Chain smoking is the practice of smoking several cigarettes in succession, sometimes using the ember of a finished cigarette to light the next. Often the term chain smoker refers to a person who smokes relatively constantly, not necessarily chaining each cigarette. The term applies primarily to cigarettes, although it can be used to describe incessant cigar and pipe smoking as well. It is a common form of addiction.

Heating, ventilating, and air conditioning (HVAC) professionals claim that an airflow of about 1000 cubic feet (28.32 cubic meters) per minute per smoker is required to maintain satisfactory air quality when the smokers are chain smoking. However, research confirms that current HVAC systems, while important for general air quality, cannot control exposure to secondhand smoke.
