American basketball player Brittney Griner was detained by Russian customs at an airport on 17 February 2022 after officials said her luggage held vape cartridges containing cannabis oil.[1][2] Customs officers at Sheremetyevo International Airport outside Moscow found less than a gram of hash oil in the cartridges.[3] Her lawyers said she used cannabis for medical reasons, and she said she had been prescribed medicinal cannabis in Arizona.[3] Her trial began in July 2022 and she pleaded guilty while saying she had packed the cannabis oil by accident.[4]

On 4 August 2022 the Khimki Court outside Moscow found Griner guilty of drug charges and sentenced her to nine years in prison.[4] The court also fined her 1 million roubles, about $16,301.[4] The charge carried a penalty of up to 10 years, and prosecutors had asked for nine and a half years.[4] Griner asked the court for leniency and said she had never meant to hurt anybody or to break any laws here.[4]

In October 2022 a Russian court rejected her appeal.[1] On 8 December 2022 she was released in a prisoner exchange for the Russian arms dealer Viktor Bout, who was serving a 25-year sentence in a US federal prison.[1][2] Before the sentence, the US State Department said Griner was being wrongfully detained.[3]

The prisoner trade took place in the United Arab Emirates.[2]
