Is e-cigarette harmful?

Electronic cigarettes, also known as virtual cigarettes, electronic steam generators and electronic atomizers, are mainly used to replace cigarettes and quit smoking. In developed countries in Europe and America, they play the role of a fashion plaything. It has a variety of appearances and hundreds of flavors, and it can also smoke, smell and feel like a cigarette. An electronic cigarette is a cigarette-imitating device consisting of a lithium battery, an atomizer and a cigarette bomb. The liquid containing nicotine is vaporized through the atomizer and inhaled directly, but no smoke is generated in the process. E-cigarettes have no tar, suspended particles and other harmful components in cigarettes, and manufacturers also believe that e-cigarettes have no diffuse or lingering second-hand smoke. Some countries believe that e-cigarettes must meet the drug standards before they can be sold as smoking cessation drugs. It should be noted that e-cigarettes do not have the effect of clearing lung toxicity, and the discussion that e-cigarettes can clear lung toxicity is false and illegal propaganda. In developed countries in Europe and America, e-cigarettes are very popular with smokers and become the best choice for replacing cigarettes in current fashion. Some studies have pointed out that 85% of smokers do not belong to the real sense of addiction, but actually they are just a kind of addiction in behavior habits. View details > > \xd\ e-cigarettes \xd\ In recent years, with the non-stop anti-smoking campaign in various countries around the world, e-cigarettes came into being and became popular. It is estimated that there are about 1 million smokers in the United States and Europe who regularly consume electronic tobacco products. This electronic atomizer, which imitates cigarettes and is easy to carry, was invented and patented by China people. E-cigarette makes propylene glycol or glycerol into fog, so that it can be directly inhaled into human body, which looks like smoking. \xd\ However, in recent years, scientific research institutions have continuously proved through experiments that e-cigarettes are harmful to human body, even more harmful than traditional cigarettes, and called on the government to take control measures. \xd\ Structure and basic principle \xd\ Structure of electronic cigarette \xd\ The appearance of electronic cigarette is similar to that of traditional cigarette, but the internal structure is very different, which is generally composed of battery rod, atomizer and smoke bomb. The atomizer is powered by the battery pole, which can turn the liquid nicotine in the cigarette bomb into fog, so that the user has a feeling similar to smoking when smoking. \xd\ The nicotine content in cigarette bombs is not static, and it is divided into high, medium and low concentrations. Nicotine is the main cause of smoking addiction, which will make smokers feel happy and naturally addicted. Sellers package e-cigarettes into pollution-free smoking cessation products, the principle of which is to gradually reduce the amount of nicotine in cigarette bombs, help smokers get rid of nicotine dependence and realize smoking cessation. \xd\ The harm of e-cigarettes \xd\ causes lung contraction and inflammation \ xd \ xd \ The harm of e-cigarettes is not less than that of traditional cigarettes \ xd \xd\212, with the financial support of the Greek Cancer Society, Konstantin Vadavas, the chief researcher of the Global Tobacco Control Center of the School of Public Health of Harvard University, and his colleagues, conducted a research on 3. \xd\ Researchers found that five minutes after smoking e-cigarettes, their lungs showed signs of contraction, and combined with other breath tests, they also found inflammatory symptoms. This is the first time that there is evidence that just using an electronic cigarette can produce such a strong stimulus to the respiratory system. \xd\ It is not clear whether this short-term lung reaction will cause long-term health effects, such as emphysema and other lung diseases. However, the researchers stressed that if it takes only a few minutes to cause respiratory changes, the possible consequences of repeated use of e-cigarettes for a long time will have to be taken seriously. \xd\ High nicotine content is easy to cause cancer \xd\ Dr. Elizabeth Porter, director of the German Federal Health Education Center, said that e-cigarette manufacturers added a large amount of propylene glycol as a humidifier in order to evaporate liquid nicotine from cigarette bombs and make them smoke. Propylene glycol can account for up to 9% of the liquid content in the smoke bomb. This substance is easy to irritate the respiratory tract, and then causes some acute symptoms, which may be more harmful to health than traditional cigarettes. \xd\ In addition, a French study shows that the use of electronic cigarettes can also lead to cancer. According to the data of French National Institute of Consumption, some electronic cigarettes contain high nicotine content, and some electronic cigarettes contain carcinogens that are not less harmful to human health than ordinary cigarettes. Therefore, electronic cigarettes can also cause harm to the body, which can cause cancer just like ordinary cigarettes. \xd\ At the same time, because the electronic cigarette device heats up too fast, a highly toxic molecule called acrolein will be produced in the process. Inhalation of acrolein may damage the respiratory tract, resulting in pharyngolaryngitis, chest oppression and bronchitis; Inhalation can cause pneumonia, pulmonary edema, shock, nephritis and heart failure. \xd\ Liquid nicotine in electronic cigarettes may be fatal to children. However, the researchers pointed out that there is no reason to ban the use of electronic cigarettes for the time being, and there are no special measures to protect children from the harm of electronic cigarettes. \ xd \xd\29, the US Food and Drug Administration (FDA) analyzed the products of several e-cigarette manufacturers, and found that in these e-cigarettes, besides ethanol and glycerol, there were trace amounts of carcinogenic nitrosamines and other potentially harmful substances. \ xd \ xd \ WHO does not recognize its efficacy in quitting smoking \ xd \ xd \ The World Health Organization made a public statement on "e-cigarette" in September 28, saying that there is no scientific evidence to prove that e-cigarette is a safe and effective tool for quitting smoking. WHO has never considered electronic cigarettes as a legal nicotine substitute to help smokers quit smoking. \xd\ Attitudes of countries towards e-cigarettes \ xd \ xd \ Total ban \ xd \ At present, e-cigarettes have been banned in Canada, Norway, Switzerland, Turkey, the United States, Australia, Brazil, Argentina and other countries. \ xd \ xd \ Their health departments believe that e-cigarettes are not as healthy and harmless as advertised by manufacturers, and they contain a certain amount of carcinogens and nicotine, so the sale and consumption should be prohibited. The CDC of American medical and health institutions reminds that among young people, including those who never smoke, e-cigarettes should be accurately positioned and prohibited from being sold to minors. \xd\ Relative prohibition \xd\ When the European Commission revised the EU Tobacco Products Directive, it was proposed that e-cigarettes should be classified as drugs, just like nicotine chewing gum and plaster that help smokers quit smoking, and the nicotine content of e-cigarettes approved as medical products should be restricted. \xd\\xd\ Hanover, Germany, has issued regulations prohibiting "smoking" electronic cigarettes in public offices and cars, while Italy and France prohibit the sale of electronic cigarettes to minors.
