It is as harmful as cigarettes.
Add some information to it.
Smoking cigars is no safer than smoking. A report by the National Cancer Institute in the United States pointed out that smoking cigars every day can cause various cancer diseases, such as oral cancer, tongue cancer, laryngeal cancer, esophageal cancer and lung cancer, as well as coronary heart disease and other lung diseases. There is evidence that smoking cigars has a great relationship with pancreatic cancer. At present, the cure rate of lung cancer, esophageal cancer and pancreatic cancer is very low. Cigars, like smoking, contain many harmful substances, such as cadmium, nicotine, ammonia and carbon monoxide, which can cause cancer. The ammonia content in cigar smoke is 20 times that of cigarettes, while the cadmium content in cigar smoke is 5 to 10 times that of cigarettes. The reason is that the fermentation process of making cigars will produce higher concentration of nitrate. Because the paper used to roll cigars is airtight, the burning process of smoking cigars can not completely burn cigars, thus producing more harmful substances.
It is also reported that a cigar contains a considerable amount of nicotine in a pack of cigarettes, and the incidence of oral cancer and throat cancer caused by smoking cigars is eight to ten times that of non-smoking. That's because when a cigar burns, it will produce alkaline gas, which will accelerate the absorption of nicotine by oral mucosa. According to the data of Taiwan Province Dongshi Foundation, the average nicotine content of a cigarette is 8.4 mg, while that of a cigar is 10 to 44 mg. Smoking a cigar is equivalent to smoking a whole pack of cigarettes (and the price is the same).
Although the habit of smoking cigarettes and cigars is different, cigar smokers rarely inhale cigarettes into their lungs, and most cigar smokers don't smoke cigars every day. However, studies have found that inhaling smoke into the lungs during smoking will increase the risk of illness; Therefore, cigar smokers generally have a lower risk of cancer than cigarette smokers. However, because cigars contain more harmful substances than cigarettes, and cigars dissipate longer than cigarettes, the risk of passive smoking cigars (second-hand smoke) is higher than cigarettes. Therefore, non-smokers should stay away from cigar environment.
Ma Jin said, "Cigar smokers have never had sex." This shows that cigar smokers have a philosophical positive attitude towards life, an open mind and a tenacious will (a bit exaggerated, but not unreasonable). Churchill's longevity of 9 1 year provides the best proof for this statement. In addition, it has been reported that 1 roast chicken leg = 60 cigarettes is toxic. Will there be fewer people eating roast chicken legs?
God bless those who are happy.
