Up to six athletes are selected for the country’s relay group, and four of them must be the top three in the 100 meters at the Olympic Trials and as a substitute. The governing body appoints the other two members of the relay pool.
In one declaration, USA Track & Field said Richardson’s situation “is incredibly unfortunate and devastating for everyone involved,” but made no mention of whether or how she would compete in the Olympics.
Richardson’s agent Renaldo Nehemiah did not respond to a phone call or text on Thursday.
Essentials of the Summer Olympics
Marijuana is on the World Anti-Doping Agency’s list of prohibited substances. USADA and the United States Olympic and Paralympic Committee are both signatories to the AMA code, which means they follow its rules.
“Although we are heartbroken, the USOPC is steadfast in its commitment to clean competition and supports the anti-doping code,” the organization said in a statement Friday morning. “Testing positive for any banned substance has consequences and we are working with the USATF to determine the appropriate next steps. We are committed to providing Sha’Carri with the support services she needs during this difficult time. “
Marijuana is prohibited only during competition times, which are defined as starting at 11:59 p.m. the day before a competition and ending at its end. Athletes can have up to 150 nanograms per milliliter of THC, the main psychoactive substance in marijuana, without causing a positive test.
According to USADA, marijuana is a banned substance because it can improve performance, poses a health risk to athletes, and its use violates the spirit of the sport.
