Smoke Bomb

A smoke bomb (発煙弾, Hatsuen-dan) creates a cloud of smoke when it detonates. In Naruto, smoke bombs look like small spheres wrapped in paper. Smoke bombs are typically used to blind opponents and make them easier to attack. Alternatively, ninja can use smoke bombs on themselves so that opponents cannot see what they are doing.

Smoke bombs are not restricted to smoke, and can instead be used to store sleeping gas or toxic gas.
