Can e-cigarettes quit smoking? E-cigarettes have no second-hand smoke? Throw it away quickly, it is making children addicted to cigarettes.

Verification expert: @ Yes, Dr. Li Gang | Attending physician of respiratory department of tertiary hospital.

On May 26th, the Health and Health Commission and the WHO Representative Office in China jointly released the report "Health Hazards of Smoking in China 2020".

The report shows that at present, the number of smokers in China exceeds 300 million, and the smoking rate of people aged 15 and above is 26.6%, among which the smoking rate of men is as high as 50.5%. Tobacco kills/kloc-0 million people every year. More than 740 million people are in a sub-health state because of secondhand smoke.

In addition to macro data, this report also lists the relationship between smoking and second-hand smoke and four major chronic diseases, and clearly points out for the first time that e-cigarettes are harmful to health.

Speaking of e-cigarettes, you must be familiar with them. The discussion about it has never stopped in recent years, and some e-cigarette lovers claim that,

But are all these statements true? If it is true, then why do the Health and Health Commission and WHO oppose it? Today is the 34th World No Tobacco Day. I want to talk to you about e-cigarettes.

In some ways, maybe.

The electronic cigarette we are talking about, in fact, is also called electronic nicotine release system, which is a new type of tobacco product that has developed very rapidly in recent years. E-cigarettes are generally composed of a host with batteries and a heating atomizer.

The main working principle of e-cigarette is to atomize the smoke liquid of e-cigarette into steam for human body to inhale through electric energy-driven heating. The components of e-cigarette liquid are simple: nicotine, propylene glycol, plant glycerin and natural spices.

The user activates the atomizer by inhaling the cigarette rod, and the atomizer heats the cigarette oil to form steam, thus achieving the effect of imitating the real cigarette smoke.

Compared with traditional cigarettes, the biggest advantage of e-cigarettes is that they don't need to be lit. Therefore, during the use of e-cigarettes, tar and carbon monoxide harmful to human body will not be generated.

From this perspective, e-cigarettes are indeed healthier than traditional cigarettes, which has become the core selling point of e-cigarettes.

In addition, because there is no open flame, the fire caused by smoking is also greatly reduced.

However, this does not mean that e-cigarettes are healthy, and e-cigarettes may be more terrible than traditional tobacco.

Wrong, maybe e-cigarettes are more harmful.

E-cigarettes have no tar and carbon monoxide harmful to human body. But e-cigarettes also contain nicotine, propylene glycol and glycerol, which is harmful to human body.

Although the physiological toxicity of these three chemicals is relatively low, they will still react under high temperature evaporation, and even produce some toxic chemicals, such as formaldehyde and acrolein, which will do some harm to the lungs.

From 20 19 to September 17, the US Centers for Disease Control and Prevention launched an emergency investigation to determine the relationship between e-cigarette use and lung injury and death.

Up to 20 19, 12 and 10, the United States has reported more than 2,409 hospitalized cases and 52 confirmed deaths.

More dangerously, in order to obtain greater economic benefits, some illegal businesses will illegally add addictive substances such as synthetic cannabinoids to e-cigarettes.

On May 14, according to CCTV news channel, Liaocheng police in Shandong Province cracked a case of illegally adding synthetic cannabinoids.

Now that we have mentioned addiction, let's talk about nicotine. Nicotine, commonly known as nicotine, is an important component of tobacco.

Studies have shown that nicotine can make people addicted or dependent. Repeated use of nicotine can also increase heart rate, raise blood pressure and reduce appetite. Large doses of nicotine can cause vomiting and nausea, and in severe cases people will die.

Both traditional cigarettes and electronic cigarettes contain nicotine. As e-cigarette manufacturers say, using small doses of nicotine will not have a negative impact on the body. But at least it can be addictive and dependent.

Therefore, no matter from the point of view of physical injury or addiction, e-cigarettes are not harmless.

There are the same ones.

Smokers will release harmful gases into the air during smoking. Non-smokers will suffer greater health threats after breathing the air polluted by second-hand smoke.

