Tobacco reduces coke, harm does not decrease but increases
Fact 1. Low-tar cigarettes will produce compensatory smoking Wu Yiqun introduced to a reporter from China News Weekly.com that the nicotine in the tar decreases in an equal proportion, but addiction is caused by nicotine, and when the tar decreases, there will be several situations for smokers: smokers smoke more , smoked deeper, and smoked more frequently. After the amount of tar is reduced, the smokers will adopt "compensatory behavior" to maintain the concentration of nicotine in the blood, they will inhale deeper and more, and with the increase of the number and amount of smoking, the other harmful substances in the inhaled tobacco will also increase . The reporter inquired about the information and found that, in fact, the world has already reached a conclusion, and it has been determined that low tar cannot be low in harm. For example, in 2012, the US court ruled that tobacco companies should apologize to the American public in five ways, saying that "low tar and low harm" deceived the public. Truth 2. The actual tar intake is 3 times the labelled amount Wu Yiqun said that in the 1950s, Western cigarette companies introduced "low-tar", "light" cigarettes, whose name came from the lower tar and nicotine delivered when smoking machines were tested. "But it was the tobacconists who deliberately designed these cigarettes to deliver lower tar when tested, knowing fully that these machine-tested metrics were not an accurate reflection of the tar and nicotine actually received by the smoker." Inside Marlboro, 1977 The data also showed that the actual tar intake of smokers was three times higher than the machine test data. Fact 3: There may be more carcinogens in low char cigarettes Dr. Gan Quan, senior program officer of the International Federation of Anti-Tuberculosis and Lung Diseases, has personally conducted relevant experiments. He analyzed the urine of Chinese adult male smokers and compared nicotine by-products and carcinogens in tobacco smoke puffed by smokers of cigarettes with different tar levels. The results showed that the levels of nicotine by-products and carcinogens found in the smokers' urine did not differ according to the tar content of the cigarettes they smoked. In fact, the levels of one of the harmful carcinogens (nitrosamine metabolites) increased as the tar levels of the cigarettes smoked decreased. There are more than 7,000 compounds in tobacco smoke, hundreds of which are toxic and at least 69 carcinogens. Wu Yiqun also analyzed to the reporter of China News Weekly, "Because the nitrosamines unique to tobacco are strong carcinogens, the tar is low, and the content of some compounds in tar will also be low, but the nitrosamines unique to tobacco are also low. Amines are elevated, which is a negative correlation." So lower tar doesn't mean lower other carcinogens. Toxicological studies have proved that some strong carcinogens in tar are not reduced when the tar content decreases, such as nitrosamines and condensed aromatic hydrocarbons. Reducing the tar content of cigarettes cannot reduce the harm of tobacco to health. Previous media reports have also proved this statement, cigarettes contain more than 4,000 chemicals, at least 69 of which may cause cancer. Among them, the content of carcinogens such as nitrosamines and condensed aromatic hydrocarbons will not decrease with the decrease of tar content.
