How about the harm of e cigarettes Are e cigarettes harmful?

E-cigarettes are harmful to the body, e-cigarettes are electronic products that imitate cigarettes, it has the same appearance as cigarettes, smoke taste and feeling, and is a product that allows users to smoke nicotine and other materials after turning them into vapor by means such as atomization. The World Health Organization has conducted a special study on e-cigarettes and concluded that e-cigarettes are harmful to public health and are not a means to quit smoking, and management must be strengthened to eliminate harm to adolescents and non-smokers. Studies have shown that when people use e-cigarettes, in addition to nicotine, they may also inhale other undiscovered toxic compounds into the body, and e-cigarettes can also harm the health of people around them like second-hand smoke, which will release inhalable liquid fine particles and ultrafine particulate matter, nicotine and carcinogens into the room.

Since e-cigarettes do not produce smoke, it is easy to mislead consumers into believing that it is safe and healthy, which is a wrong perception.

Because most e-cigarettes have nicotine like regular tobacco, nicotine is addictive and harmful to fetal development, causing damage to the brain development of people aged 20 and younger.

E-cigarettes also contain harmful aerosols. This aerosol contains chemicals and heavy metals that are harmful to the human body.

E-cigarette batteries rarely malfunction, but if they do, there is a risk of burning hands, face, etc. According to the U.S. Centers for Disease Control and Prevention, children and adults have been poisoned by swallowing, inhaling, or eye contact with cigarettes.

Some e-cigarette merchants will launch a variety of different flavors of e-cigarettes, such as fruit flavors, to attract young smokers. However, Dr. Robert Jackler, chair of the Department of Otolaryngology and professor of otolaryngology at Stanford University, points out that condiments are safe to eat and are not a problem for the digestive system, but there may be risks associated with allowing condiments to enter the lungs. We know that inhaling these condiments in some factories that produce them is inherently dangerous.

1 Dangerous substances in e-cigarettes.

Nicotine. In order to make e-cigarettes have the taste of cigarettes, merchants will add a small amount of nicotine to the e-cigarette oil, and long-term absorption of nicotine is very harmful to the body, and excessive use will lead to dizziness, vomiting, and in severe cases, poisoning. And long-term exposure to nicotine can create dependence.

Lithium battery. E-cigarette is a kind of electronic product, e-cigarette in the process of use is indispensable battery, some e-cigarette battery quality is poor, without safety and quality inspection, there is a great danger when smoking e-cigarettes, and even may cause **.

Various scents. Most flavored e-cigarette liquids contain chemicals that are harmful to the human body, and these chemicals will cause some damage to the lungs, resulting in difficulty breathing.

Hazardous substances. In order to make better profits and taste, some businesses violate relevant regulations when manufacturing e-cigarette liquid, adding some harmful or even toxic substances to it. For example, nitrosamines, plasticizers and heavy metals, etc., these substances can cause great harm to the human body.

2 Tips.

After reading the above article, we should have a general understanding of the harm of e-cigarettes, for our health, it is best to refuse cigarettes, and friends who quit smoking also choose a scientific way to quit smoking, even if they buy e-cigarettes to quit smoking, they should also buy them in regular shopping malls.

E-cigarettes are also harmful to the body, because e-cigarettes are used to heat liquid nicotine by electronics, so that the liquid nicotine volatilizes into the body to produce a smoking effect, nicotine is still harmful to the body after heating, can quickly constrict blood vessels and increase blood pressure, and cause significant pressure on the heart, especially the cardiovascular endothelial cells and surfaces, so the most harmful when smoking e-cigarettes is the cardiovascular system. Long-term smoking of e-cigarettes will significantly aggravate the incidence of cardiovascular diseases, such as acute coronary syndrome, acute myocardial infarction, acute pericarditis, acute myocarditis and other diseases, and will also aggravate the incidence and incidence of stroke, cerebrovascular accident, etc. Although e-cigarettes have a relatively lower infection rate of the lungs and the incidence of lung cancer than conventional cigarettes, e-cigarettes still have irreplaceable harm to cardiovascular and cerebrovascular endothelial cells.

Under the anti-smoking boom, many people have begun to promote e-cigarettes, but the harm of e-cigarettes may be even greater!

Are e-cigarettes harmful to the body?

E-cigarettes are actually the same as ordinary cigarettes, but ordinary cigarettes, it has flammability, for example, it is easy to cause disasters without paying attention to it, causing a fire somewhere, and e-cigarettes, it is a kind of smoke transmission by heating liquid nicotine to satisfy their own smoking feelings.

Compared with ordinary paper cigarettes, the biggest advantage of e-cigarettes is that they will not cause disasters, and they are not so disgusted by the people around them, and e-cigarettes have a variety of flavors, so girls often prefer e-cigarettes.

E-cigarettes are heated with liquid nicotine, which is harmful to the body, constricting blood vessels and increasing blood pressure, but also putting pressure on the heart. So e-cigarettes are harmful to health because they can cause heart attacks and strokes.

