Onyx Rapper Fredro Starr Talks Brittney Griner Sentence, Smoking Weed in Russia

Brittney Griner's plan to appeal her 9-year Russian prison sentence over a weed pen is underway ... but Onyx rapper Fredro Starr feels there are bigger political forces in play.

In a new interview clip from VladTV, Fredro actually admitted to smoking plenty of weed on Russian soil on several occasions!!!

According to Fredro's travels, Russia not only has better weed than top dog California, but they grow it too ... and from the picture he paints, recreational use sounds pretty common in the region.

He also suggests the country's hip hop scene is very liberal, alluding to the notion a 9-year punishment for a simple weed pen doesn't add up.

Griner officially filed her appeal on Monday, in conjunction with the United States government actively working for her release, calling her detainment unjust.

The last time we talked to Fredro, he was talking about a different kind of smoking ... as in torching Cypress Hill during their somewhat underpromoted Verzuz.
