Low-tar cigarettes is more harmful to health

Centers for Disease Control Tobacco Control Office of the Deputy Director Professor Jiang Yuan and China's Capital University of Medical Director of the Center of lung cancer treatment, Professor Zhi Xiuyi a guest expert interview, the talk to netizens for the health hazards of smoking. Many smokers believe that low-tar cigarettes is relatively safe, the two experts have severely criticized this view, and through the experimental data and clinical experience suggests that low-tar cigarettes does not reduce the harm caused by smoking on the body, in the under certain circumstances, it may increase the total amount of smokers smoking.
Professor Jiang Yuan Speaking: tobacco, there are more than 4000 kinds of substances, among which there is something called tar, tar also contains 56 kinds of compounds actually. Generally less than 7 mg ,7-called low-tar is the tar 15 mg, 15 mg or more is a high-tar. China from July 1, 2005 can no longer start selling for more than 15 milligrams of tar content of cigarettes. Most began a Chinese scholars have found to tar coated in rabbit ears would induce cancer. According to the research conclusions may be inferred the tar in cigarettes causes lung cancer, he proposed the concept of harm reduction of tar, so that the tar content of cigarettes marked down 60%.

It was generally believed that if you can not stop smoking, can smoke low-tar, and not so great for health hazards. However, the tar at the same time reducing the nicotine in cigarette smoke is declining, nicotine is addictive substances, can not let smokers fail to thrill, the amount of smoking may be more numerous. In addition, people think that smoking low-tar cigarette smoke is safe, but not easy to quit smoking.

In fact, there are many tobacco carcinogens, from the urine of smokers inside the pre-cancerous substances extracted point of view, smoking high-tar, medium tar and low tar level is the same, so carcinogenicity has not been reduced, several large population studies have found that people who smoke low-tar cancer risk did not decline.

Professor Zhi Xiuyi: Research shows that smoking low-tar cigarettes do not lower the risk of lung cancer risk, pumping medium-tar cigarettes and low tar content in cigarettes, people who died from lung cancer, there is no significant difference in the proportion. Tobacco harm reduction on the low-tar tobacco publicity is unfounded, unscientific and irresponsible. For the majority of smokers, the protection of health, the best way to prevent lung cancer from tobacco.

Reduce the tar content of tobacco Why did not reduce the dangers of tobacco? As the tobacco companies did not tell smokers smoke the correct grip position, in fact smokers are still subjected to the dangers of nicotine and tar, another addition to the tar in tobacco, there are a variety of other carcinogens.

Smokers and smokers the increase in the amount of the incorrect Nayan posture led to a low tar cigarettes did not reduce the main hazards. The so-called low-tar cigarettes is usually filtered through the lips of the side holes to achieve, in order to ensure the smooth side hole dilute the tar content in tobacco, but smokers are often the lateral holes covered by fingers or lips, filters to protect lips side of the hole the role of the lost. So, speaking for the majority of smokers, inhalation of tobacco tar in fact not been reduced.

In addition, smokers who smoke low-tar tobacco reform, the increase in the number of cigarettes smoked and smoking also contribute to the deepening intensity of low-tar tobacco health hazards of important reasons. When smokers choose low-tar cigarettes, rather than an ordinary cigarette, it is always a deeper every cigarette smoking, so that would be inhaling more nicotine and tobacco in the harmful substances.

Low-tar cigarettes, the tobacco companies under the banner of the name attracted a lot of smokers, our data show that low-tar tobacco advertising to 60% of smokers believe that low-tar cigarettes are harmless and healthy, so that 50% of smokers believe that low-tar tobacco can be to help them quit smoking more quickly. From a worldwide perspective, the low-tar tobacco production since the beginning of the last century on behalf of three to four decades has maintained a rising trend, this aspect is the success of the tobacco industry marketing strategy, it also exposed the health hazards of tobacco promotion of the dead.
