Passive smoking
: The inhaling of environmental tobacco smoke (ETS) involuntarily by someone who is not smoking. Environmental tobacco smoke is generated from the sidestream (the burning end) of a cigarette, pipe or cigar or from the exhaled mainstream (the smoke puffed out by smokers) of cigarettes, pipes, and cigars. Environmental tobacco smoke was classified as a "known human carcinogen" by the US government in 2000, based on the causal relationship observed between passive exposure to tobacco smoke and human lung cancer and based also on studies that have conclusively shown an increased risk of lung cancer in nonsmoking women living with smoking husbands or working with smoking co-workers. Passive smoking is also called involuntary smoking.
