Cochrane, an international authoritative medical organization: E-cigarettes have the effect of quitting smoking, and the effect replaces other treatment

On October 15, the Cochrane Collaboration (Cochrane Collaboration, hereinafter referred to as Cochrane), an internationally authoritative academic organization for evidence-based medicine, pointed out in its latest research overview that 50 majors were conducted on more than 10,000 adult smokers worldwide Studies have proved that e-cigarettes have the effect of smoking cessation, and the effect of continuous nicotine replacement therapy and other means.

Cochrane outlines that the effect of using nicotine e-cigarettes to quit smoking is better than using nicotine replacement therapy and e-cigarettes that exclude nicotine.

Professor Peter Hajek, co-author of the Cochrane review and director of the Tobacco Dependence Research Group at Queen Mary University of London, said: “This new overview of e-cigarettes shows that for many smokers, e-cigarettes are an effective tool for smoking cessation. It is also important to note that, For up to two years, none of these studies found any evidence that the use of electronic cigarettes caused harm to people.”

Compared with other treatments, nicotine e-cigarettes 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, that is, medicine based on consistent evidence, is different from traditional medicine based on empirical medicine. Key medical decisions should be based on the best scientific research evidence. Therefore, evidence-based medicine research will even conduct large-sample randomized controlled clinical trials, systematic reviews, meta-analysis, and then divide the level of evidence obtained according to standards, which is very rigorous.

In this study, Cochrane found 50 studies from 13 countries including the United States and the United Kingdom, involving 12,430 adult smokers. It has been shown that with the use of nicotine replacement therapy (such as nicotine patches, nicotine gum) or e-cigarette grades that exclude nicotine, more people use nicotine e-cigarettes to quit smoking for at least six months.


Reuters reported the results of Cochrane’s comprehensive research: “The review found: listed in gum or patch, e-cigarette is 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-cigarettes may successfully quit smoking; out of every 100 people who quit using nicotine replacement therapy or e-cigarettes that exclude nicotine, only 6 people can successfully quit Quit smoking, compared with other treatments, nicotine e-cigarettes have a higher rate of quitting.

This article, one of the authors of the overview, Professor Caitlin Notley of the University of East Anglia’s Norwich School of Medicine in the UK, said: “One of the most effective and widely used strategies to help people quit smoking is to eliminate smoking-related cravings. E-cigarettes and nicotine gums and stickers The agent is different. It mimics the experience of smoking and can provide smokers with nicotine, but does not expose users and others to the smoke of traditional tobacco.

The scientific consensus on e-cigarettes is that although e-cigarettes are not completely risk-free, they are far less harmful than cigarettes. “The Cochrane Tobacco Addiction Team” stated that “existing evidence shows that e-cigarettes and other nicotine substitutes increase the chances of successful smoking cessation.” Jamie Hartmann-Boyce said. She is also one of the main authors of the latest research.

Multiple studies confirm: 1.3 million people in the UK have successfully quit smoking with e-cigarettes

In fact, in addition to Cochrane, many authoritative medical academic organizations in the world have been converted into the relevant title of “e-cigarette smoking cessation better” at different levels.

Researchers from New York University in the United States have found that compared with users who have never used e-cigarettes, daily use of e-cigarettes can help smokers in the short-term (

As early as last year, an independent study by University College London (University College London) pointed out that e-cigarettes 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-cigarettes.

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

Regarding the public’s concern about the hazards of e-cigarettes, John Britton, Professor Emeritus of Respiratory Medicine at the University of Nottingham, UK, said: “The long-term impact on the safety of e-cigarettes requires long-term verification, but all evidence now shows that any long-term adverse effects of e-cigarettes are far Smaller than cigarettes.”

Before and after two years of tracking, no evidence was found that electronic cigarettes caused harm to the human body.
