It is axiomatic that tobacco smoking is hazardous to health. The statistics are well documented and often very grim. For example, the 2008 World Health Organization Report on the global tobacco epidemic presented the following statistics: a hundred million people died of tobacco-related diseases globally in the 20th century; there are approximately over five million tobacco-related deaths every year; and an estimated one billion could die of tobacco-related diseases in this 21st century.
Significantly, no other risky, self-indulgent addictive behaviors such as cocaine abuse directly endanger bystanders as much as cigarette smoking or tobacco use endangers nonsmokers through secondhand tobacco smoke or inhaled environmental tobacco smoke (ETS). Environmental tobacco smoke comprises sidestream smoke (smoke that emanates from the burning end of a tobacco product) and mainstream smoke (smoke exhaled by the smoker). About 85 percent of environmental tobacco smoke is sidestream smoke, while the remainder is mainstream smoke.
