THE passive smoker one day is a miracle. Gloria Fuertes. MORE than five CENTURIES of SUBJECTION to the whole tobacco smoke began more than five centuries with a friendly gift from the Indians to the discoverers. Although we record that Rodrigo de Jerez it was who brought tobacco to Spain. The Spanish soon made use of those limp and dry leaves, as described Cristobal Colon in his diary on board to the Nicotiana tabacum, by the kind of drunkenness that produced the inhalation of its smoke. After more than five centuries tobacco consumption is regarded as one of the greatest sanitary pests, causing direct death of millions of people around the world.
Smoking is the most important factor of premature death to prevent Western countries, making him responsible for 15 percent of premature deaths. Now considered almost the third part, 30 percent of all cancer deaths are attributable in greater or lesser extent, tobacco and also he is considered responsible for 75 percent of cases of chronic bronchitis and 25 percent of the heart disease. While it is true that Spaniards have been few years not smoking, it seems that the first fruits are already looming, observing a downward trend in tobacco consumption. However, Spain is still next to Cyprus and Greece, a leadership among the countries of the European Union with greater number of smokers in the world ranking who lead, by this order, Cyprus, Greece, Cuba, Canada, United States and Spain with an annual consumption per person between 2,500 and 3,000 cigarettes. Among the nearly 4,000 compounds known are present in tobacco smoke, a large part of them has potential mutagen and carcinogen. Today is fully demonstrated that certain substances, such as nicotine or tar and carbon monoxide are hazardous to health. Irritating and carcinogenic tar compounds are responsible for respiratory pathology of smokers, nicotine and carbon monoxide are responsible for the increased cardiovascular risk.
