Smoke
Smoke is a collection of airborne solid and liquid particulates and gases emitted when a material undergoes combustion or pyrolysis, together with the quantity of air that is entrained or otherwise mixed into the mass. It is commonly an unwanted by-product of fires (including stoves, candles, oil lamps, and fireplaces), but may also be used for pest control (cf. fumigation), communication (smoke signals), defensive and offensive capabilities in the military (smoke-screen), cooking (smoked salmon), or smoking (tobacco, cannabis, etc.). Smoke is used in rituals, when incense, sage, or resin is burned to produce a smell for spiritual purposes. Smoke is sometimes used as a flavoring agent, and preservative for various foodstuffs. Smoke is also a component of internal combustion engine exhaust gas, particularly diesel exhaust.

Famous quotes containing the word smoke:
“Smoking ... is downright dangerous. Most people who smoke will eventually contract a fatal disease and die. But they don’t brag about it, do they? Most people who ski, play professional football or drive race cars, will not die—at least not in the act—and yet they are the ones with the glamorous images, the expensive equipment and the mythic proportions. Why this should be I cannot say, unless it is simply that the average American does not know a daredevil when he sees one.”
—Fran Lebowitz (b. 1950)
“If in that Syrian garden, ages slain,
You sleep, and know not you are dead in vain,
Nor even in dreams behold how dark and bright
Ascends in smoke and fire by day and night
The hate you died to quench and could but fan,
Sleep well and see no morning, son of man.”
—A.E. (Alfred Edward)
“There is in every American, I think, something of the old Daniel Boone—who, when he could see the smoke from another chimney, felt himself too crowded and moved further out into the wilderness.”
—Hubert H. Humphrey (1911–1978)
