Smoking Is A Problem Of Smoking

Smoking soon spread to other areas and today is widely practiced around the world despite medical, social, and religious arguments against it.

Smoking , the act of inhaling and exhaling the fumes of burning plant material. A variety of plant materials are smoked, including marijuana and hashish , but the act is most commonly associated with tobacco as smoked in a cigarette , cigar , or pipe. Tobacco contains nicotine , an alkaloid that is addictive and can have both stimulating and tranquilizing psychoactive effects. The smoking of tobacco, long practiced by American Indians , was introduced to Europe by Christopher Columbus and other explorers.

Smoking soon spread to other areas and today is widely practiced around the world despite medical, social, and religious arguments against it. At the dawn of the 20th century, the most common tobacco products were cigars, pipe tobacco, and chewing tobacco.

The mass production of cigarettes was in its infancy, although cigarette smoking was beginning to increase dramatically. Moreover, because of the rapid increase in smoking in developing countries in the late 20th century, the number of smoking-related deaths per year was projected to rise rapidly in the 21st century.

For example, the World Health Organization WHO estimated that in the late s there were approximately four million tobacco-caused deaths per year worldwide.

This estimate was increased to approximately five million in and six million in and was expected to reach eight million per year by An estimated 80 percent of those deaths were projected to occur in developing countries. Indeed, although tobacco use was declining in many countries of western Europe and North America and in Australia, it continued to increase in countries of Asia, Africa, and South America. The primary cause of the escalation in the number of deaths and incidents of disease from tobacco is the large increase in cigarette smoking during the 20th century.

Nonetheless, all tobacco products are toxic and addictive. In some regions of the world, the use of smokeless tobacco products is a major health concern. The smoke produced when tobacco and these additives are burned consists of more than 4, chemical compounds. Many of these compounds are highly toxic, and they have diverse effects on health. The primary constituents of tobacco smoke are nicotine , tar the particulate residue from combustion , and gases such as carbon dioxide and carbon monoxide.

Although nicotine can be poisonous at very high dosages, its toxic effect as a component of tobacco smoke is generally considered modest compared with that of many other toxins in the smoke. The main health effect of nicotine is its addictiveness.

Carbon monoxide has profound, immediate health effects. It passes easily from the lungs into the bloodstream, where it binds to hemoglobin , the molecule in red blood cells that is responsible for the transfer of oxygen in the body. Carbon monoxide displaces oxygen on the hemoglobin molecule and is removed only slowly. Therefore, smokers frequently accumulate high levels of carbon monoxide, which starves the body of oxygen and puts an enormous strain on the entire cardiovascular system.

The harmful effects of smoking are not limited to the smoker. The toxic components of tobacco smoke are found not only in the smoke that the smoker inhales but also in environmental tobacco smoke, or secondhand smoke—that is, the smoke exhaled by the smoker mainstream smoke and the smoke that rises directly from the smoldering tobacco sidestream smoke.

Nonsmokers who are routinely exposed to environmental tobacco smoke are at increased risk for some of the same diseases that afflict smokers, including lung cancer and cardiovascular disease. Clean-air laws that prohibit cigarette smoking are becoming widespread.

In the s and s, such laws typically required that nonsmoking areas be established in restaurants and workplaces. However, the finding that toxins in environmental smoke could easily diffuse across large spaces led to much stronger bans. Since many cities, states, and regions worldwide, including New York City in , Scotland in , Nairobi in , and Chicago in , have implemented complete smoking bans in restaurants, taverns , and enclosed workplaces.

A ban introduced in in China , which was home to one-third of the global smoking population , barred smoking in hotels, restaurants, and other indoor public spaces the ban did not include smoking in workplaces, nor did it specify penalties. In addition, entire countries have implemented smoking bans in workplaces or restaurants or, in some cases, in all public areas, including Ireland , Norway , and New Zealand in and France and India in In Bhutan became the first country to ban both smoking in public places and the sale of tobacco products.
