E-cigarettes have a smoking cessation effect

Time： 2021-12-29

Five reports in seven years, the international authoritative medical organization Cochran has always insisted that e-cigarettes have smoking cessation effects

Recently, the international authoritative academic organization of evidence-based medicine-the Cochrane Collaboration (Cochrane) in its latest "review report" pointed out that 61 professional studies conducted on 16,759 adult smokers around the world proved that , E-cigarette has the effect of smoking cessation, and the effect is better than nicotine replacement therapy, nicotine-free e-cigarette and other methods.

Founded in 1993, Cochrane is the most authoritative independent evidence-based medical academic organization in the world. Evidence-based medicine 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 evaluations, and meta-analysis, but also divide the level of evidence obtained according to standards, which is very rigorous.

At present, many smokers choose to use e-cigarettes to reduce smoking or quit smoking, but some public health organizations and policy makers have doubts about the effectiveness and safety of e-cigarettes to quit smoking.

To this end, the members of the Cochrane Tobacco Tumors Group have been updating the summary report from time to time based on the research of international authoritative institutions since 2012, so as to provide decision makers in various countries with the fastest and most comprehensive e-cigarette information to determine whether e-cigarettes can be Whether to help people quit smoking, and whether it is safe to use e-cigarettes.

The main authors of this report include 12 experts and scholars, including senior researcher of the University of Oxford Evidence-Based Medicine Center, director of the Evidence-Based Medicine PhD Program, and Jamie Hartmann-Boyce of Cochrane Tobacco Group.

The report concludes that there is evidence that, compared with nicotine substitution and nicotine-free e-cigarettes, more people have successfully quit smoking for more than six months after using nicotine e-cigarettes.

The report pointed out that the effect of using nicotine e-cigarettes to quit smoking is better than other methods.

Specific to the data, for every 100 people who use nicotine e-cigarettes, 9 to 14 people can successfully quit smoking; using nicotine replacement method, 6 people can quit smoking, and using nicotine-free e-cigarettes, 7 people can quit smoking; if you don't use smoking cessation methods Intervention, direct smoking cessation, only 4 out of every 100 people can quit smoking successfully.

The report also highlighted that after referring to a number of tests, no evidence that electronic cigarettes are harmful to humans has been found.

The author pointed out that some people who use nicotine e-cigarettes may experience discomfort, such as mouth and throat irritation, and cough, but as people continue to use nicotine e-cigarettes, these effects will also decrease over time.

Throughout many international studies, in addition to Cochrane, many authoritative medical academic organizations have also drawn similar conclusions. For example, in 2019, an independent study by University College London pointed out that 50,000 to 70,000 smokers in the UK use e-cigarettes to quit smoking every year.

Since the establishment of the project in 2012, this is the fifth time that Cochrane has updated its summary report related to the effect of e-cigarette smoking. Since the first update on December 17, 2014, all reports indicate that e-cigarettes have smoking cessation effects, and The effect is due to other smoking cessation methods.

As a representative of an independent medical academic organization, Cochrane has insisted on updating the review report for many years, which is undoubtedly sending a signal to policymakers of various countries that "e-cigarettes can be promoted as a smoking cessation tool". The United Kingdom, which has always adhered to evidence-based decision-making strategies, has become one of the countries with the fastest decline in smoking rates in the world because of the promotion of e-cigarettes as a tobacco control tool based on scientific research.
