Russian customs officials found "multiple" vape pen cartridges in Brittney Griner's carry-on bag when she was detained at a Moscow airport in February.

Griner, 31, was arrested after a search of her luggage turned up various vape pen cartridges. Each cartridge contained a gram of marijuana oil extract.

Russian Federal Customs Service announced her arrest on Saturday, March 5. She was accused of transporting illegal drugs into the country - a charge that carries up to 10 years in prison if convicted.

According to MSN News, U.S. Secretary of State Antony Blinken said Pres. Joe Biden assigned an embassy team to work on Griner's case in Moscow.

However, U.S. diplomats working to release Griner were informed that customs officials found "multiple" weed oil cartridges in her luggage. The amount was more than a small quantity for "personal use."

Personal use drug possession is a misdemeanor in the United States.

NBA legend Reggie Miller is among those calling for Griner's release.

"I hope for a safe passage back for Brittney," said Miller, whose sister is Women's Basketball Hall of Famer Cheryl Miller.

"Again, you know, not knowing all the particulars, I know it's not right for them to detain her," Miller said. "I don't even think we know where she is, I'm sure the State Department does, but there's still very little information that's coming out of Russia right now. That's what's a little bit disturbing."

The Baylor University star was the No. 1 overall draft pick by Phoenix in 2013. The seven-time WNBA All-Star came out as a lesbian that same year.

Gays and lesbians face social challenges in Russia where homosexuality is frowned upon.

Griner earned $1.5 million a year in Russia — 6 times her WNBA base salary of $215,000. She won championships for Russia in 7 seasons.
