Exploring whether e-cigarette can help to quit smoking

The latest research shows that e-cigarettes can help smokers quit smoking, and in the short to medium term will not cause side effects.

The study came from the medical research organization The Cochrane CollaboraTIon, who claimed to have found evidence.

E-cigarettes are becoming more and more popular because of fashion and pollution-free. In the United States alone, about 2 million smokers smoke electronic cigarettes. At the same time, e-cigarettes are highly controversial, and people are questioning its safety, fearing it is harmful to health; and it may also adversely affect smoking cessation services.

"From the current limited information we can know that electronic cigarettes containing nicotine can help smokers quit," Jamie Hartmann-Boyce said. She is from Oxford University and is a co-author of the Cochrane cessation study.

"From the short- to medium-term data, e-cigarettes do not induce serious side effects," she added.

This echoes the results of the first study that Cochran did in 2014.

After two randomized controlled trials of more than 660 people, they found that nicotine-containing e-cigarettes can increase the chances of smokers quit smoking: 9% of smokers who smoke nicotine-containing e-cigarettes can quit for at least 6 months; Only 4% of smokers who smoke nicotine-free e-cigarettes can do it. However, whether e-cigarettes are more effective than other methods (such as nicotine patches), we still don't know.

Cochran has conducted 11 studies, but no randomized controlled trials have been conducted. Cochrane said that the use of e-cigarettes for more than two years did not cause serious side effects.

"The really good news from this research is that more relevant research is underway," Hartmann-Boyce said. “I hope that in the next few years, there will be more research results to support our conclusions.”

The study, consistent with a study published in the British Medical Journal, argues that e-cigarettes can increase the success rate of smokers' quitting.

The British Medical Journal study selected 170,490 people over the age of 16 in the UK, 23% of whom used to smoke and 21% were still smoking. The study also analyzed data from the NHS (National Health Service System) cessation service, which included more than 8 million smokers.

“We estimate that about 580 of every 10,000 smokers who use e-cigarettes to quit smoking will quit smoking. These people can't stop smoking by other means,” said Robert West, co-author of the study and London. Professor of University Health Psychology.

Researchers estimate that in 2015 alone, e-cigarettes helped 18,000 smokers successfully quit. Moreover, they believe that e-cigarettes may become an item that reduces nicotine replacement therapy.

However, they added that there is no clear evidence that e-cigarettes can encourage smokers to quit, and its impact on nicotine replacement therapy and smoking cessation services is currently not estimated, although the benefits of the cessation service industry have some degree due to e-cigarettes. Sliding down.

“There is no evidence that e-cigarettes affect people’s chances of quitting smoking, and it can only increase the success rate of smokers who want to quit,” West said.

John Britton, director of the University of Nottingham's Tobacco and Alcohol Research Center, said demand for smoking cessation services is declining due to a variety of factors, including cuts in media campaigns and the inclusion of smoking cessation services in local government management. “The smoking cessation service has been drastically reduced due to changes in public health service funding,” he said.

At the same time, Britton also reminded that Cochran's research is based on early e-cigarettes (with very little nicotine), and he believes that the latest development of e-cigarettes can improve smoking cessation efficiency.

"Smoking is harmful to health, and there is no doubt about this," he said. "If you can't quit smoking, but you can accept another form of nicotine, that's fine."

“The end result we want to see is that smokers try to use e-cigarettes and then quit smoking as quickly as possible.”

Deborah Arnott, CEO of the Smoking and Health Charity Action, said: "Overall, Cochrane and the British Medical Journal further confirm that the use of e-cigarettes does not hinder smoking cessation. Indeed, according to English data, electronics The use of smoke is linked to the success rate of smokers' quitting."
