Smoke - Definition and Overview

For the movie starring Harvey Keitel, see Smoke (movie); for the cigar aficionado magazine, see Smoke (magazine)

Smoke is a suspension in air of small particles resulting from incomplete combustion of a fuel. It is commonly an unwanted by-product of fires (including in stoves and lamp), but may also be used for pest control, communication (smoke signals) or inhalation. Smoke sometimes also is a component of internal combustion engine exhaust gas, particularly diesel exhaust.

Smoke inhalation is a common cause of death in victims of indoor fires. The smoke kills by a combination of thermal damage, asphyxiation and pulmonary irritation.
