Brittney Griner was back in a Russian courtroom on Friday and a lawyer for the WNBA star presented a doctor's note recommending the use of medical cannabis in order to treat pain. 

Griner, who pleaded guilty to drug charges on July 7, has been held in Russia since February after Russian authorities say they found vape cartridges containing hashish oil in her luggage. The guilty plea does not bring an end to the trial.

"The attending physician gave Brittney recommendations for the use of medical cannabis. The permission was issued on behalf of the Arizona Department of Health," lawyer Maria Blagovolina said.

Griner’s lawyers also presented evidence that Griner had undergone anti-doping tests, which did not return any positive results. 

In recent weeks, there has been mounting pressure on the Biden administration to bring the two-time Olympic gold medalist home, with news coming to light that Griner penned a letter to President Biden asking for his help in obtaining her release from a Russian prison and her safe return to the U.S.
