nguage and Culture Notes
1.Background information
The harmfulness of smoking to health is increasingly being recognized. Research has shown that smoke from the average cigarette contains around 4,000 chemicals, at least 43 of which cause cancer. Its major component, nicotine, is both poisonous and addictive. Recent research has focused on the effects of environmental tobacco smoke (ETS)－that is, the effect of tobacco smoke on nonsmokers who must share the same environment with a smoker. It is estimated thatexposure to ETS, which contains all the toxic agents inhaled by a smoker, causes 3,000 cancer deaths and an estimated 40,000 deaths from heart disease per year among nonsmokers in the U.S. alone. Hence, anti-smoking groups around the world are working very hard to try to persuade their governments to ban smoking in all public places.
