Untilthetwentiethcenturycigaretteswerenotanimportantthreat(威胁)topublichealth.Menusedt... Until the twentieth centurycigarettes were not an important threat (威胁) to public health. Men used tobacco mainly in the form of cigars, chewingtobacco, pipe tobacco, and snuff (鼻烟). Most women did not usetobacco at all.
The cigarette industry began in the 1870swith the development of the cigarette making machine. This made it possible toproduce great numbers of cigarettes very quickly, and it reduced the price.Today cigarette-smoking is a widespread habit. About forty-three percent of theadult men and thirty-one percent of the adult women in the United Statessmoke cigarettes regularly. Men, as a group, smoke more than women.
Income, education and occupation all play apart in determining a person’s smoking habits. City people smoke more thanpeople living on farms. Well-educated men with high incomes are less likely tosmoke cigarettes than men with fewer years of schooling and lower incomes. Onthe other hand if a well-educated man with a high income smokes at all, he islikely to smoke more packs of cigarettes per day.
The situation is somewhat different forwomen. There are slightly more smokers among women with higher family incomesand higher education than among the lower income and lower educational groups.These more highly-educated women tend to smoke more heavily.
Among teenagers,the picture is similar. There are fewer teenage smokers from upper-income,well-educated families and fewer from families living in farm areas. Highschool students who are preparing for college are less likely to smoke thanthose who do not plan to continue their education after high school. Childrenare most likely to start smoking, if one or both of their parents smoke. (284words)
