Is electronic cigarette harmful?

Question 1: Is e-cigarette harmful to health? How does it compare with the harm of smoking? In fact, e-cigarette is a kind of non-combustible e-cigarette, also called "atomized e-cigarette". It consists of a shell, a cigarette holder, a dust filter, a spice box, a light-emitting diode, a power supply and a cigarette cap. It does not burn, only contains purified nicotine, does not contain tar, does not contain chemicals that cause respiratory and cardiovascular diseases in ordinary cigarettes, and removes other carcinogens in ordinary cigarettes. Its efficacy is similar to that of ordinary cigarettes, which can refresh the mind, satisfy the craving, make smokers feel happy and relaxed, and at the same time have the function of quitting smoking. The essential difference between "electronic cigarette" and ordinary cigarette is that it contains no tar harmful to human body and no carcinogen; Do not burn, and do not produce harmful chemicals after burning; There is no harm to others and environmental pollution caused by "second-hand smoke"

Question 2: Why is electronic cigarette more harmful? The news now is really. You must have looked up a lot of information

Let me explain. This is just my own opinion.

The original title-"E-cigarettes may be more harmful than traditional cigarettes"

What do you mean maybe? As I said, e-cigarettes may be harmless at all.

The original text said-"According to the British" Daily Mail "report, an expert who studies electronic cigarettes said earlier that the manufacturer added a large amount of propylene glycol as a humidifier to evaporate the liquid nicotine in the cigarette bomb and make it smoke. The liquid content of propylene glycol in smoke bombs can account for up to 90%. " This substance is easy to breathe, and then causes some acute symptoms, which may be more harmful to health than traditional cigarettes. "

It's possible again. The person who wrote this article doesn't know. What can you do for our readers? Totally irresponsible.

What is propylene glycol? The US Food Safety Administration defines propylene glycol as basically harmless to human body. (own Baidu science popularization bar)

According to the original text, at present, e-cigarettes have been banned in Norway, Switzerland, Turkey, Canada, Australia, Brazil, Argentina and other countries.

Norway has not banned e-cigarettes. Norway asked to delete all the pictures of electronic cigarettes and the positive reports of products and accessories on its website. According to the new regulations, the illustrations of e-cigarettes can only be in black and white.

Switzerland does not ban e-cigarettes, but only smoking e-cigarettes in public transportation, and offenders will be fined 20 euros.

In Canada, only Vancouver intends to ban e-cigarettes. Note that the reason for the ban is that e-cigarettes are likely to become "entry-level cigarettes" for teenagers.

In Australia, e-cigarettes are not prohibited, but they are not allowed to be sold to minors. It is forbidden to sell e-cigarettes containing nicotine, because nicotine is a contraband in Australia.

Why does Turkey ban e-cigarettes? Because Turkey bans not only electronic cigarettes, but also real cigarettes. E-cigarettes are only carried by unlucky people.

Brazil and Argentina do ban the sale of e-cigarettes. Tobacco is a heavy tax and cigars are made in Brazil, you know.

It can be said that the person who wrote this article is completely making it up.

As for the experiment in Japan, it was conducted at 5V, and the experimental conditions were simply wrong.

Totally hand-beaten, so tired.

Question 3: Is e-cigarette harmful? The harm of e-cigarettes is there, but it is very small, much less harmful than ordinary cigarettes.

In fact, e-cigarette is a kind of non-combustible e-cigarette, also called "atomized e-cigarette". It consists of a shell, a cigarette holder, a dust filter, a spice box, a light-emitting diode, a power supply and a cigarette cap. It does not burn, only contains purified nicotine, does not contain tar, does not contain chemicals that cause respiratory and cardiovascular diseases in ordinary cigarettes, and removes other carcinogens in ordinary cigarettes. Its efficacy is similar to that of ordinary cigarettes, which can refresh the mind, satisfy the craving, make smokers feel happy and relaxed, and at the same time have the function of quitting smoking.

The essential difference between "electronic cigarette" and ordinary cigarette lies in:

Does not contain tar components harmful to human body, and does not contain carcinogens;

Do not burn, and do not produce harmful chemicals after burning;

There is no harm to others and environmental pollution caused by "second-hand smoke";

There is no fire hazard, and it can be used in places where smoking and fire are prohibited.

