banned the use of the substance.
