American Indians grew and smoked tobacco before Columbus came to America. The tobacco industry has been large and important for America’s economy ever since colonial farmers grew tobacco for export 300 years ago. Even today tobacco is grown in large quantities along America’s Eastern Coast. Since the 1800’s the most common form of smoking tobacco is in cigarettes. Men and women of all ages smoke cigarettes and there are dozens of brands sold in the U.S. Nearly all cigarettes now sold have filters. Pipe smoking has some popularity and cigars are usually only smoked by older men. Over the past fifteen years, many people have stopped smoking. This movement away from cigarettes began when lung cancer and other ailments were linked to smoking. In the 1970’s when taxes on cigarettes were greatly increased, cigarette smoking became much more expensive. Since the late 1970’s physical fitness has become a major aim of millions of Americans. These three factors have been the major causes for many people to stop smoking. Today in the U.S. cigarette smoking is restricted in many ways. When smokers are in restaurants, on trains and in public buildings, they may smoke only in designated areas. When they are on public buses, in theaters and in classrooms, they may not smoke at all. Cigarettes are not advertised on television or radio. A notice is on every package of cigarettes sold in America warning that smoking is dangerous to health. These regulations have reduced cigarette smoking very much since they were instituted. Smoking is on the decline.
