There are many dangers of smoking to the body, to the immediate family, to the society, to the environment and to the economy. More than 700 chemical additives are found in cigarettes. Some of them are classified as toxic and are not allowed in food.

Once lit, a cigarette reaches a temperature of nearly 2,000 degrees Fahrenheit. This high heat helps release thousands of chemical compounds, including poisons like carbon monoxide and hydrogen cyanide, at least 43 carcinogens, and numerous mutagens. All of these are drawn into the body when a smoker inhales.

One more of the dangers of smoking are Carbon monoxide. Smoking also increases the level of carbon monoxide in the lungs. This poisonous gas is quickly absorbed into the blood, reducing its capacity to carry oxygen.

As a result, the smoker has to exert more physical effort to attain a given task than does a nonsmoker. The heart in particular must work harder, particularly during rigorous exercise. Increased levels of carbon monoxide in the blood can impair vision, perception of time, and coordination.
