• Sha'Carri Richardson officially banned for one month for marijuana and will miss Tokyo Olympics
The U.S. 100m champion Sha'Carri Richardson will miss Tokyo Olympic Games after she tested positive for marijuana.
The 21-year-old was given one month ban from sports after she tested positive for Cannabis (marijuana) at the U.S. Olympic trials in Eugene meaning she will not be able to compete in Tokyo.
Cannabinoids including marijuana and THC are banned in competition and are categorized as Specified Substances by the WADA Code.
"Don't judge me, because I am human, I just happen to run a little faster," Richardson told NBC's Today show on Friday.
"The rules are clear, but this is heartbreaking on many levels," said USADA chief executive Travis Tygart.
"Hopefully, her acceptance of responsibility and apology will be an important example to us all that we can successfully overcome our regrettable decisions, despite the costly consequences of this one to her."
Richardson holds the second-fastest 100m time of 9.72 seconds in the world this year. She was one of the favorites to win the gold medal at the Tokyo Olympics.