Some people say that e-cigarettes don't need to be lit, there is no tar and carbon monoxide, and there will be no second-hand smoke harmful to human body. However, this is also a pseudo-scientific view.

E-cigarettes mainly emit water vapor, which is not the smoke produced by combustion in the traditional sense, but it also brings second-hand smoke and third-hand smoke.

This is mainly related to the composition of e-cigarettes, which produce steam through atomizer, including harmful particles, propylene glycol, volatile organic compounds, heavy metals, nicotine and so on.

These vapors are actually an aerosol, which can stably disperse small particles of liquid or solid suspended in gas. These particles are usually below 1 micron and can be suspended in the air for a long time, so they will also bring harm to second-hand smoke.

When people use e-cigarettes, in fact, nicotine, acetaldehyde, formaldehyde and other harmful substances in the air will also increase significantly, which will also endanger the health of other indoor members.

Compared with smokeless fresh air, the second-hand aerosol generated by smoking e-cigarettes can make the value of PM 1.0 higher by 14-40 times, and the value of PM2.5 higher by 6-86 times.

Maybe not.

For smokers, quitting smoking is actually nicotine, and the most difficult thing is to resist nicotine withdrawal reaction.

People who smoke all the year round may have different degrees of discomfort after suddenly quitting smoking, such as irritability, dizziness, headache, insomnia and anxiety, inattention, coughing and sweating, decreased heart rate, increased appetite or weight gain, which will directly lead to relapse.

So from this perspective, e-cigarettes containing nicotine can't help to quit smoking.

In 20 15, the British Ministry of Health released a report that e-cigarettes have helped 20,000 smokers quit smoking every year. However, 95% of the data sources in this report are accused by some scholars of insufficient evidence or conflicts of interest, so they cannot be accepted.

In fact, there is no evidence that e-cigarettes help to quit smoking. On the contrary, after a large number of smokers use e-cigarettes, the consequences of dual use of cigarettes and e-cigarettes appear.

E-cigarettes only reduce the consumption of cigarettes, but increase nicotine dependence and increase the difficulty of quitting smoking.

20 19, 1 June, a paper was published in New England Medicine, one of the four major medical journals in the world. The researchers compared the effects of nicotine withdrawal therapy and e-cigarette, and finally found that 18% of people in the e-cigarette group quit traditional tobacco, while nicotine withdrawal therapy only helped 9.9% of people.

But after 52 weeks, 80% people are still using e-cigarettes, while only 9% people are still using nicotine withdrawal therapy. This shows that although e-cigarettes make people quit smoking, they will turn to e-cigarettes for a long time.

The original intention of designing e-cigarettes is to help people quit smoking and reduce the harm of cigarettes. But the result may run counter to the original intention. Instead of helping to quit smoking, it makes more teenagers addicted to cigarettes prematurely.

E-cigarettes have popular cultural attributes, electronic attributes and spice additives, which are particularly easy to attract teenagers. Take Hong Kong, the birthplace of Asian pop culture, as an example. According to the research of the University of Hong Kong, the use rate of e-cigarettes among young people under 25 in Hong Kong is as high as 85.9%.

Among them, 5 1.3% of teenagers said that curiosity was the main reason for using new tobacco products such as e-cigarettes, followed by friends (37.3%) and hope to use new tobacco to quit smoking or reduce cigarette consumption (2 1.6%). Respondents generally believe that new types of tobacco, such as e-cigarettes, are healthy and help to quit smoking.

But the end result is just the opposite. Not only did they not get rid of traditional cigarettes, but they also became consumers of new tobacco products.

Let's call it a day. I hope you can have a clearer and more complete understanding of electronic cigarettes. It may make you say goodbye to traditional tobacco, but it will also make you more dependent on nicotine. It will also make you and your family suffer from various respiratory diseases.

If you choose e-cigarettes to quit smoking, you don't have to climb out of the pit of cigarettes carefully and fall into the pit of e-cigarettes. If you really think about the health of yourself and your family, you might as well give up smoking completely.

Friends with poor self-control can go to the smoking cessation clinic of a professional hospital, and the doctor will help you bid farewell to smoking addiction with professional medical intervention and psychological counseling.
