Marijuana?

A man in a blue shirt with white stripes on the sleeves is bent over inside a confined space, likely a vehicle, with his head down and mouth open, appearing to be in distress or discomfort. A hand holds up a clear plastic bag filled with a green, leafy substance, which is visible in the foreground. The man remains in a hunched position throughout the loop, with his head moving slightly, while the bag of substance is held steady. The setting appears to be the interior of a vehicle, possibly a train or bus, with white walls and a handrail visible. The text overlay in Russian reads "КАЛИНИНГРАД"
