Tobacco smoke is an aerosol consisting of liquid and solid particles in suspension. It contains nicotine, carbon monoxide, ammonia, hydrocyanic acid, hydrogen cyanide, acetone and a significant amount of substances that can cause the formation of malignant tumors.
Nicotine is the most dangerous. In tobacco smoke from one cigarette it contains 1800 mcg. The body gets used to nicotine quickly, so acute poisoning with it has a very short phase. Its symptoms: dizziness, cough, nausea, bitterness in the mouth. Sometimes they are joined by weakness, malaise, pallor of the face.
Carbon monoxide (carbon monoxide), which is formed during the burning of tobacco, is 300 times faster dissolved in the blood of a smoker than oxygen. This leads to oxygen starvation of the body, which primarily affects the heart.
These and other components of tobacco smoke are affected primarily by the pulmonary system: airways and lung tissue. They gradually destroy the mechanisms of lung protection, causing pulmonary diseases. As a result of irritation of the mucous membrane of the larynx, trachea, bronchi and alveoli (pulmonary vesicles), a chronic disease of the respiratory tract develops – bronchitis. It affects 80% of smokers. In addition, the mode of oxygen entry into the bloodstream is violated, oxygen starvation of the body occurs, emphysema develops (expansion of the pulmonary vesicles – alveoli).
