What are the benefits and disadvantages of e cigarettes?

1.In just 1 month, users who switched to e-cigarettes experienced significant improvements in endothelial function and vascular stiffness compared to those who continued to use combustible cigarettes.

2.Switching to e-cigarettes can reduce the burden of cardiovascular disease, but because the use of e-cigarettes may cause sudden problems such as increased blood pressure and heart rate, the use of e-cigarettes is not completely harmless to the human body.

3.While not completely risk-free, e-cigarettes are less harmful to respiratory health than traditional cigarettes.

4.There is growing evidence that e-cigarette emissions are safer for the respiratory tract than smoke from combustible tobacco.

5.Switching to e-cigarettes altogether may significantly reduce smokers' exposure to cadmium or lead. Exposure to carcinogenic cadmium decreased dramatically after cigarette change.

The study concluded that e-cigarettes may have potential toxicological and biological effects on health, although they still contain various compounds. However, when smokers switch to e-cigarettes completely and are no longer affected by the smoke of combustible tobacco, beneficial changes occur in their bodies.

Summary. 1) Healthier.

Soot-free does not require combustion, and e-cigarettes are quite eco-friendly and do not produce soot or cigarette butts.

2) No smoke odor.

E-cigarettes don't emit a disgusting snuff smell that won't leave your clothes, hair, household items, etc. on the smell. E-cigarette smoke has a sweet flavor and can quickly evaporate into the air.

3) E-cigarettes are healthier than cigarettes; No tobacco, no tar or related toxins. When using e-cigarettes, it will not inhale more than 4000+ chemicals and more than 40 carcinogens due to burning tobacco.

4) No secondhand smoke.

The smoke of e-cigarettes contains water and easily disappears in the air.

5) No tar staining teeth.

E-cigarettes don't tar your teeth turn yellow.

6) No bad breath.

E-cigarettes do not have bad breath.

7) More environmentally friendly.

Unlike ordinary cigarettes, e-cigarettes do not have cigarette butts and are an environmentally friendly product that can be reused.

Seven benefits of e-cigarettes.

Dear, do you have any other questions, dear, I hope mine can help you.

E-cigarettes mainly have the following aspects:1. E-cigarettes are easy to cause cancer.

E-cigarettes also contain carcinogens, and their carcinogenicity may not be lower than that of traditional cigarettes. E-cigarettes contain benzene, a substance that can be detected in the smoke produced after the pod is fully vaporized, with a content nearly 1,000 times higher than that of ordinary air. This substance can easily cause malignant diseases such as leukemia and bone marrow failure.

2. Affect lung health.

Long-term use of e-cigarettes can easily lead to lung health damage, because e-cigarettes also contain substances that are not good for human lung health, and even no less toxic substances than real cigarettes. Under the influence of prolonged smoking, the function of the lungs is impaired, and the mucosal tissues of the lungs are damaged, which also causes diseases. Therefore, if you want to maintain lung health, you should stay away from e-cigarettes.

3. Cause damage to the cardiovascular system.

Nicotine is contained in the cigarette, which can cause cardiovascular discomfort and harm to the cardiovascular system after excessive invading. Symptoms of nicotine poisoning include dizziness, nausea, high heart rate, and increased blood pressure, which in turn leads to atherosclerosis, and an increased probability of myocardial infarction.

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 harmful to the body, and to some extent, they are even more harmful than traditional cigarettes.

E-cigarettes, the World Health Organization calls it an "electronic nicotine delivery system", of course, there are a small number of e-cigarettes that do not contain nicotine. Taking e-cigarettes containing nicotine as an example, the harm to the body is mainly in the following aspects:

First of all, the main ingredient in e-cigarettes is nicotine, which is the same as the main ingredient of traditional cigarettes, and its harm is self-evident. And young people who use e-cigarettes containing nicotine may become addicted and are likely to end up as cigarette smokers.

Secondly, e-cigarettes release aerosols, which contain ethylene glycols, aldehydes, polycyclic aromatic hydrocarbons, metals, silicate particles, etc., some of which are carcinogens.

In addition, some e-cigarettes add a variety of additives and flavorings to the cigarette liquid, such as chocolate flavor, coffee flavor, as well as lemon, strawberry, mango and other fruit flavors, these additives or flavorings will produce harmful substances after heating, and there are unknown health risks.

Special reminder: China has not yet issued quality management standards for e-cigarettes and related products, and the quality of e-cigarette oil sold on the market is uneven, so the harm of e-cigarettes is no less than that of traditional cigarettes.

Most e-cigarettes contain the addictive substance nicotine, due to the mixed e-cigarette market, the quality of e-cigarette products is uneven, and the nicotine content in some e-cigarettes far exceeds the actual labeled content, which is not only easy to make people addicted, but also has a huge health risk to the human body.

