With the gradual improvement of people's quality of life, people pay more attention to their health, coupled with the continuous strengthening of tobacco control, non-combustible tar-free electronic cigarettes suddenly caught fire. However, consumers have different views on e-cigarette products in the market. Some people say that e-cigarettes are deceptive, while others say that e-cigarettes are very effective and can help them quit smoking quickly. So is e-cigarette really healthy?

What changes have been made to the body by smoking e-cigarettes?

I am 30 years old and have been smoking 10 years. I pack about half a pack of cigarettes a day at present. 1 1 I thought about quitting smoking years ago. At that time, I bought an electronic cigarette from Kangcheng, just like cigarettes. The white part is a rechargeable battery, the filter tip part is replaceable, and there is cigarette oil in it. I feel chest tightness after smoking for about two or three months.

In the next 20 years, I bought York e-cigarette, which was better than the previous e-cigarette and there were many flavors to choose from. However, due to the large number of flavors, the mediation of these flavors is bound to be inseparable from chemicals such as flavors, and because of the low tar content and high smoking frequency of cigarettes, they are no longer used.

So I think the harm of e-cigarettes is still greater than that of cigarettes. Quitting smoking actually depends on your own perseverance, just like the way to get rid of one interest is to love another. Personally, I think the probability of e-cigarettes quitting smoking is too low.

So why does e-cigarette cause this situation?

1. E-cigarettes still contain nicotine, which is as dependent as ordinary cigarettes and has a direct impact on the cardiovascular system of the human body. The chemical substances that produce the fragrance of e-cigarettes have also been proved to be cytotoxic. Therefore, smoking e-cigarettes is not much safer than smoking cigarettes, which is not fully supported in theory.

2. The second-hand smoke of e-cigarettes is related to the gas exhaled by users, which contains harmful substances such as nicotine and fine particulate pollutants PM2.5. Although the second-hand smoke concentration of e-cigarettes is much lower than that of traditional cigarettes, it is indeed harmful.

3. It is generally believed in the market that e-cigarettes can be used as an auxiliary means for smokers to quit smoking, but they are not included in the clinical guidelines for quitting smoking, and clinicians will not advise smokers to use e-cigarettes to quit smoking.

4. The "safety" and "health" promoted by e-cigarette manufacturers are actually misleading consumers, and these concepts are not supported by enough scientific basis. Even international authorities are cautious about e-cigarettes.
