HEALTH: Smoke and disease

Smokers are addicted to nicotine. Although it seems an obvious concept, people ignore the word “addiction” or the smoke that cigarettes emit, so it is urgent to re-educate the entire population and more to smokers who assure that they can stop smoking when they do so.

Smoking tobacco is the most common way to self-administer nicotine through the mouth. Although addictiveness is dictated mainly by the effect of nicotine, the rest of the diseases caused by smoking are derived from the rest of the substances in tobacco smoke.

The composition of cigarette smoke depends on the type of tobacco, the curing method, the length of the cigarette, the combustion temperature, the characteristics of the paper, the presence and effectiveness of the filter, and the additives added to the tobacco. Currently, more than four thousand components have been identified in cigarette smoke.

However, unlike all other products for human consumption, none are on cigarette packaging.

This smoke comprises two phases that then form the aerosol: one gaseous and the other in particles. Most of the smoke comes from the mouthpiece during spraying as the smoker exhales.

Meanwhile, less is generated between sprays from the glowing cone and the voice.

According to their medical importance and regardless of whether they are in the gaseous or particulate phase, the components of cigarette aerosol are classified as:

1. Carcinogens: substances that, by themselves, are directly responsible for cancer.

2. Co-carcinogens: substances that, only in the presence of carcinogens, can cause cancer.

3. Ciliotoxins and lung irritants: compounds that generate an allergic and irritant response and are responsible for stagnation secretions.

4. Nicotine: responsible for addictiveness.

5. Radioactive metals, carbon monoxide, and other toxic compounds.

The burning point of tobacco in a cigarette varies between 300 ° C and 9,000 ° C between the mouthpiece and the lit cone. Some substances break down, and others recombine to generate other compounds.

Also, some substances pass unmodified from tobacco to smoke. In contrast, others seep into unburned smoking as the smoke passes through the rest of the cigarette.

However, it should be mentioned that only 15% of the composition of tobacco smoke is of fundamental medical importance since they are associated with the appearance of certain diseases and cancers.
