Tobacco smoke that is exhaled by smokers. Mainstream smoke can be a form of secondhand smoke. It contains nicotine and many harmful, cancer-causing chemicals. Inhaling mainstream smoke increases the risk of lung cancer and may increase the risk of other types of cancer. Inhaling it also increases the risk of other health problems, such as heart ...
Mainstream smoke (MS) is the aerosol drawn into the mouth of a smoker from a cigarette, cigar, or pipe. Sidestream smoke (SS) is the aerosol emitted in the surrounding air from a smoldering tobacco product between puff-drawing. SS is a major source of environmental tobacco smoke (ETS), i.e., air pollution caused by the burning of tobacco products. Other contributors to ETS are the exhaled ...
mainstream smoke: Smoke released by a burning tobacco product and directly inhaled by the smoker. Synonym: first-hand smoke See also: smoke
Secondhand smoke (sometimes called passive smoke, environmental tobacco smoke, or involuntary smoke) is a mixture of sidestream smoke (the smoke from the burning tip of a cigarette or other smoked tobacco product) and mainstream smoke (smoke exhaled by a smoker that is diluted by the surrounding air) (1–3).
Sidestream smoke is the main component (around 85%) of second-hand smoke (SHS), also known as Environmental Tobacco Smoke (ETS) or passive smoking. The relative quantity of chemical constituents of sidestream smoke are different from those of directly inhaled ("mainstream") smoke, although their chemical composition is similar.
Sep 21, 2023 · Sidestream smoke (SSM) is the smoke that is emitted from the burning end of a cigarette, cigar, or pipe. It contains many harmful chemicals and pollutants, including carcinogens, which are known to cause cancer. On the other hand, mainstream smoke (MSM) is the smoke that a smoker inhales and then exhales into the surrounding environment.