E-cigarettes are only less harmful than ordinary tobacco, and the second-hand smoke produced by e-cigarettes will also harm human health. Long-term inhalation of e-cigarettes, such as e-cigarette addiction, cardiovascular diseases, lung diseases, etc., the specific hazards are as follows:

1. E-cigarette addiction: Because e-cigarettes also contain a large amount of nicotine, and the nicotine content in e-cigarettes is higher than that in ordinary cigarettes. When smoking, this nicotine component is inhaled from the nose and then enters the brain, where it prompts the brain to produce dopamine components, which give pleasure to the smoker, leading to the symptoms of e-cigarette addiction.

2. Cardiovascular disease: e-cigarettes heat liquid nicotine through electronics, so that liquid nicotine volatilizes into the body to produce a smoking effect, nicotine heating still has a certain harm to the body, nicotine spreads to the whole body through the lung mucosa and oral mucosa, and after entering the brain, nicotine can imitate acetylcholine, a central neurotransmitter, and bind to nicotine receptors on the surface of many neurons. By activating the nerves involved, it can release more dopamine.

Because the role of dopamine, serotonin and norepinephrine is strengthened, blood vessels can rapidly constrict blood vessels, increase blood pressure, and produce significant pressure on the heart, especially the endothelial cells and surfaces of the cardiovascular system, so vaping is the most harmful.

3. Lung diseases: The main components of e-cigarettes are nicotine, vegetable glycerin, propylene glycol, etc., and most e-cigarettes have high nicotine content. When the body ingests nicotine, it gradually destroys certain structures in the lungs.

Bronchial epithelial cells and bronchial epithelial cells are destroyed, causing lung mucus cells to secrete a large amount of mucus, forming chronic bronchitis, chronic pharyngitis and other diseases. Smoke contains many chemicals, such as glycidyl, vitamin E, acetate, ultra-fine particles, nicotine and carcinogenic substances, if inhaled into the lungs for a long time, it will cause damage to the lungs, and the role of lung cells is mainly to repair DNA damage and prevent cancer, so low levels of lung cells will lead to DNA damage, thereby increasing the incidence of lung cancer.

E-cigarettes are a very popular and fashionable daily necessities. At present, the main ingredients of e-cigarettes are propylene glycol and nicotine, which can partially replace smoke after inhalation.

Propylene glycol and nicotine, although they are a little less harmful than ordinary cigarettes, do not mean that they are not harmful. Some people will have a severe allergic reaction after inhalation, nicotine can excite the nerves, but if you smoke for a long time, the human body will become dependent on nicotine and become addicted to smoke, resulting in the inability to quit smoking.

E-cigarettes are harmful to the human body, and the reason why this product is loved by smokers is because of its ability to produce nicotine, but not through tobacco burning, but through the release of e-liquid inside. Nicotine is a substance that is harmful to the human body. E-cigarettes produce large amounts of smoke, which are inhaled into the lungs of the human body and can damage the lungs of patients.

Moreover, under the action of high temperature, the substances contained in e-cigarettes may decompose into other harmful substances. Although it is less harmful than direct smoking, it is not recommended. E-cigarettes are more harmful than regular cigarettes and may affect the function of the immune system, leading to a decrease in immunity, especially e-cigarettes with aromatic additives.

In addition, e-cigarette users are more likely to experience irregular heartbeats, heart attacks, and sudden death. The 2019 Global Tobacco Epidemic Report released by the WHO not long ago pointed out that e-cigarettes are neither safe nor healthy, and can cause a series of pathologies or poisoning in the human body due to the toxic substances and pollutants contained in the smoke of the electronic nicotine delivery system. Moreover, there is no good reason why e-cigarettes help smokers quit.

The biggest harm of e-cigarettes is to induce teenagers to smoke the "first cigarette" and cultivate more future smokers. 71% of teenagers believe that e-cigarettes are safer than traditional cigarettes, coupled with the lack of restrictions on e-cigarette advertising sales channels, which increases the purchase rate of minors.

E-cigarettes are harmful. The nicotine in e-cigarettes can have a negative impact on teenage brain development, which can cause consequences such as nicotine addiction, mental disorders, poor concentration, and decreased learning ability. "Although many people smoke e-cigarettes to quit smoking, the use of e-cigarettes may still contribute to their addiction to other tobacco products, alcohol, drugs, etc.

Not only is it harmful to the smoker's body, but the secondhand smoke of e-cigarettes is still harmful. "There are health risks associated with prolonged exposure to nicotine in minors, pregnant women and non-smokers, inhalation of other toxic emissions from these products, and inhalation of second-hand emissions. Wu Di said that nicotine is a highly toxic chemical, and the respiratory system of minors is not yet fully developed, and inhaling e-cigarettes may also lead to nicotine poisoning and other safety risks.

At present, the nicotine content of some e-cigarette e-liquids on the market is not standardized, and such safety risks cannot be ignored. ”

And the harm of hookah is even more surprising. Wu Di told reporters that the World Tobacco Atlas launched at the 16th World Conference on Tobacco and Health shows that the amount of cigarettes inhaled from a hookah pipe is almost equal to the amount of a whole cigarette inhaled. "Hookah contains carcinogens and toxic substances, such as nitric oxide and heavy metals.

Therefore, the use of hookah is as harmful to human health as the use of cigarettes and tobacco. Wu Di said.