Non-toxic, non-combustible and pollution-free, it is a good substitute for cigarettes.

Question 4: Is e-cigarette really completely harmless? What is an electronic cigarette? E-cigarette is an electronic product. It has the same appearance as ordinary cigarettes and the same taste as cigarettes. It can also suck out cigarettes and taste like cigarettes. However, e-cigarette is not a real cigarette. It is composed of air induction switch, intelligent control circuit, intelligent chip, lithium-ion battery and other microelectronic high-tech devices. It is an effective product to replace cigarettes and help people quit smoking. Smoking is harmful to health. We all know that smoking is harmful to health. Smoking and drinking, living 99 years old is just a joke, and no one will really believe it. If you smoke, you should find that your nostrils are all yellow, black and gray, and your teeth may get darker and darker. You can imagine what your lungs look like. I clean my nostrils with facial tissue before going to bed every day, brush my teeth for 3 minutes, and never smoke after brushing my teeth. Smoking is harmful to health because tobacco contains a lot of nicotine, tar, nicotine and other harmful substances, which are not only harmful to yourself, but also harmful to people around you. For many people, smoking is a way to relieve themselves, relieve stress and refresh themselves; I feel tired and sleepy when I finish one thing and think about a question. I always want to light a cigarette. However, according to the latest research abroad, smoking can't reduce people's anxiety. On the contrary, if you can quit smoking successfully or for a long time, people's anxiety will be significantly reduced. The difference between e-cigarettes and real cigarettes is precisely because we know that smoking is harmful to health and many people have the need to quit smoking, so some companies have developed the product of e-cigarettes. E-cigarette is different from ordinary cigarettes. It does not contain tar hydrocyanic acid, acrolein, arsenic, lead, mercury and other harmful substances, nor does it cause harm to others, environmental pollution and fire hazards caused by second-hand smoke. Therefore, it can be used in places where smoking and fire are prohibited. E-cigarettes are the same as ordinary cigarettes. They don't change people's smoking habits, but they still smoke, giving people the same or even better smoking feeling. Another difference is the price of electronic cigarettes. E-cigarettes are generally more expensive than ordinary cigarettes, but they can be reused. Long-term use can save a lot of money on cigarettes. Moreover, the effective use of e-cigarettes can reduce the dependence on cigarettes and achieve the effect of slowly quitting smoking. Is electronic cigarette useful for quitting smoking? In 2008, the World Health Organization issued a statement saying that there was no evidence to support the claim that e-cigarettes helped to quit smoking. However, from the feedback of e-cigarette users around the world, e-cigarettes do have the ability to replace ordinary cigarettes, reduce the harm to themselves and their families, and alleviate the dependence on cigarettes to some extent. For a person who has smoked for many years, long-term smoking has made the body dependent on nicotine, and a large amount of smoke poison produced by nicotine has also been deposited in the lungs and blood of people, and the human body has lost its antibody to nicotine. In order to truly achieve the goal of quitting smoking, it is necessary to remove the smoke poison from the lungs, restore the body's own antibody ability, and make smokers have a smoke reaction. With the discharge of lung toxins, antibodies naturally accumulate and increase in the body, and smokers' addiction can gradually decrease, thus smoking. Until it is eliminated, so as to quit smoking quickly, safely and effectively. According to the introduction of some e-cigarette products, e-cigarettes contain plant detoxification components, which can effectively remove harmful substances accumulated in the lungs and reduce dependence on nicotine. The process of e-cigarette smoking cessation is to change cigarettes-control cigarettes-clear cigarette poison. Whether you can quit smoking successfully is also related to people's willpower. Is e-cigarette harmful? E-cigarette controls the output and working state of smoke through high-tech silicon chip and airflow sensor. Nicotine is atomized, and the solution containing nicotine and essence is atomized into particles, which are absorbed by the lungs and spit out simulated smoke. Does not contain harmful components such as tar in cigarettes, does not produce second-hand smoke, and does not spread or curl up in a closed space; Traditional cigarettes are lit by tobacco leaves or tobacco, which is harmful to the health of smokers and non-smokers. So if you want to ask what harm e-cigarettes have? The answer is no. Electronic cigarettes are harmless.

