Smoking kills about 1,200 people in the United States every day, and a person who smokes dies on average 7 years earlier than a non-smoker. Tobacco contains numerous toxic and carcinogenic ingredients like arsenic, formaldehyde, benzene, and radioactive polonium. Most smokers get addicted to nicotine before the age of 18 and are influenced by peer pressure and a desire to be seen as "cool". Quitting smoking can significantly improve one's health and quality of life by living longer and reducing the risk of cancer and other illnesses.
