Passive smoking is the inhalation of tobacco smoke, called passive smoke, secondhand smoke (SHS) or environmental tobacco smoke (ETS), by individuals other than the active smoker. It occurs when tobacco smoke diffuses into the surrounding atmosphere as an aerosol pollutant , which leads to its inhalation by nearby bystanders within the same ...
The "population-attributable fraction" (PAF)—that is, the share of cancer deaths that could be prevented if a given risk factor were removed—is 28.5 percent for cigarette smoking and 0.7 ...
Third-hand smoke is contamination by tobacco smoke that lingers following the extinguishing of a cigarette, cigar, or other combustible tobacco product. [1] First-hand smoke refers to what is inhaled into the smoker's own lungs, while second-hand smoke is a mixture of exhaled smoke and other substances leaving the smoldering end of the cigarette that enters the atmosphere and can be inhaled by ...

This smoke is known as second-hand smoke (SHS) or environmental tobacco smoke (ETS) when the burning end is present, and third-hand smoke after the burning end has been extinguished. Because of its negative implications, exposure to SHS has played a ...

Nonsmokers who are exposed to second-hand smoke at home or work increase their heart disease risk by 25–30% and their lung cancer risk by 20–30%. Second-hand smoke has been estimated to cause 38,000 deaths per year, of which 3,400 are deaths from lung cancer in nonsmokers. [120]
The report criticized the Environmental Protection Agency (EPA) for their 1993 study about the cancer risks of passive smoking, calling it "junk science". Singer told CBC's The Fifth Estate in 2006 that he stood by the position that the EPA had "cooked the data" to show that second-hand smoke causes lung cancer.
Sidestream smoke is the main component (around 85%) of second-hand smoke (SHS), also known as Environmental Tobacco Smoke (ETS) or passive smoking. [2] The relative quantity of chemical constituents of sidestream smoke are different from those of directly inhaled ("mainstream") smoke, although their chemical composition is similar. [ 3 ]
