Cigarette smoking is believed by most research workers in this field to be an important factor in the development of cancer of the lungs and the throat and is believed to be related to cancer of the bladder(膀胱) and the oral cavity(口腔). Male cigarette smokers have a higher death rate from heart disease than non-smoking males.
Female smokers are thought to be less affected be cause they do not breathe in the smoke so deeply. The majority of physicians and researchers consider these relationships proved to their satisfaction and say. "Give up smoking. If you don't smoke, don't start". Some competent physicians and research workers - though their dwindling(减小) even further-are less sure of the effect of cigarette smoking on health. They consider the increase in respiratory (呼吸的) diseases and various forms of cancer may possibly be explained by other factors in the complex human environment - atmospheric pollution, increased nervous stress, chemical substances in processed food, or Chemical pesticides that are now being used by farmers in vast Quantities to destroy insects and small animals. Smokers who develop cancer or lung diseases, they say, may also, by coincidence, live in industrial areas, or eat more canned food. Gradually, however, research is isolating all other possible factors and proving them to be statistically irrelevant. While all tobacco smoking affects life expectancy and health, cigarette smoking appears to have a much greater effect than cigar or pipe smoking. However, nicotine(尼古丁)consumption is not diminished by the latter forms, and current research Indicates relationship between all forms of smoking and cancer of the mouth and throat. Filters and low tar(焦油) tobacco are claimed to made smoking to some extent safer, but they can only marginally reduce ,not eliminate, the hazards.