Question 5: Is e-cigarette harmful to human body? Disease analysis: Hello, it depends on the principle of electronic cigarettes. Electronic cigarette controls smoke output and working state through high-tech silicon chip and airflow sensor, nicotine is atomized, and the solution containing nicotine and essence is atomized into particles, which are absorbed by the lungs and spit out simulated smoke. Suggestion: Therefore, e-cigarettes do not contain tar and other harmful components in cigarettes, and will not produce second-hand smoke, nor will they spread or stay in confined spaces, so they will not cause harm to human bodies, and many people around them will respond well. I hope it helps you and I wish you good health.

Question 6: The harm of electronic cigarettes 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, it plays the role of a fashion plaything. It has various appearances and hundreds of flavors. It can also smoke, and it smells and feels like a cigarette. E-cigarette is a cigarette imitation device composed of lithium battery, atomizer and cigarette bomb. The liquid containing nicotine is evaporated by atomizer and inhaled directly, but no smoke will be produced in the process. E-cigarettes have no harmful components such as tar and suspended particles 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 to replace cigarettes in current fashion. Some studies have pointed out that 85% of smokers are not really addicted, but actually just an addiction in behavior habits. View details >>

electronic cigarette

In recent years, with the non-stop anti-smoking movement all over the world, e-cigarettes came into being and became very popular. It is estimated that there are about 654.38+0 million smokers in the United States and Europe who regularly consume electronic tobacco products. This portable electronic atomizer, which imitates cigarettes, was invented and patented by China people. E-cigarettes make propylene glycol or glycerol into a mist, so that it can be inhaled directly into the human body, which looks like smoking.

However, in recent years, scientific research institutions have continuously proved through experiments that e-cigarettes are harmful to the human body, even more harmful than traditional cigarettes, calling on * * * to take control measures.

Structure and basic principles

Structure of electronic cigarette

The appearance of e-cigarette is similar to that of traditional cigarette, but its internal structure is quite different. It is generally composed of battery stick, atomizer and smoke bomb. The atomizer is powered by the battery, which can turn the liquid nicotine in the cigarette bomb into mist, so that the user has a feeling similar to smoking when smoking.

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 naturally addicted. Sellers package e-cigarettes into pollution-free smoking cessation products, the principle of which is to gradually reduce the nicotine content in smoke bombs and help smokers get rid of nicotine dependence and quit smoking. Harm of electronic cigarette

Causing lung contraction and inflammation.

E-cigarettes are no less harmful than traditional cigarettes.

20 12 was funded by the Greek cancer society, and Constantine, chief researcher of the Center for Global Tobacco Control of Harvard School of Public Health? Vadavas and his colleagues tested 30 healthy smokers in Athens, Greece, and observed the changes of their respiratory tract after using electronic cigarettes.

The researchers found that five minutes after smoking e-cigarettes, their lungs showed signs of contraction, and combined with other breath tests, they also found symptoms of inflammation. This is the first time that there is evidence that just using e-cigarettes can have such a strong * * * effect on the respiratory system.

It is not clear whether this short-term lung reaction will have long-term health effects, such as emphysema and other lung diseases. However, the researchers stressed that if it only takes a few minutes to cause changes in the respiratory system, then the possible consequences of long-term repeated use of e-cigarettes have to be taken seriously.

High nicotine content is easy to cause cancer.

Elizabeth, director of the German Federal Center for Health Education? Dr. Porter said that e-cigarette manufacturers added a large amount of propylene glycol as a humidifier in order to evaporate liquid nicotine in cigarette bombs and make them smoke. Propylene glycol can account for up to 90% of the liquid content in smoke bombs. This substance is easy to * * * respiratory tract, and then causes some acute symptoms, which may be more harmful to health than traditional cigarettes.

In addition, a French study shows that the use of e-cigarettes can also lead to cancer. According to the data of French National Institute of Consumption, some e-cigarettes have high nicotine content, and some e-cigarettes contain carcinogens that are no less harmful to human health than ordinary cigarettes. Therefore, e-cigarettes can also cause harm to the body and cause cancer just like ordinary cigarettes.

