Are E-Cigarettes Harmless and Allowed in Public Places?

As a substitute for cigarettes, e-cigarettes have become famous all over the world since they emerged as a tool for quitting smoking, and have been out of control since then. In addition to the slogan of reducing focus and harm promoted by e-cigarettes themselves, with the advancement of technology, e-cigarette manufacturers have continued to improve their products, which has made e-cigarettes popular among young people. Unconsciously, smoking e-cigarettes has become a new fashion.

So, are e-cigarettes really natural and pollution-free? Why are the prices of commercial e-cigarettes uneven? Is it necessary to ban e-cigarettes in public places?

　　Sales surged 138%

As a consumer pastime, tobacco did not widely enter human society for a long time. It was not until the opening of the new sea route in the 16th century that it spread from America to Europe. As for China, the history of large-scale smoking of foreign cigarettes by the masses is actually less than 100 years old. In Lao She's drama "Tea House", the Hadmen cigarettes smoked by Tang Tiezui in the early years of the Republic of China were still called a rare product at that time. However, the development speed of cigarettes in China is very alarming. Statistics show that the number of smokers in my country reaches 350 million, ranking first in the world.

As we all know, long-term smoking has a greater impact on the cardiovascular, cerebrovascular and respiratory tract, and the special substances contained in cigarettes make people easily addicted. Against this background, a new type of electronic cigarette came into being, and its inventor turned out to be China Han Li.

Han Li's father died of lung cancer due to smoking, so he invented a nicotine e-cigarette product in 2003 and obtained an international patent in 2007, which was the famous Ruyan at that time. Many people still remember its advertising words. According to Han Li, he hopes that the product can help smokers eliminate the effects of smoking addiction.

Different from cigarettes, the name of e-cigarettes in English is Vape, and those who smoke e-cigarettes are also called the Vape family. The picture shows famous movie star Leonardo smoking e-cigarettes

To distinguish it from smoking cigarettes, e-cigarette enthusiasts coined the word Vape. It extends from the word vapour and refers to the act of smoking an e-cigarette. In 2014, Vape became the Oxford Dictionary's word of the year. The principle of an e-cigarette is not complicated. It consists of an e-cigarette smoking set and tobacco oil. Among them, the smoking set is an atomizing tool. When smoking is needed, the e-cigarette has a pneumatic switch. When it is inhaled, it is turned on, and the resistance wire heats up. It vaporizes the aromatic oil containing nicotine, and smokers inhale the vaporized aromatic oil and nicotine.

Ten years ago, in a TV advertisement, a middle-aged man told you that he no longer wanted to smoke after using e-cigarettes. Several foreign experts appeared saying this was the latest cutting-edge research result. But in comparison, current e-cigarette consumers are younger

Compared with ordinary cigarettes, there are no carcinogenic components such as tar, aldehydes, acids, and phenols among the components of e-cigarettes. Harmful gases will not be produced after burning, so many e-cigarettes have been marketed under the banner of health and environmental protection, and even said that their products have the function of detoxifying and clearing lungs. What followed was a significant increase in sales. Data showed that sales of heated non-combustible tobacco products in 2017 were approximately US$5 billion, an increase of 138% over 16 years, rapidly promoting the development of the e-cigarette industry.

E-cigarettes are also harmful to health, with excessive nicotine addiction leading to death

“E-cigarettes are not a substitute for cigarettes. Instead, they may cause a vicious cycle." Yang Gonghuan, former director of the Tobacco Control Office of the China Center for Disease Control and Prevention and a professor at Union Medical University, told the Beijing Science and Technology News| Science and client reporter, unlike what merchants promote, e-cigarettes are not“ natural pollution-free” products.

The reason why people become addicted to smoking is that nicotine is the substance that causes trouble. Nicotine is commonly known as nicotine. It is an unpleasant, bitter, colorless and transparent oily liquid substance. It plays an effect on the human peripheral nervous system and has no clinical application value. Nicotine is mainly found in tobacco leaves, and a small amount of nicotine is also found in the fruits of many Solanaceae plants such as tomatoes and wolfberry fruits. Scientific research believes that nicotine is currently one of the most difficult addictive substances for humans to quit.

