There's less smoking now. It's OK to have one occasionally? "I used to smoke three packs of cigarettes a day, but now I smoke one pack of cigarettes three days a day. It should be OK to smoke so much less, right?" I believe this is the inner monologue of many smokers. However, is that really the case? Mistake: Once in a while, smoking is not harmful to human health. Some smokers may say, "I know smoking is harmful, but I just can't quit. Then I should smoke less, and the harm will be small." This idea is totally wrong! Since smoking is harmful, even a puff of smoke can cause harm to the body. The smoke contains at least 69 carcinogens. For example, if you don't want to take a sip of toxic milk containing a small amount of trichlorocyanulamine, why can you take a cigarette occasionally? Mistake 2: It is safer to smoke low tar cigarettes. In recent years, tobacco companies have introduced "low tar cigarettes". They claim that "low tar cigarettes" can reduce the amount of tar consumed by the human body, thereby reducing the harm of smoking to health. But the fact is that the so-called "low tar cigarettes" are just a means of propaganda for tobacco traders. The purpose is to improve the attractiveness of cigarettes, so as to induce smokers to continue smoking or weaken their willingness to quit smoking. In order to determine whether the harm of "low tar cigarette" is less than that of ordinary cigarettes, medical experts evaluate it by measuring the content of metabolites of nicotine and other harmful ingredients inhaled into the body. The results showed that the content of harmful components in tobacco smoke of "low tar cigarette" smokers was not lower than that of ordinary cigarette smokers. In addition, the American Cancer Society has also confirmed through research that smoking low tar cigarettes does not reduce the risk of smokers dying of lung cancer. Mistake: Three filters can reduce the harm of tobacco. Most cigarettes are equipped with filters. It is generally believed that the installation of filters can filter out most of the harmful components in the smoke and minimize the harm of smoking to health. But can filter cigarettes really reduce the harm of smoking to health? Experts point out that the tar content of cigarettes is measured by smoking machine to simulate the smoking behavior of smokers. Cigarettes equipped with filter tips do show a decrease in tar content when tar content is measured. But the actual situation of smokers smoking is completely different from that of machines... The tar content measured by machine smoking method cannot reflect the tar intake of smokers in the actual smoking process. In addition, smokers have "compensation behavior" when smoking filter tip cigarettes. The filter tip of the cigarette has one to several circles of air holes. The function of these vents is that when smoking cigarettes, some air can enter the filter tip from the vents, thus reducing the concentration of smoke inhaled. When smokers smoke "low tar cigarettes", they often cover the air holes on the filter tip with their fingers and lips, making them ineffective, and the smoke concentration inhaled does not decrease. In addition, in order to obtain enough nicotine to alleviate the addiction, smokers tend to inhale more tobacco smoke per mouth, smoke more cigarettes and smoke more times per cigarette. These behaviors did not reduce the amount of harmful substances such as tar that smokers actually inhaled. (Outlook New Times)
