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- *** oking is a widespread habit.About forty-three percent of the *** men and thirty-one percent of the *** women in the United States *** oke cigarettes regularly.Men,as a group, *** oke more than women.
Ine,education and occupation all play apart in determining a person’s *** oking habits.City people *** oke more thanpeople living on farms.Well-educated men with high ines are less likely to *** oke cigarettes than men with fewer years of schooling and lower ines.Onthe other hand if a well-educated man with a high ine *** okes at all,he islikely to *** oke more packs of cigarettes per day.
The situation is somewhat different forwomen.There are slightly more *** okers among women with higher family inesand higher education than among the lower ine and lower educational groups.These more highly-educated women tend to *** oke more heavily.
Among teenagers,the picture is similar.There are fewer teenage *** okers from upper-ine,well-educated families and fewer from families living in farm areas.Highschool students who are preparing for college are less likely to *** oke thanthose who do not plan to continue their education after high school.Childrenare most likely to start *** oking,if one or both of their parents *** oke.(284words)
