KHIMKI, Russia, July 15 — Lawyers defending US basketball player Brittney Griner told a Russian court today she was prescribed medical cannabis in the United States for a chronic injury, a Reuters journalist at the courtroom reported.

Griner pled guilty to drugs charges which carry a prison sentence of up to ten years after she was detained at a Moscow airport in February carrying vape cartridges with hashish oil.

The Women's National Basketball Association (WNBA) star appeared in court wearing a Nirvana t-shirt today for the fourth hearing in the trial. She has said she did not intend to break the law, and US President Joe Biden has said the United States is doing everything it can to secure her release.

The Kremlin has downplayed the idea of a prisoner exchange, saying it is premature to discuss the possibility of swapping Griner, a two-time Olympic gold medallist, for a Russian imprisoned in the United States.

Griner's defense team submitted documents today to support her case that she did not intend to bring drugs into Russia illegally in the hopes of securing a more lenient sentence. In them, they said Griner suffered from chronic pain and that she had a permit issued in the state of Arizona for the use of medical cannabis.

In a hearing yesterday, a Russian basketball club director gave evidence in support of Griner, speaking of her "outstanding ability" and "personal contribution to strengthening team spirit."

Griner, who plays for the Phoenix Mercury in the United States was scheduled to play for Russian team UMMC Ekaterinburg in the off-season - a common move for WNBA players. Griner first played in Russia in the 2014-15 season, and had prior stints in China. — Reuters
