According to the White House, Russia made a "bad faith" response to a U.S. offer for a prisoner swap, which resulted in a nine-year prison sentence for a basketball player.
The man has to pay a fine of one million ruble.
The Russian court said the crime was committed deliberately.
She apologized to her teammates, her club, fans and her family, saying she never meant to put the Russian population at risk.
The ruling comes a week after Secretary of State Antony Blinken pressed Russia's Foreign Minister Sergei Lavrov to accept a deal to swap two Americans for a Russian weapons dealer.
According to her lawyers, she uses cannabis for medical reasons and unintentionally packed the e-liquid while rushing.
The sentencing was severe by Russian legal standards, and proves that she is being used as a political pawn.
President Joe Biden said in a statement that Russia's punishment was "unacceptable" and called on the country to release her immediately.
In closing arguments, he said that he hoped that the ruling wouldn't end his life. I hope that politics is far away from this courtroom.
The two-time Olympic gold medal winning gymnast pleaded guilty to drug charges on July 7. Her attorneys argue that she didn't intend to break the law when she used medical marijuana in the U.S. She testified for the first time last week that she was not read her rights after being arrested, that she was not offered an attorney, and that she was forced to sign papers without a translator. Last week, U.S. officials said they had proposed a prisoner swap in exchange for Griner, and that they had also offered Bout in exchange for her. Bout supplied millions of Soviet-era weapons to militias and terror groups around the world.
John Kirby called Russia's attempt to add another prisoner to the swap a "bad faith attempt to avoid a very serious offer" on CNN last week.
The Russian prosecutor says that Griner should be imprisoned for 9 1/2 years.
The Russian prosecutors want a 9 1/2-year sentence for the man.
Russian officials requested that a convicted murderer be added to the prisoner swap.
