E-cigarettes – A Therapy for Quitting Smoking

E-cigarettes – A Therapy for Quitting Smoking


The recognition that e-cigarettes help quit smoking should be based on science rather than prejudice.

On Oct.15, the international leading evidence-based medical academic organization, Coakeland (Cochrane Collaboration, Cochrane), noted in its latest research review that 50 professional studies of more than 10,000 adult smokers worldwide have demonstrated that e-cigarettes have a smoking cessation effect and are superior to nicotine replacement therapy.

Cochrane review points out that using nicotine e-cigarettes to quit smoking is better than using nicotine replacement therapy and nicotine-free e-cigarettes.

Whether e-cigarettes can quit smoking effectively has been a topic of great concern. However, because the systematic scientific research of electronic cigarette in China is not complete, it is difficult for the public to know the accurate research results in time. This has led to the smoking cessation effect of e-cigarettes being ignored by many people, and some experts even deny the smoking cessation effect of e-cigarettes based on prejudice rather than science.

The new review of e-cigarettes suggests that for many smokers, e-cigarettes are an effective tool for smoking cessation, says Peter Hajek professor, Cochrane review author and director of the tobacco dependence research group at Queen Mary University in London. It should also be noted that, over a period of two years, none of these studies has found any evidence that the use of e-cigarettes can cause harm to people.

Nicotine e-cigarettes are more likely to quit smoking than other treatments

Cochrane, founded in 1993, is a non-profit organization named to commemorate the founder Archie bALD L.Cochrane of evidence-based medicine. It is also the most authoritative independent evidence-based medicine academic organization in the world. So far, there are more than 37000 volunteers and more than 170 countries.
<unk1> The so-called evidence-based medicine, that is, the medicine following evidence, is different from the traditional medicine based on empirical medicine, and emphasizes that medical decision-making should be based on the best scientific research evidence. Therefore, evidence-based medicine research will not only carry out large sample randomized controlled clinical trials, systematic evaluation, meta-analysis, but also according to the standard classification of the level of evidence, very rigorous.

A total of 50 studies from 13 countries, including the United States and the United Kingdom, involving 12,430 adult smokers, were found in Cochrane study. Conclusions show that more people use nicotine e-cigarettes to quit smoking for at least six months than use nicotine replacement therapy (such as nicotine patches, nicotine gum) or nicotine-free e-cigarettes.

E-cigarettes quit smoking more effectively than chewing gum or patches, the review Cochrane Reuters reported

Specifically, in absolute terms ,10 out of every 100 people who quit smoking using nicotine e-cigarettes are likely to succeed; only 6 out of every 100 people who quit smoking using nicotine replacement therapy or nicotine-free e-cigarettes can successfully quit smoking, and nicotine e-cigarette smoking cessation rates are higher than other treatments.

“One of the most effective and widely used strategies to help people stop smoking is to eliminate smoking-related cravings. Unlike nicotine gum and patches, e-cigarettes mimic the experience of smoking and provide nicotine to smokers, but do not expose users and others to traditional tobacco smoke ,” said Caitlin Notley Norwich School of Medicine, a professor at the University of East Anglia. ”

“There is evidence that e-cigarettes increase the chances of quitting successfully compared with other nicotine substitutes. The scientific consensus on e-cigarettes is that although e-cigarettes are not completely risk-free, they are far less harmful than cigarettes. “said Jamie Hartmann-Boy ce of the Cochrane Tobacco Addiction Group. She is also one of the lead authors of this review.

A number of studies have shown that 1.3 million people in the UK have successfully quit smoking with e-cigarettes

As a matter of fact, in addition to Cochrane, in recent years, many authoritative medical academic organizations have reached the conclusion that “e-cigarette smoking cessation is more effective” to varying degrees.

A study by New York University researchers found that daily use of e-cigarettes was 2-4 times more likely to help smokers quit in the short-term (<1 year) and long-term (1 year) than users who had never used e-cigarettes, while researchers at Vienna Medical University in Austria pointed out that the proportion of smokers who used e-cigarettes was 1.69 times higher than those who received nicotine replacement therapy. (Both findings are published in the leading industry journal Nicotine Tobacco Research)

As early as last year, an independent study at University College London (University College London) found that e-cigarettes help 50,000 to 70,000 cigarette users quit smoking each year. At least 1.3 million people have been given up completely because of e-cigarettes, according to a new report by the Department of Public Health.

E-cigarettes help at least 50,000 British smokers quit smoking successfully a year, according to a study published by University College London (University College London) in the internationally renowned academic journal Addiction.

As for the public’s concern about the harm of e-cigarettes, John Britton, an honorary professor of respiratory medicine at the University of Nottingham, said: the long-term impact of e-cigarette safety will take many years to verify, but now all the evidence shows that any long-term adverse effects of e-cigarettes are much smaller than cigarettes. ”

Cochrane research supports his view to some extent. During a two-year follow-up period, no evidence of harm caused by e-cigarettes was found.
