Smoke grenades are functionally identical to many forms of [[United States hand grenades#Chemical grenades|chemical grenades]] (such as [[CS gas]] [[riot control]] grenades) and [[United States hand grenades#Incendiary grenades|incendiary grenade]]s (such as [[thermite]] grenades) which use a fuse to ignite a solid filler inside a steel canister, which then slowly propels the combustion products out through holes in the canister as the contents burn. However, the smoke grenade class is restricted to signaling and concealment under the [[law of war]], and thus they are not considered weapons; since the vast majority are non-explosive, they remain legal for civilian use and ownership in most countries.

Since the basic design of a smoke grenade (a metal canister containing a substance that burns and expels smoke when ignited) is simple, improvised smoke grenade-like devices are ubiquitous across the world. Protestors, football spectators, and [[airsoft]] enthusiasts often create their own smoke grenades using common materials.
