Pic only slightly related, it's a Russian artist. I'm looking for a movie I aw a few years ago, it was very sad and it was set in Russia. I believe it was made by Russians too.

The movie follows two young Russians, a teenage girl and a slightly younger biy, as they navigate the impoverished slav blocks they grew up in, getting high off of huffing glue all along. Eventually the boy dies, and she turns to prostitution, until finally she is trafficked to Scandinavia where she is enslaved until she escapes and an heroes. Anybody know it?
