Richardson, an American 'athlete star', who emerged as the best box office card for the Tokyo Olympics, is shocked as he is embroiled in a marijuana scandal.
Richardson emerged as a superstar in the women's 100m sprint due to her distinctive looks and overwhelming skills.
In response, Richardson did not respond, leaving only the vague sentence "I am human" on Twitter.
Disciplinary action related to marijuana, a prohibited substance, is up to four years of suspension.