Second, after e-cigarettes are heated, aerosols will be released, producing carcinogens such as benzene, formaldehyde, and nitrosamines. As the temperature increases, more and more carcinogens are produced, greatly increasing the risk of cancer such as lung cancer.

Article **4 Third, there are a variety of heavy metals in e-cigarettes, especially nickel and chromium, which are biologically toxic, and are difficult to be degraded after entering the body, and will continue to accumulate, which may cause chronic poisoning.

Fourth, there are some unknown risks, at present, e-cigarettes are difficult to produce in accordance with international mandatory standards, and it is easy to mix into inferior e-cigarette products with unknown formulas, and there are not enough disease samples for further analysis, and some potential risks to health are still unknown.

1.E-cigarettes can increase the success rate of bacteria invading the human body. Relevant studies have shown that due to the structure of e-cigarettes and their special working principle, through the bacteria and toxic substances after the cigarette stick is vaporized, their viscosity will be enhanced, and at the same time, these harmful substances also form a protective film on the surface with the help of e-cigarettes, which makes it easier for harmful substances to attach to human epithelial cell tissues and become easier to survive under the body's defense mechanism.

2.Damage to the respiratory tract, nasal cavity and oral mucosa. The liquid of e-cigarettes contains formaldehyde.

If formaldehyde enters the respiratory tract through the mouth and nose, it can cause symptoms such as nasal and throat allergies and severe cough. The risk of leukemia is also greatly increased by long-term e-cigarette use.

3.Damage to the cardiovascular system. If you inhale too much nicotine in the cigarette liquid, the cardiovascular system will feel uncomfortable, which can cause serious harm to the cardiovascular system.

Nicotine poisoning can cause symptoms of nausea, dizziness, increased blood pressure, high heart rate, atherosclerosis, and increased probability of myocardial infarction.

E-cigarettes are also harmful to the body, because e-cigarettes are heated by electronic liquid nicotine, so that the liquid nicotine volatilizes into the body to produce the smoking effect, nicotine is still harmful to the body after heating, can quickly constrict blood vessels to increase blood pressure, and cause significant pressure on the heart, especially the endothelial cells and surfaces of the cardiovascular system, so the greatest danger 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 increase the incidence and incidence of stroke, cerebrovascular accident, and so on. Although e-cigarettes have a relatively lower infection rate to the lungs and a lower incidence of lung cancer than conventional cigarettes, e-cigarettes still pose an irreplaceable danger to cardiovascular and cerebrovascular endothelial cells.

1. Smoking too many e-cigarettes is extremely harmful to health. E-cigarettes are a product that mimics tobacco cigarettes, claiming to be free of tar and carbon monoxide, which makes many people mistakenly think that they are healthier than real cigarettes, but in fact, e-cigarettes are no less harmful than real cigarettes.

2. E-cigarettes, like paper cigarettes, contain nicotine, which is a highly addictive substance and is dangerous. Nicotine in doses below 50 mg can lead to respiratory failure and paralysis. In small cases, it can cause toxic symptoms such as nausea, dizziness, decreased blood pressure, and heart palpitations.

Nicotine, even when ingested in small amounts, constricts blood vessels, increases heart rate, and affects the central nervous system. Nicotine increases the likelihood of heart disease in smokers. In addition, it may promote tumor growth caused by carcinogens.

3. Most flavored e-cigarette oil contains chemicals that are harmful to the human body, and these chemicals will cause certain damage to the lungs, resulting in difficulty breathing.

4. In order to make better profits and taste, some businesses violate relevant regulations when manufacturing e-cigarette oil, and add 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.

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.

Shenzhen and Hangzhou have controlled e-cigarettes.

Many users of e-cigarettes do not think of themselves as smokers, but prefer to be called gamers. They think the feeling of "swallowing clouds and spitting smoke" is very cool, which has driven a large number of young people to start trying e-cigarettes. Jiangsu disease control experts said that after Shenzhen, Hangzhou has also issued a policy to officially include e-cigarettes in the scope of tobacco control.

It's not reliable to expect to quit smoking through e-cigarettes. Reasonable smoking cessation begins with an assessment of tobacco dependence, which is mainly based on measuring the degree of nicotine dependence and thus estimating the degree of tobacco addiction. If you have a mild to moderate addiction, you can use a gradual reduction method, and you can also replace nicotine **, try nicotine gum, etc.

However, for moderate to severe smokers, the use of smoking cessation drugs should also be encouraged. Patients with different levels of addiction to cigarettes take different medications. For severe smokers, psychological** may be required.
