Tobacco
Smoking, directly and indirectly, causes more death and illness in the United States than any other single activity. Each year, more than 300,000 Americans die of smoking-related illnesses, including lung cancer, emphysema, and heart disease. Although the incidence of smoking among men has declined to about 32 percent from its peak of 54 percent in the mid-1950s, smoking remains one of the most difficult habits to kick. Much of what is known today about the harmful effects of tobacco was learned from medical studies of the effects of cigarette smoking on the lungs. The effects of smoke from cigars and pipes are also dangerous, although in somewhat different ways (see Post Harmful Effects of Smoking and Physiological Effects of Smoking).
