Smoking (tobacco addiction) is a serious illness that, fortunately, is curable, although it is not easy to get rid of it. Since nicotine addiction is similar to drug addiction, smoking cessation will be perceived by the body very hard.
Cigarette smoke contains about 4 thousand substances, many of which are hazardous to health. The most important of these are:
Nicotine – an alkaloid, acting on the central nervous system, causes nicatin addiction (like drug addiction). It makes the heart work faster. By narrowing blood vessels, including coronary arteries, nicotine negatively affects the blood supply to the heart. Nicotine sulfate is used in agriculture for pest control.
Resins – are deposited in the lungs, causing irritation to the respiratory tract. They are the leading cause of lung cancer.
Carbon monoxide (the same as in car exhaust), getting into the blood through the lungs, reduces the amount of oxygen in it, which causes a lack of oxygen in all blood-fed organs, including the brain. Over time, the constantly high presence of carbon monoxide in the blood leads to vascular hardening, which increases the risk of cardiovascular disease.
Nicotine increases blood pressure and increases heart rate. Due to smoking, coronary heart disease, angina pectoris can develop, and the level of cholesterol in the blood rises prematurely. Smoking also slows down blood flow in the vessels, increasing the likelihood of blood clots, and damages the inner walls of blood vessels, contributing to the development of atherosclerosis. Under the influence of smoke, a cough develops, the secretion of sputum is activated, chronic bronchitis of a smoker, ephysema of the lungs develops. Asthma attacks are more frequent and more severe. Smoke provokes acute respiratory diseases.
Smoking stimulates the secretion of gastric acid, which can cause heartburn and increase the chance of stomach and duodenal ulcers. It can also negatively affect liver function and accelerate the course of alcohol-related liver disease.
Chronic obstructive pulmonary disease (COPD): This is a group of health conditions that blocks the flow of air and thus one will have difficulty breathing. COPD causes health dysfunctions like chronic bronchitis and emphysema. Emphysema when there is shortness of breath because the alveoli or air sacs have been damaged. Chronic bronchitis leads to frequent coughing with a lot of mucus. Smoking 80% accounts for about 80% of COPD patients. Lungs decline at a faster rate, 3 times actually in smokers than the normal rate. Shortness of breath begins due to lung dysfunction.

Cancer: Smokers are more likely to get cancer; Cancers of the lungs, throat, pharynx and mouth are caused by a carcinogen that is present in tobacco smoke. It comes close that 90% of lung cancer cases are associated with smoking.

Other cancers associated with smoking are cancers of the bladder, pancreas, kidney and esophagus, and cervical cancer is more common in women who smoke.

Cardiovascular disease: This is a disease of the heart, blood vessels, including arteries and veins. The main causes of smoke related deaths fall into this category. As it was previously found that nicotine increases blood cholesterol levels, these and other fats are deposited in the arteries.
Therefore, the arteries become stiff, narrow, or blocked. Due to this narrowing of the arteries, there will be blood clots and therefore the risk of cardiovascular disease. Common cardiovascular disease is peripheral vascular disease, coronary thrombosis, coronary heart disease, cerebral thrombosis and cerebral diseases like stroke.

The lining of blood vessels is damaged, this affects the level of fat in the bloodstreams, increases the risk of atheroma, it is the main source of stroke, aneurysm and heart disease. In addition, smoking causes mouth ulcers.

Smoking has been linked to sexual problems, from productivity in the field to infertility. Continued smoking increases the risk of high blood pressure. Pale skin and more wrinkles caused by decreased vitamin A levels, smokers have a lower blood supply to the skin.

During pregnancy, it is advisable not to smoke, as it increases the risk of miscarriage, complications such as bleeding, ectopic pregnancy, premature birth and abruption of the placenta. Also stillbirths, low birth weight or birth defects such as cleft palate.
Tobacco smoking is the main cause of heart disease, bronchitis, and stroke. It contributes to the complication of colds and pneumonia. Tobacco is harmful to women’s health and is associated with an increased risk of miscarriage, premature birth, stillbirth and infant death, and is also associated with low birth weight in infants.
Oncological diseases
Almost everyone knows that smoking can cause lung cancer. But the truth is that smoking increases the risk of other cancers, such as cancers of the oral cavity, larynx, esophagus, stomach, pancreas, bladder, kidney, and even some types of leukemia.

Heart attack, vascular disease

Smokers are twice as likely to die from heart disease as non-smokers. Smoking can be the cause of vascular diseases, affect the blood circulation processes. Due to the deterioration of blood circulation, many male smokers sooner or later face the problem of impotence.

Some other problems

Smoking increases the risk of pathological changes in the structure of the macular retina, which very often cause blindness in old age. Smokers have trouble sleeping and have to whiten their teeth more often. The characteristic features of a smoker’s appearance include premature wrinkles, yellowed nails, and bad breath.

Special risks for female smokers

Women over 35 years old should not take hormonal contraceptive drugs, as this can lead to the development of thrombosis. Smokers are more likely to suffer from premature termination of pregnancy, as a rule, they give birth to weak and sickly children. Smoking causes us to lose years of our lives
It is known that an adult male smoker, with his addiction to smoking, deletes from his life an average of 13 years, a smoker – about 15. But even before the fatal end, diseases caused by smoking can significantly affect the quality of life itself. Difficulty breathing, limited mobility, disability.
When a person picks up a white cigarette, lights it, then, of course, smoke comes out. And the poisons of this smoke, acting on the nerve endings embedded in the skin, cause skin paresthesia – it seems to a person that some small insects are crawling along the skin. Sometimes even underwear is so itchy that a person is deprived of sleep. Well, it’s all outside.


Special risks for female smokers

The essence of the disease is as follows. When a person at home or at work … or on the street … takes out a white cigarette from a rustling pack and lights it, the chemicals contained in the smoke penetrate into his lungs and then into the blood. And under the influence of these chemicals contained in the smoke, the arteries of the limbs, the arteries of the arms and legs, begin to overgrow. Narrowing of the lumen of the blood vessel leads to tissue malnutrition. In the initial stage, this disease manifests itself with symptoms such as chilliness of the legs, numbness of the fingers, then lameness sets in, then the skin becomes purple-blue and begins to gradually turn black, ulcers form on it, gangrene begins, that is, rotting of the dead parts of the leg. The treatment has no effect without smoking cessation. And if a person does not give up smoking, his fingers, foot, etc. are cut off.
If, in this case, the smoker does not part with the cigarette, the process immediately switches to the other leg, and then to the hands.

And a lot here depends on human genetics.

The data of the medical literature indicate that in fact every smoker to one degree or another is sick with the disease that in the future will turn into gangrene of the legs. A person started smoking at the age of 14, and from the age of 14 this process of clogging of the arteries has already begun.
Therefore, we resolutely gave up smoking, gave up cigarettes, because you can’t go far without legs, right? A person who has given up smoking walks on their own feet.
