In blood
A large number of chemicals with tobacco smoke enter the bloodstream through the lungs. Carbon monoxide (exactly the same as in car exhaust!) Replaces part of the oxygen in the blood. This causes a lack of oxygen in all organs, including the brain.
Nicotine
One of the chemical elements that enter the blood is nicotine. Nicotine is an alkaloid contained in tobacco (up to 2%) and some other plants. Strong poison; in small doses, it acts excitantly on the nervous system, in large doses it causes its paralysis (stopping of breathing, cessation of cardiac activity). Multiple absorption of nicotine in small doses during smoking causes nicotinism. Nicotine sulphate is used to control pests of agricultural plants.
Smoking and lungs
Cigarette smoke comes into direct contact with the lungs, greatly increasing the risk of cancer, pneumonia, emphysema, chronic bronchitis and other pulmonary diseases that make breathing difficult. Fortunately, many changes are reversible.
Smoking and heart
The effect of exposure to chemicals contained in tobacco smoke on the body is the main risk factor for developing myocardial infarction and other cardiac diseases.

Smoking and your body[/caption]Smoking and appearance
Smoking causes yellowing of teeth and nails, as well as increases the number of wrinkles and leads to the syndrome "The face of a smoker". From many years of smoking, the walls of the vessels begin to convulsively contract, and as a result, many small cracks form in the tissue. These injuries lead to very adverse consequences. First, the blood corpuscles acquire great stickiness, forming blood clots, and secondly, small scars appear, and the smooth internal surface of the vessels itself becomes rough. These roughnesses contribute to the onset of atherosclerosis.
Smoking and hearing
The study showed that smokers 1.7 times more often become deaf. Among those who smoke between the ages of 60 and 69, 56.4% are worse off hearing. Among nonsmokers, the hearing deteriorated in 35.5%. Among those who stopped smoking, 47.3% became afflicted with hearing loss.
Smoking and men's health
In men, smoking increases the risk of impotence.
Smoking and health of women
Smoking leads to many complications during pregnancy, such as a premature baby and a decrease in fertility. Smoking women also may experience an earlier onset of menopause. Smoking women are more likely to suffer from depression.
Smoking and diabetes
If you have diabetes and you smoke, you are at great risk of complications, including problems with the eye vessels and vessels of the extremities.
Smoking and cancer
Smoking can cause cancer in organs that come in contact with smoke, such as the lungs, throat and mouth. Since chemicals from the smoke penetrate the blood, cancer can occur in many other organs.
Autoimmune disease
In smokers, according to a recent study ( J Rheumatology, 11, 2001), the risk of developing an autoimmune disease of systemic lupus erythematosus is increased. It is an incurable disease characterized by inflammation and damage to tissues and organs throughout the body, including the joints, skin, heart, kidneys and central nervous system. Lupus is an autoimmune disease, that is, it occurs when the immune system mistakenly attacks the body's own tissues. The researchers found that those who continue to smoke, the likelihood of developing lupus is seven times greater than that of non-smokers. Those who have already quit smoking, this probability is almost four times more than those who have never smoked people. It is not surprising that cigarettes affect the tendency to autoimmune reactions, since in cigarette smoke there are at least 55 chemicals that affect cell growth or its viability, including carbon monoxide, cyanide, hydroquinone and others. It is also possible that smoking can trigger an autoimmune process in conjunction with other factors.
Data:
Smoking leads to the development of three major diseases with a fatal outcome: lung cancer; chronic bronchitis and emphysema; coronary disease.
In the case of several countries where smoking has become a mass habit for a long time, it has been proved that tobacco causes mortality:
- from lung cancer in 90% of all cases,
- from bronchitis and emphysema in 75%,
- from heart disease in about 25% of all cases.
Approximately 25% of regular cigarette smokers will die prematurely due to smoking. Many of this number could live for 10, 20 or 30 years longer, i.e. in this case the average loss of life years is significant. Deaths due to smoking on the average will lose 10-15 years of their lives.
In one European country (with a population of about 50 million people), the number of deaths due to smoking is equivalent to the number of deaths due to air crashes of high-capacity jet liners, assuming that such disasters - with the death of all people on board - will occur daily.
