More than a half million fans are coming to the defense of America’s fastest woman, flamboyant track star Sha’Carri Richardson, who has been barred from Olympic competition over marijuana use after winning the 100-meter dash with a time of 10.86 seconds during the U.S. Olympic trials in Eugene, Ore., on June 19.

Richardson, who became a fan favorite with her long orange hair, long lashes, long painted fingernails and lightning speed, was given a one-month ban on July 1 after testing positive for THC, the active component of marijuana.

Marijuana is legal for adult use in Oregon, but it is banned by the International Olympic Committee’s World Anti-Doping Agency unless an athlete has been granted a medical exemption.

Richardson’s 30-day suspension disqualified her from the 100-meter dash at the Tokyo Olympic Games later this month, but officials had left open the possibility that she would be allowed to run in the women’s 4x100 relay that starts Aug. 5.

But her name was missing Tuesday from the 130-person roster sent out by USA Track & Field. The federation had two discretionary picks beyond the top four finishers in the 100-meter final at trials but chose not to offer a spot to the 21-year-old sprinter, who was expected to challenge for Olympic gold.

Asked how Richardson was taking the news, her agent, Renaldo Nehemiah, responded late Tuesday: “We haven’t spoken about it at all. It was actually not a topic we focused on.”

Richardson said she used cannabis in a “state of emotional panic” after learning of the death of her biological mother from a reporter one week before the trials took place.

“I know what I did,” Richardson told NBC News Friday. “I know what I’m supposed to do ... I still made that decision.”

“We are incredibly sympathetic toward Sha’Carri Richardson’s extenuating circumstances and strongly applaud her accountability — and will offer her our continued support both on and off the track,” the USATF said in a written statement, adding it believes the World Anti-Doping Agency rules regarding THC “would be re-evaluated.”

But its statement continued: “All USATF athletes are equally aware of and must adhere to the current anti-doping code, and our credibility as the National Governing Body would be lost if rules were only enforced under certain circumstances.

“While our heartfelt understanding lies with Sha’Carri, we must also maintain fairness for all of the athletes who attempted to realize their dreams by securing a place on the U.S. Olympic Track & Field Team.”

Fans continue to push for her reinstatement, calling the pot ban “outdated and arbitrarily enforced.”

A “Let Sha’Carri Run!” petition sponsored by MoveOn Civic Action, a progressive lobbying group, has garnered more than 526,000 signatures since July 2.

“In no world is marijuana a performance-enhancing drug for runners, and in more places in the United States and around the world, marijuana use is legal,” the petition reads. “The imposition of a penalty against a world-class Black, queer, woman athlete is powerfully and infuriatingly reminiscent of the way drug laws are regularly applies in the United States. Recreational marijuana use has been de facto legal for upper-middle-class white people for years – something more states are recognizing as they legalize marijuana for all people and consider how to repair the damage done to Black and brown communities by decades of the ‘war on drugs.’

“The world is coming together for a Summer Olympics postponed by a global pandemic,” the petition continues, “and we deserve to see the best athletes in fair, open competition. That includes Sha’Carri Richardson, whose one-month penalty is excessively punitive for an irrational, outdated rule.
