Cigarettes belong to the first level of carcinogens has been the public consensus, but in recent years, there is another seemingly “technological content” higher “electronic cigarettes” came out and hot sales,.

due to the e-cigarettes vaping and traditional tobacco is not quite the same way, many people think that it is compared to traditional tobacco Many people think that vaping are healthier than traditional cigarettes, so they smoke them with confidence and boldness, but is this really the case? Today, let us unveil the vape cover up:

4. What are the possible hazards of e-cigarettes?

 

As the market for e-cigarettes expands and the ingredients change, the latest expert opinion from the field of public health and safety suggests that the hazards of e-cigarettes need to be taken seriously:

 

• There are thousands of popular e-cigarette flavors on the market that incorporate flavoring agents, and it is not clear whether these compounds are toxic to the respiratory system. In addition, the extensive use of protonated nicotine (nicotine salts) has resulted in nicotine levels in e-cigarette liquids currently available on the market that can be as high as 60 mg/mL, and therefore may promote increased nicotine inhalation and its dependence among consumers.

 

• The vaping liquid includes volatile aldehydes, including formaldehyde, acetaldehyde, and vinyl alcohol, which have toxic effects on the cardiovascular and respiratory systems .

 

• The popularity of e-cigarettes among adolescents and young adults, and the elevated concentrations of nicotine and marijuana in e-cigarettes may increase addiction and the probability of using traditional tobacco among these potential smokers.

 

• There is indeed a difference between the toxic substances contained in e-cigarettes and traditional tobacco, but their toxic side effects are also related to their respective methods of use and the amount of use, and it is not possible to say that e-cigarettes contain fewer types of toxic substances and that they are harmless.

 

• The market standardization of e-cigarettes is still imperfect. Different countries and different manufacturers of different product types have different technologies and different compositions, which also makes it difficult to assess the health hazards of e-cigarettes.

 

Regarding the long-term hazards of e-cigarettes, the occurrence of the following events is a wake-up call for us:

 

In the summer of 2019, a large number of adolescents (10-19 years old) in the United States sought medical attention for symptoms such as shortness of breath and dyspnea, which were later investigated and analyzed to show that acute lung injury occurred as a result of e-cigarette use in adolescents, and this new disease type is called EVALI (e-cigarettes or e-cigarette product use-associated lung injury) [6].Typical clinical symptoms of EVALI include: dyspnea, cough, chest pain ( respiratory system), nausea and vomiting (gastrointestinal system), fever, fatigue, weight loss and headache (systemic symptoms). It was later concluded that vitamin E acetate, a solvent in vaping, may have been an important causative agent in triggering this EVALI outbreak. However, the mechanism of acute lung injury induced by vitamin E acetate is still unclear, and some studies believe that it may be due to the decomposition of high-temperature heating to produce toxic substances such as olefins, benzene, or vinyl ketone . It should be noted that there may be more than one toxic substance in the composition of e-smoke that may cause lung injury, and the long-term hazards of e-cigarettes still need further attention and research [9].

 

5. Can vaping help traditional smokers quit smoking?

 

There has been conflicting evidence. The results of a long-term tracking, updated Cochran meta-analysis suggest that the use of e-cigarettes containing nicotine may have some benefit for smoking cessation compared with with other assisted cessation therapies or unassisted cessation .In a study published in the Chinese Journal of Clinical Physicians in 2015, “A survey of the use of e-cigarettes by a population of smokers in Beijing,” it was shown that, after the use of e-cigarettes by smokers, 8.3% had quit smoking and 47.1% smoked fewer cigarettes, suggesting that vaping can play a role in replacing traditional tobacco . However, the results of a meta-analysis about real-world studies published in The Lancet Respiratory Medicine in 2016 showed that the smoking cessation rate of people who used e-cigarettes was 28% lower than that of people who did not use e-cigarettes, i.e., the use of e-cigarettes in real-world settings does not help to reduce the prevalence of smoking (and may instead elevate the prevalence of smoking), and therefore the authors recommended that the use of e-cigarettes should not be promoted as an adjunctive aid to cessation of smoking before the evidence is sufficient . means of cessation.

 

6.  What do experts think about vaping at this stage?

 

Short-term use of e-cigarettes has been shown to stimulate oxidative stress damage, induce inflammation, and excite the sympathetic nerves. However, it is still unclear how long-term use of e-cigarettes affects the cardiovascular system, and current evidence suggests that e-cigarettes are not to be viewed as a safe product for the cardiovascular system. There is still a lack of sufficient evidence to support the effectiveness of vaping as an alternative to traditional tobacco in reducing traditional tobacco use or promoting long-term cessation. There is insufficient evidence related to achieving smoking cessation through the use of vaping in adults, including pregnant women, to determine the balance of benefits and harms. There is a lack of well-designed randomized clinical trials of e-cigarettes to confirm the efficacy or side effects of e-cigarettes for smoking cessation.

 

     7.Laws and regulations on vaping at this stage

 

In 2016, WHO recommended in the report presented at the seventh meeting of the World Health Organization Framework Convention on Tobacco Control that countries should adopt regulatory measures for vaping that prohibit or restrict the manufacture, importation, distribution, display, sale and use of e-cigarettes, in accordance with their respective laws and public health objectives. According to the 2020 data, 98 countries have enacted relevant legislation regulating the manufacture and sale of e-cigarettes, but with very different contents, with countries such as Japan and the United States regulating e-cigarettes as medicinal products, while South Korea, the United Kingdom, and the European Union regulating them as tobacco products; 29 countries banning e-cigarettes altogether; and another nine countries banning the use of nicotine vaping liquids; Most African countries and some populous countries including India, Indonesia, and Russia still lack effective regulation .

 

To protect minors from e-cigarettes, China’s State Tobacco Monopoly Administration (STMA) and State Administration for Market Supervision and Regulation (SAMSAR) have issued several circulars since 2018 to prohibit market players from selling e-cigarettes to minors, outlaw e-cigarettes’ online sales channels and forcibly withdraw e-cigarette advertisements published on the Internet, and further regulate the disguised sale of e-cigarettes, false advertisements, self-media dissemination, vending and business practices of age verification in brick-and-mortar stores, demonstrating our government’s determination to further strengthen the regulation of the e-cigarette market. In addition, China’s Hong Kong region has legislated a total ban on the use of vaping in 2018. The Hangzhou Municipal Government promulgated and implemented the “Regulations on Smoking Control in Public Places in Hangzhou” on January 1, 2019, which stipulates that vaping is prohibited in all public no-smoking places.

 

8. Our recommendations

 

• As the effectiveness of using vaping to assist smoking cessation is still controversial, smokers who are determined to quit smoking may consider using other WHO-recommended methods of cessation, such as nicotine patches, nicotine gum or nicotine sprays;

 

• For people who have not been exposed to tobacco and e-cigarettes, especially teenagers, the use of e-cigarettes should be strictly prohibited in accordance with national regulations to avoid long-term, as yet unspecified, harm