At the same time, because the electronic cigarette device heats up too fast, a highly toxic molecule called acrolein will be produced in this process. Inhalation of acrolein may damage the respiratory tract, leading to pharyngitis, chest compression and bronchitis; Inhalation can cause pneumonia, pulmonary edema, shock, nephritis and heart failure.

For children, liquid nicotine in e-cigarettes can be fatal. However, the researchers pointed out that there is no reason to ban the use of ... >; & gt

Question 7: Which is more harmful, e-cigarettes or ordinary cigarettes? Ordinary cigarettes, with too many toxins, will lead to addiction and it is not easy to quit. E-cigarettes can choose different materials of cigarette oil, which will not be greatly affected. It's just that fun e-cigarettes are less harmful and addictive cigarettes are more harmful.

Question 8: Is e-cigarette harmful? What are the hazards of e-cigarettes? It must be affirmed that e-cigarettes can not only help to quit smoking, but also do harm to the health of the formula.

In recent years, various electronic cigarettes have appeared on the market. Because e-cigarettes don't burn or use tobacco leaves, but vaporize liquid, manufacturers claim that inhaling e-cigarettes is harmless to health. However, on August 26th, 20 14, the Report on the Health Effects of E-cigarettes issued by the World Health Organization in Geneva pointed out that e-cigarettes are harmful to public health. Besides nicotine, there are other toxic, harmful and carcinogenic substances in the smoke of e-cigarettes. In some brands of electronic cigarettes, the contents of some carcinogens (such as formaldehyde) and toxic substances (such as acrolein) are as high as those in ordinary cigarette smoke.

In fact, there is no sufficient scientific basis for whether e-cigarettes can promote long-term smoking cessation, and the safety of e-cigarettes has attracted more and more attention. It has been reported recently that smoking e-cigarettes is not conducive to smokers' success in quitting smoking. Moreover, smokers in smoking cessation clinics generally report that it is impossible to quit smoking with e-cigarettes. So don't quit smoking by e-cigarettes, and also oppose people who don't smoke traditional cigarettes, especially teenagers.

So are there any other ways to quit smoking? I will introduce some common methods of quitting smoking at present, so that everyone can have a comprehensive understanding of the methods of quitting smoking and help everyone quit smoking successfully.

The first is the most common method of quitting smoking by willpower alone, which is what we often call "quitting smoking". This method is most familiar to everyone. The advantages of this method are low threshold, safety and no side effects. The disadvantage is that the success rate is too low. No more than 3% people quit smoking by perseverance and can keep smoking 1 year. Smoking is not only a bad habit, but also a failure of perseverance. In fact, it is a chronic disease-tobacco dependence syndrome, mainly caused by nicotine, an addictive substance in tobacco. This is why it is so difficult to give up smoking. Mutual support and encouragement of quitters when quitting smoking can increase confidence and motivation. At present, the main smoking cessation communities in China are: Smoking Cessation Corps APP, WeChat official account to accompany me to quit smoking, and WeChat official account to quit smoking.

The second kind is commonly used drugs in smoking cessation clinics, and the development of smoking cessation drugs has a history of N years. Advantage is the only effective smoking cessation method recognized by the medical community at present. A large number of clinical research data and clinical applications from dozens of countries around the world have proved its effectiveness and safety. At present, the first-line smoking cessation drugs recommended by smoking cessation guidelines are: Niklan tartrate (trade name Chang Pei), nicotine replacement therapy drugs (the dosage form available in China is patch (also called smoking cessation patch)) and bupropion hydrochloride sustained-release tablets (trade name Yue Ting).

Clinical trials show that the success rate of drug smoking cessation is generally higher than that of dry smoking cessation. Among them, the success rate of Niklan tartrate in quitting smoking is about 50%. The success rate of nicotine patch and bupropion hydrochloride sustained-release tablets is about 30%. But at present, the public has little contact with smoking cessation drugs, and many people are worried about the side effects of drugs. In fact, smoking cessation drugs have relatively few side effects and can be used safely. The most common adverse reactions of Niklan tartrate (Changpei) are nausea and dreaminess. The most common adverse reaction of nicotine patch is skin allergy; The most common adverse reactions of bupropion hydrochloride sustained-release tablets (Yueting) are dry mouth, nausea and insomnia.

