Russian figure skater Kamila Valieva has been cleared to compete in the 2022 Winter Olympics despite being the subject of an ongoing banned substance investigation. Now, U.S. track star Sha'Carri Richardson wants to know why she was banned from competing in the Summer Olympics for a similar situation.

Richardson was barred from competing in the 2020 Tokyo Summer Olympics for 30 days after testing positive for marijuana, sparking an overall conversation on the way the drug should be viewed by the World Anti-Doping Agency in the future, as Blavity previously reported. At the time, Richardson said she decided to smoke marijuana as a coping mechanism while grieving the recent death of her mother.

“Can we get a solid answer on the difference of her situation and mines? My mother died and I can’t run and was also favored to place top 3,” Richardson tweeted Monday, accusing the International Olympic Committee of showing a racial bias. “The only difference I see is I’m a black young lady.”

"It’s all in the skin," she continued, adding, "Btw THC definitely is not a performance enhance!!!!"

According to Reuters, the World Anti-Doping Agency, the International Olympic Committee and the International Skating Union are prepping for an intense investigation into 15-year-old Valieva's case. The Russian skater provided a sample on Dec. 25 that tested positive for a banned substance, trimetazidine. However, the Court of Arbitration for Sport (CAS) cleared Valieva to compete despite the controversy, upholding a previous ruling by the Russian Anti-Doping Agency (RUSADA) to lift the provisional ban.

While she's able to still participate in Beijing, Valieva won't be allowed to take home any medals should she place in either the team or individual women's events — until, at the very least, the case has been resolved, The New York Times reports.

RUSADA still has to close its case against Valieva first before it's expected to possibly go through the World Anti-Doping Agency and CAS again.

The nuance of Valieva's story doesn't seem lost on Richardson. Though, it's not enough to convince her that her experience was anything but racially motivated.

"Failed in December and the world just now know however my resulted was posted within a week and my name & talent was slaughtered to the people," Richardson went on.

"Not one BLACK athlete has been about to compete with a case going on, I don’t care what they say!!!" she tweeted.
