In November, 1959, questionnaires on smoking habits were answered by 6,810 students from grades 7 through 12, attending the public high schools in Newton, Massachusetts. In this report differences between smokers, discontinued smokers, and nonsmokers in the use made of leisure time activities and in their attitudes and beliefs about smoking and health are explored. Smokers spend a greaten amount of time watching television and less time reading books than do nonsmokers. Their friends are more often smokers, and they go to the movies more frequently, attend dances oftener, and are car owners more often than are nonsmokers. On the other hand, they play sports less and belong to fewer clubs and organizations than nonsmokers. More nonsmokers than smokers consider smoking to increase nervousness, to cause lung cancer, and to have a deleterious effect on growth, athletic ability, and health. Differences found between smokers and nonsmokers remain consistent within each social class.