The ingredients of tobacco oil are propylene glycol (PG), vegetable glycerin (VG) and nicotine, of which nicotine is the main cause of smoking addiction. Therefore, the main role of nicotine in e-cigarette liquid is to satisfy people's craving addiction, while PG is used for dissolution and VG is used to produce smoke.# p#pagination title #e#

Although scientific research shows that tar in cigarettes is the main carcinogen and carbon monoxide is the most harmful to the human body, this does not mean that nicotine is harmless to the human body. On the contrary, it also needs to be taken seriously. Yang Gonghuan said that in addition to nicotine being the main culprit of addiction, continuous repeated use of nicotine can also cause damage to endothelial cells in coronary arteries and peripheral arteries, increase heart working speed and increase blood pressure, which is an important factor in inducing coronary heart disease. Large doses of nicotine can cause vomiting and nausea, and in severe cases can even lead to death.

E-cigarettes contain nicotine. Nicotine increases the speed of the heart's work and causes increased blood pressure and reduces appetite. Large doses of nicotine can cause vomiting, nausea, and in severe cases, death

In addition to health damage, the use of e-cigarettes, especially for young people, not only prevents smoking, but also causes a vicious cycle of smoking. Yang Gonghuan explained that because e-cigarettes contain nicotine, they will not only be unable to quit smoking after long-term smoking, but will also make people more dependent on them; however, the taste of e-cigarettes is different from that of real cigarettes, and they are often expensive. As a result, many smokers will eventually switch back to smoking tar cigarettes, which not only fails to achieve the purpose of quitting smoking, but also plays a counter-promoting role. Reporters actually measured low-priced e-cigarettes, poor taste, less information, and unable to screw on the lid

It is understood that unlike traditional tobacco products, the classification of e-cigarettes is currently unclear whether they belong to tobacco products or electronic products. Therefore, domestic e-cigarette products currently lack a regulatory mechanism, and the quality of products on sale is also uneven. They are mainly sold online, with prices ranging from tens of yuan to several thousand yuan.

Yang Gonghuan said that as far as the current market is concerned, some low-cost e-cigarettes have simple packaging, rough workmanship, and poor craftsmanship. The selected tobacco oil is also low-cost products, which is harmful to human beings. E-cigarettes will produce a series of cracking reactions at high temperatures. Not only will there be formaldehyde, but also the atomized and heated metal wires will produce acute toxic heavy metals. Long-term ingestion is also harmful to the human body. In addition, the temperature of e-cigarettes often exceeds 400 degrees when heated, and inferior products are extremely prone to problems such as explosion.

To this end, the reporter browsed and searched some e-cigarette products on Taobao and found that most of these products sold for two to three hundred yuan, and were specially marked with labels such as smoke cessation tools and gifts. Many products can choose from the taste and taste, such as Yuxi taste, Chinese taste, etc., and even products with new flavors such as cherries and cola, and can choose from different cigarette oil concentrations.

The concentration of e-cigarette liquid refers to the level of nicotine in e-cigarette liquid. Many tobacco oil manufacturers can provide customization of the concentration of tobacco oil. For example, 6 mg of tobacco oil means that 1 ml of tobacco oil contains 6 mg of nicotine. In other words, the nicotine content in tobacco oil refers to the nicotine contained per milliliter. Taking 3 mg of tobacco oil commonly used in large smoke e-cigarettes, about 0.4 ml is the nicotine of a cigarette.

So, the reporter bought a low-priced e-cigarette priced at only 39 yuan for testing. This product was not marked with information such as power and tobacco oil composition when introduced. After receiving the goods, the tobacco oil packaging box and electronic cigarette packaging boxes are very simple, especially tobacco oil. Not only is the nicotine content not marked in a clear position on the packaging box, but the cigarette oil bottle cannot be completely fastened even after being unscrewed.

