“Tobacco smoke and the habit associated with it, smoking, are the most obvious cause of damage to the body, but they do not lose their relevance.”

Why is smoking harmful?

Most people start smoking at an age when the harmful effects of tobacco are not noticeable and the body’s reserves are even greater.

According to the WHO, smoking is the leading cause of premature death (more than 8 million people die each year from tobacco-related diseases) and is also responsible for the development of most chronic non-communicable diseases.

For those who start smoking regularly during adolescence, the risk of dying from tobacco consumption increases to 50%. Death occurs in middle age, which corresponds to 22 years of lost life expectancy.

Smoking is responsible for 90% of lung cancer cases. Given the accompanying changes, such as chronic bronchitis, early radiological changes may be missed, leading to tumor diagnosis at later stages.

Clinical protocols for the examination and treatment of patients with lung cancer always take smoking into account; The scope of the examination of the tumor tissue, the prognosis of its aggressiveness and the choice of therapy will depend on this.

The carcinogenic properties of smoke also extend to the organs that interact with it, such as the larynx, esophagus, throat, tongue and oral cavity. Cancer in these locations is very aggressive: mutilation and appearance alteration operations are used during treatment.

The nicotine itself and carbon monoxide contained in tobacco smoke damage the endothelium, the inner wall of blood vessels, blood flow is disturbed, cholesterol levels increase, and these factors together contribute to the formation of atherosclerotic plaque. Consequently, the risk of suffering a stroke increases.

Chronic smoking is characterized by more active reactions associated with adrenaline and norepinephrine, and a more rapid vascular reaction (myocardial infarction associated with vascular spasm caused by smoking) provides less time for the possibility of resuscitation.
