In the world there are many types of cigarettes. Smokers in many countries prefer cigarettes with different strength and with a variety of flavors and aroma characteristics.
In the production of cigarettes, as a rule, are used different varieties of tobacco grown in different countries, and mixed in a certain way in order to meet the diverse tastes of smokers. On the type of aroma bags depend flavor and strength of cigarettes. In the manufacture of cigarette are used three main types of tobacco: "Virginia," or heat-cured tobacco, "Berkeley" and oriental blend. Preferences of consumers of cigarettes in different countries are different. For example, in Britain the majority of smokers prefer cigarettes so-called English-bags, which consist mainly of tobacco, "Virginia," while in the U.S., many American consumers buy cigarettes, which include all three above-mentioned types of tobaccos, like Marlboro cigarettes.
In the production of cigarettes, a special breathable paper, which affects the stability of the formation of ash and the level of smoking components entering the smoker's lungs. Paper with higher porosity, ie air permeability, is used in the development of cigarettes with low tar.
The filter is designed to reduce the amount of smoke and some of its components to set into the smoker's body. Most filters are made of organic fiber - cellulose. Cellulose does not have its own flavor and strong enough to maintain its shape. Along with other design elements of cigarettes, such as ventilation, use of filters with different filter efficiency can reach different levels of tar and nicotine, and eventually - castle different taste and flavor intensity of tobacco smoke.
Cigarette is ventilated in order to reduce the level of smoking components, primarily tar, nicotine and carbon monoxide. All cheap cigarettes are ventilated by natural air permeability of cigarette paper; in addition, many cigarettes are ventilated through perforated filter rim. In the process of tightening the air coming through the perforations, is mixed with the smoke coming from the zone of smoldering cigarettes. Ventilation is the primary filter and binding characteristics of cigarettes with low tar.
Tobacco smoke is perhaps one of the toughest and most active of the studied compounds in the world. Like many other natural substances, tobacco contains thousands of components (currently identified about 2500). In the process of burning tobacco, depending on temperature and oxygen concentration is formed around 4000 smoking substances. The concentration of most of them is insignificantly small.
Mainstream smoke - the smoke that enters the smoker's respiratory system when it is tightened, and a side stream smoke - smoke that is released from the smoldering end of cigarettes.
The complex structure of cigarette smoke is one of the difficulties faced by researchers when trying to determine what components and substances of tobacco smoke have an impact on the health of the smoker, causing certain diseases associated with smoking.