After following the steps to add tobacco oil, the reporter conducted a test. After smoking for a while, I only felt dry and tingling in my throat, and there was no taste of Zhonghua cigarettes at all. What is even more worrying is that the heater part of the tobacco rod has become severely heated. For safety reasons, the reporter had no choice but to stop the test.

At present, the e-cigarette market is mixed. The FDA and other departments in the United States supervise e-cigarettes, while e-cigarettes in China are unregulated. Although the World Health Organization recommends that governments should take measures to ban people from selling e-cigarettes to young people. The World Health Organization recommends banning people from smoking e-cigarettes in public buildings until studies show that the smoke from e-cigarettes is harmless to people around them. However, e-cigarette products have developed rapidly, so the safety and quality of their products must be regulated. In addition, consumers who are worried about their health can choose tobacco oil with low concentration or even zero nicotine content. After all, the higher the concentration of tobacco oil, the stronger the throat feeling it will bring.# p#pagination title #e#

　 Expert: It is reasonable to ban e-cigarettes in public places

In fact, among the topics related to e-cigarettes in the past six months, the biggest controversy has been smoking in public places. Not long ago, in the Beijing subway, a video of a female passenger who was discouraged from smoking e-cigarettes shouting abuse was very impressive. The Beijing City Tobacco Control Association also stated that popular e-cigarettes will also release harmful second-hand smoke, and smoking should be banned in public places, and plans to promote e-cigarettes to be included in the scope of tobacco control.

As we all know, second-hand smoke is extremely harmful to the human body, and some research results also believe that second-hand e-cigarettes released by e-cigarettes can cause lung diseases in the human body.

However, Yang Gonghuan told reporters that the nicotine in e-cigarettes is formed after atomization. The aerosol will be quickly diluted in the air, and the diluted aerosol will be difficult to be absorbed again. ldquo; There is currently no accurate evidence that the vapor and smoke released by e-cigarettes is harmful to the human body. rdquo; Because of this, the harmlessness of electronic second-hand cigarettes has become the best excuse for many people to smoke them in public places. Many people also openly believe that what they smoke is not tobacco products, so there is no reason to control them. In this regard, Yang Gonghuan believes that it is reasonable to ban the smoking of e-cigarettes in public places. Referring to the practices of some European and American countries, e-cigarettes have long been included in the control list.

The World Health Organization has long clearly pointed out that e-cigarettes are harmful to public health. Many countries and regions have already controlled e-cigarettes in public places and even explicitly banned the sale of e-cigarettes

“First of all, the smoke produced by smoking e-cigarettes is similar to, or even stronger than, ordinary cigarette smoke. This will bring visual misunderstanding and law enforcement difficulties. Some smoke alarms may even be triggered, causing unnecessary losses.& rdquo; Yang Gonghuan said. Secondly, e-cigarettes are not conducive to promoting tobacco control and smoking cessation. We should not encourage this kind of behavior. It is necessary to ban e-cigarettes in public places.

The reporter learned that countries around the world currently have different attitudes towards e-cigarettes, but most countries have strengthened control and supervision over this: in the United States, e-cigarettes are regulated by the Drug Administration; in New Zealand, e-cigarettes can be sold but cannot be advertised; in countries such as the United Kingdom and Singapore, e-cigarettes are listed as drugs for sale; while in countries such as Canada and Singapore, e-cigarettes are products that are banned from sale, and users can only trade them through the black market. China has also repeatedly called for the State Food and Drug Administration to supervise e-cigarette products.

Yang Gonghuan emphasized that smoking addiction is a mental and neurological disorder, and the World Health Organization has a detailed classification code for this. Smoking e-cigarettes for whatever purpose is not a behavior worth encouraging, and people who quit smoking must use scientific methods. For e-cigarettes themselves, their rapid development will inevitably have a continuous impact on the traditional tobacco market. Therefore, the industry also needs to continuously promote the development of the industry to improve the development space of the industry.
