Effects of Smoke

Some people chew the tobacco while other use it in cigarettes. Tobacco smoke consists of many chemical substances. Nicotine tar and carbon monoxide are the most important chemical substances. Nicotine is a very poisonous chemical compound which causes addiction and which makes difficult to quit smoking in the smokers. Another most important effect of nicotine on the human body is that it causes the narrowing of the blood vessels which hinders the blood supply to all the organs of the body.

Effects of Smoke
Tar is a gelatinous material which collects around the lung tissues and the function of the lung is affected. Tar also causes lung cancer.Carbon monoxide present in the cigarette smoke combines with the hemoglobin of the blood and reduces the oxygen content of the blood. Because all the tissues of the body require oxygen for their proper function, just to compensate the low oxygen supply, the heart has to work more, which causes more burdens on the cardiac muscles. These are some of the reasons, that smokers have more incidences of heart diseases than the non-smokers.

Man is making progress in industries. The population of the world is also increasing at a rapid pace. Along with the human activities, the amount of smoke is also increasing in the atmosphere, industrial and domestic. The smoke consists of carbon monoxide, chlorofluorocarbon, (CFC’s) oxides of nitrogen and sulphur.

This smoke collects below the ozone layer and by increasing its thickness. It causes rise in temperature of atmosphere of earth and that changes the climate. Sometime these gases in smoke start eating ozone and produce holes in ozone layer. These holes in ozone layer cause genetic mutations in the man, plants and animals. It also increases the incidence of skin cancers in the humans.

Respiratory Diseases due to Smoking

Cigarette smoke causes the inflammation of the bronchi, bronchioles and the lungs which is the main reason of cough and sputum. The inflammation of the wind pipe (trachea) and bronchi is called bronchitis. The smoking damages the air sacs in the lungs. This reduces the oxygen exchange in the blood. The patient has to breathe faster to compensate this if causing damage to him. This disease is called emphysema.