At present, drugs can be bought in smoking cessation clinics and online pharmacies in major hospitals.

So how is the best way to quit smoking? First of all, you can evaluate the degree of nicotine dependence: can you use Fagerstr? M tobacco dependence scale evaluates the degree of tobacco dependence of smokers (see the table below).

0~3 points, mild tobacco dependence; 4~6 points, moderate tobacco dependence; ≥7 points, severe tobacco dependence.

Smokers who are not addicted or lightly dependent on tobacco can quit smoking by their own perseverance, but it is best to have the support and encouragement of relatives and friends. In addition, smokers need to create a smoke-free environment before quitting smoking, make a smoking cessation plan that suits them, carry out self-goal management and stick to it.

For smokers with moderate or severe tobacco dependence, it is suggested that it is best to quit smoking scientifically with the help of doctors. For those who have failed to quit smoking many times, it is suggested not to be depressed, but to seek professional guidance from doctors and take effective measures to quit smoking successfully. In fact, according to the standards of the World Health Organization, tobacco addiction, like heroin addiction, is a chronic addiction disease. Therefore, experts point out that quitting smoking scientifically requires personal will, support and help from family and friends, and guidance from professional doctors and medication. Drug, psychological, behavioral and other comprehensive treatment means can easily quit smoking, and only in this way ... >>

Question 9: How harmful is e-cigarette? Which is more harmful, e-cigarette or real cigarette? 20 12 was funded by the Greek cancer society, and Constantine, chief researcher of the Center for Global Tobacco Control of Harvard School of Public Health?

However, the researchers stressed that if it only takes a few minutes to cause changes in the respiratory system, then the possible consequences of long-term repeated use of e-cigarettes have to be taken seriously.

High nicotine content is easy to cause cancer.

Elizabeth, director of the German Federal Center for Health Education? Dr. Porter said that e-cigarette manufacturers added a large amount of propylene glycol as a humidifier in order to evaporate liquid nicotine in cigarette bombs and make them smoke. Propylene glycol can account for up to 90% of the liquid content in smoke bombs.

Inhalation of acrolein may damage the respiratory tract, leading to pharyngitis, chest compression and bronchitis; Inhalation can cause pneumonia, pulmonary edema, shock, nephritis and heart failure.

For children, liquid nicotine in e-cigarettes can be fatal. However, the researchers pointed out that there is no reason to ban the use of e-cigarettes for the time being, and there are no special measures to protect children from the harm of e-cigarettes.

In 2009, 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.

Who does not recognize its smoking cessation effect.

In September 2008, the World Health Organization issued a public statement on "e-cigarettes", saying that there is no scientific evidence to prove that e-cigarettes are safe and effective smoking cessation tools. WHO has never considered e-cigarettes as a legal nicotine substitute to help smokers quit smoking.

Attitudes of countries towards e-cigarettes

Comprehensive prohibition

At present, e-cigarettes have been banned in Canada, Norway, Switzerland, Turkey, the United States, Australia, Brazil, Argentina and other countries.

Their health department believes that e-cigarettes are not as healthy and harmless as advertised by manufacturers, and contain a certain amount of carcinogens and nicotine, so sales and consumption should be banned. The Centers for Disease Control and Prevention of American medical and health institutions reminded that among young people, including those who have never smoked, e-cigarettes should be accurately positioned and prohibited from being sold to minors.

Relative prohibition

When the European Commission revised the EU Tobacco Products Directive, it 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 limited.

In Hanover, Germany, it is forbidden to "smoke" e-cigarettes in public offices and cars, while in Italy and France, it is forbidden to sell e-cigarettes to minors.

Question 10: Is electronic cigarette more harmful than real cigarette? E-cigarettes are more harmful than real cigarettes?

The harm of e-cigarettes is certainly much less than that of real cigarettes, and the oil of e-cigarettes is also nicotine-free, which can help smokers quit smoking effectively and gradually and avoid the poison of more than 7,000 other harmful substances in cigarettes.

According to statistics, there are about 130 e-cigarette manufacturers in China, most of which have their own brands. In terms of scale, Haoyikang e-cigarettes are the most competitive. Haoyikang is currently the world's leading e-cigarette brand, which is famous for its military quality.
