Smoking and tobacco use can have serious negative health consequences: - More than 1,000 Americans die each day from smoking-related illnesses. Tobacco is toxic, addictive, and can kill users by taking away years of their lives. - Cigarettes contain over 7,000 chemicals, many of which are toxic, including carbon monoxide, formaldehyde, arsenic, cyanide, and over 70 cancer-causing agents. - Both smoking and exposure to secondhand smoke increase risks of cancer, heart disease, lung disease, premature birth, and infant death. Quitting smoking can reduce health risks.
