More than sixteen million people are said to be living with a disease caused by smoking. The list of diseases goes on and on, from eye diseases to tuberculosis, and many of them lead to death. Every year almost six million people die from causes related to tobacco use. It is proven that smoking alone is responsible for around 480,000 deaths, to simplify it is around 1,300 every day. Just some of the chemicals that make up a cigarette include acetone, found in enamel, arsenic, found in rat poisoning, benzene, found in rubbery concrete, and they also include the well-known and highly addictive stimulant, nicotine found as an insecticide.
