Update (July 6, 2021): After being suspended from the Olympic team and losing her chance to compete in the 100m in Tokyo, Sha'Carri Richardson will now miss out on the Olympics after not being selected for the relay event. 

The New York Times reported on Tuesday that Richardson was not selected by American track officials for the 4x100m relay event. Richardson admitted to using marijuana prior to the Olympic trials last month after learning about the death of her mom by a reporter, as Blavity previously reported. 

According to The New York Times, Richardson who is the fastest American woman, was suspended for 30 days after she tested positive for the drug, eliminating her chances of competing in her main event.

Although athletes must finish trials in the top three, track officials are able to select at least two additional runners regardless of their performance. If selected, Richardson would have been able to compete in the relays which take place after her suspension. 

Track officials, however, had already selected and notified the additional runners for the Olympic team at the time the results of her drug test were announced.

Richardson says she will now focus on competitions after the Olympics.

Seemingly aware of the support she has since received, Richardson posted on Twitter, thanking her community.

"The support. My Community I thank y'all, the negative forget y'all and enjoy the games because we all know it won't be the same," she wrote.

She also later tweeted, promising to be the next world champion.

"I'm sorry I can't be y'all Olympic Champ this year but I promise I'll be your World Champ next year," she said. 

Original (July 2, 2021): After winning the 100-meter trials in grand fashion in Eugene, Oregon, Sha’ Carri Richardson will not be able to participate in the event at the Tokyo Olympics after she tested positive for marijuana, CBS Sports reported.

Richardson failed the drug test after her victory in the women's 100m at the U.S. Olympic track and field trials, a source told NBC.

On Thursday, Richardson tweeted, "I am human."

"I want to take responsibility for my actions," she said in an interview Friday on NBC  Today. "I know what I did. I know what I'm supposed to do, (what) I'm allowed not to do and I still made that decision."

"Don't judge me because I am human," she added.

Richardson added that she wasn't excusing her actions and alluded to the loss of her mother as life-changing.

"Finding out something like that, something that I would say is probably one of the biggest things that impacted me positively and negatively in my life when it comes to dealing with the relationship with my mother," she said while discussing the challenges of coping. 

It was revealed during the interview on Friday that Richardson learned about the passing of her mom through a reporter just days before the trial. 

"I still have to go and put on a performance for my dream. Go out there and still compete. So yes it is triggering," she said. "Blinded by emotions. Blinded by sadness. Blinded by just hurting. Hiding hurt."

The use of marijuana is legal in the state of Oregon. 

The 21-year- sprinter from Dallas, Texas posted the sixth-fastest time in the history of the 100-meter, setting a personal best of 10.72 last April. 

Andre Lowe of Jamaica Gleaner reported, "traces of the substance" were found in Richardson's sample collected at the Olympic Trials.

As Blavity previously reported, Richardson wowed the audience with her speed and style at the Olympic trials. She ran the 100 meters in 10.86 seconds, which was one of her five runs under 11 seconds this season.

With her performance, she was one of the favorites to win the gold medal in the women's 100. Also, she gained attention when she ran into the stands following the race and embraced her grandmother, Betty Harp, while sharing the loss of her biological mother.

With her Olympic dreams now in question, Richardson plans to focus on herself.

"Right now I’m just putting all of my energy into dealing with what I need to deal with to heal myself,” she added.

It is unclear if Richardson will appeal the test result and the disqualification.
