The first news about tobacco in the medical literature of the Western world is from 1561, indeed, among Native American Indians, smoking tobacco was a common practice many centuries before the Spanish came to America. The researchers believe that the origin of the plant from which tobacco is derived is from the island of Tobago in the Caribbean Sea. From there the plant was brought to Portugal, and the French ambassador to Portugal, Nicot, sent a number of models to the Queen of France, Catherine Di Medici. This ambassador called the plant Nicotina after him, and so the name of the plant was accepted in scientific terms – Nicotina Tabakum.

A little science:
Cigarette smoke contains about four thousand different substances, some in the form of solid particles, and some in the form of gases. Some of these substances, especially the gas particles, are toxic to various body systems, and some are carcinogenic substances. Cigarette smoke is quickly absorbed through the lining of the airways, causing immediate symptoms such as blood vessel contraction, decreased skin temperature, and far-reaching effects. One of the most toxic substances studied is carbon monoxide, which binds to hemoglobin in red blood cells. This prevents the hemoglobin from binding to oxygen, thus preventing the transfer of oxygen in sufficient quantities to the various tissues. This explains the negative effect of smoking
The central nervous system, the heart muscle, and the blood vessels. Another dangerous substance in tobacco smoke is nicotine, which is considered to be a cancer of the highest degree of malignancy, and also causes blood vessel contraction, which has a negative effect on the coronary blood vessels in the heart and on the blood vessels in the brain. This substance causes addiction, so it is difficult to quit smoking.

Tobacco smoke particles can enter the body through direct smoke, or by passive smoking, ie inhalation of smoke rising from the burning end of the cigarette by non-smokers, but found in a smoker’s environment. Some believe that passive smoking can be more dangerous than active smoking, because the smoke from the burning end of the cigarette contains a higher concentration of dangerous ingredients than the inhaled smoke. Passive smoking causes people to have allergies in the airways and eyes, and increases the incidence of malignant diseases. It was found that lung cancer is more common not only in active smokers, but also in passive smokers. Passive smoking is a significant cause of fatal heart disease in both adults and children.

The toxicity of passive smoking to the cardiovascular system is varied, and is caused by various components in cigarette smoke. Passive smoking is particularly severe in relation to children who live with smoking parents. It was found that the chances of a child becoming a smoking mother due to lung problems were 70% higher than that of a child who did not smoke. It is also found that in children for parents who smoke, smoking is a very common phenomenon, if not the most common one.
