It has calculated that 51% of American men smoke while 34% of American women do so.Since 1930, scientific studies have shown time and again that smoking does great harm to ones health and that it will shorten ones life.Cigarette smoking is believed, to most research workers in this field, a very important cause in the development of cancer of the lungs and the cancer of the throat and is believed to have much to do with some other kinds of cancers. Cigarette smokers suffer from the illness of the heart more often than those who dont smoke.
