A papirosa (Russian: папироса, plural: papirosy) is an implement for tobacco smoking, a variant of cigarettes.
[3] The inner end of the mouthpiece is cut into dents which are bent to keep tobacco from travelling into the mouth.
[5] While smoking, the mouthpiece is usually compressed to create two separate perpendicular flat surfaces, with one of them going into the mouth.
It is claimed that Joseph Stalin's favorite tobacco to stuff his pipe was from Herzegovina Flor [ru] papirosy.
[6] It is possible that this is just a legend: the pipe requires a large cut of tobacco, otherwise it burns quickly.
