Whether electronic vapor cigarettes can effectively quit smoking?

2021-01-20

"Whether electronic vapor cigarettes can effectively quit smoking" has always been a topic of concern. 


However, due to the incomplete systematic scientific research on electronic vapor cigarettes in China, it is difficult for the public to know accurate research results in time. This has caused the smoking cessation effect of e cigs to be ignored by many people. Some experts even rejected the smoking cessation effect of e cigs based on prejudice rather than science.

 

Professor Peter Hajek, a special author of the Cochrane review and director of the Tobacco Dependence Research Group at Queen Mary University of London, said: "This new review on e cigs shows that for many smokers, e cigs are an effective tool for smoking cessation. It is also important to note that For up to two years, these studies have not found any evidence that the use of electronic vapor cigarettes will cause harm to people."

 

   Compared with other treatments, nicotine e cigs have a higher smoking cessation rate.


Founded in 1993, Cochrane is a non-profit organization named in memory of Archiebald L. Cochrane, the founder of evidence-based medicine. It is also the most authoritative independent evidence-based medical academic organization in the world. So far, it has more than 37,000 volunteers in more than 170 countries. One.

 

   The so-called evidence-based medicine refers to medicine that follows evidence. It is different from traditional medicine based on empirical medicine. It emphasizes that medical decision-making should be based on the best scientific research evidence. Therefore, evidence-based medicine research will not only conduct large-sample randomized controlled clinical trials, systematic reviews, and meta-analysis, but also divide the level of evidence obtained according to standards, which is very rigorous.

 

   In this study, Cochrane discovered 50 studies from 13 countries including the United States and the United Kingdom, involving 12,430 adult smokers. Conclusions show that more people use nicotine e cigs to quit smoking for at least six months compared to using nicotine replacement therapy (such as nicotine patches, nicotine gum) or nicotine-free e cigs.

 

Reuters reported that Cochrane reviewed the research results: "The review found: Compared with chewing gum or patches, e cigs are more effective in quitting smoking."

 

Specific to the data, calculated in absolute terms, 10 out of every 100 people who quit smoking using nicotine e cigs are likely to successfully quit smoking; out of every 100 people who quit using nicotine replacement therapy or e cigs without nicotine, only 6 people can quit smoking. Compared with other treatments, nicotine e cigs have a higher rate of quitting smoking.

 

In response, Caitlin Notley, one of the authors of the review and a professor at the University of East Anglia’s Norwich School of Medicine in the United Kingdom, said: “One of the most effective and widely used strategies to help people quit smoking is to eliminate smoking-related cravings. e cigs and nicotine gums and stickers. The agent is different. It mimics the experience of smoking and can provide smokers with nicotine, but will not expose users and others to the smoke of traditional tobacco."

 

"Existing evidence shows that compared to other nicotine substitutes, e cigs increase the chances of successfully quitting smoking. The scientific consensus on e cigs is that although e cigs are not completely risk-free, they are far less harmful than cigarettes." Cochrane Tobacco Addiction Group Jamie Hartmann-Boyce said. She is also one of the main authors of this research review.

 

  Multiple research evidence: 1.3 million people in the UK have successfully quit smoking with e cigs

 

   In fact, in addition to Cochrane, in recent years, many authoritative medical academic organizations in the world have come to the conclusion that "e cigs are better for smoking cessation" to varying degrees.

 

Researchers from New York University in the United States have found that compared with users who have never used e cigs, daily use of e cigs can help smokers to quit smoking in the short-term (<1 year) and long-term (1+ years) 2- 4 times; a researcher from the Medical University of Vienna in Austria pointed out that compared with smokers receiving nicotine replacement therapy, the proportion of using e cigs to quit smoking was 1.69 times higher. (The above two research conclusions were published in the industry authoritative journal "Nicotine Tobacco Research")

 

   As early as last year, an independent study by University College London pointed out that e cigs help 50,000 to 70,000 cigarette users in the UK to quit smoking every year. The latest report from the Department of Public Health of the United Kingdom also shows that at least 1.3 million people have quit cigarettes completely because of e cigs.

 

The research results published by University College London in the internationally renowned academic journal Addiction pointed out that e cigs have helped at least 50,000 British smokers to quit smoking successfully a year.

 

As for the public's concern about the hazards of e cigs, John Britton, Professor Emeritus of Respiratory Medicine at the University of Nottingham in the UK, said: "The long-term impact on the safety of e cigs needs to be verified for many years, but all evidence now shows that any long-term adverse effects of e cigs are far Smaller than cigarettes."

 

   Cochrane's research corroborated his views to a certain extent. During the two-year follow-up period, no evidence was found that electronic vapor cigarettes caused harm to the human body.
