E-cigarettes help smokers quit

27 Juillet 2017

They said in the paper: 'This study, based on the largest representative sample of e-cigarette users to date, provides a strong case that e-cigarette use was associated with an increase in smoking cessation at the population level.

Kenneth Warner, a professor of public health at the University of MI, welcomed the findings.

AACS CEO Jeff Rogut has argued that while the ban remains in place, e-cigarette users must source their nicotine online without quality assurance.

However, there have been warnings that the long-term effects of vaping devices are still unknown.

Among the 2014 survey respondents, 22,548 were current smokers and 2,136 were recent quitters.

The study identified that the cessation rate for smokers who did not use e-cigarettes in 2014-15 was "statistically indistinguishable" from the rate in previous years.

The overall population quit rate for 2014-15 was significantly higher than that for 2010-11, up from 4.5% to 5.6%, and higher than those for all other survey years. The percentage rise of 1.1% translates to approximately 350,000 smokers who quit smoking over a year explain researchers and this is not a small number. This is the first statistically significant increase observed in population smoking cessation among U.S. adults in the past 15 years.

"Other interventions that occurred concurrently, such as a national campaign showing evocative ads that highlight the serious health consequences of tobacco use and state tobacco control efforts, no doubt played a role", Zhu said in the release. There are several aids on the market available for those who want to stop smoking but until now, e-cigarettes were not considered to be of help with that.

A team of researchers, led by Professor Shu-Hong Zhu at the University of California, set out to examine whether the increase in use of e-cigarettes in the United States of America, was associated with a change in overall smoking cessation rate at the population level.

Today's study didn't address whether e-cigs are luring people who would otherwise be nonsmokers. Most e-cigarettes heat a liquid nicotine solution which then turns into vapor.

The research, conducted by a collaboration between the universities of Stirling, St Andrews and Edinburgh, and ScotCen, focused on pupils at four secondary schools.

The 2016 survey found that 40.4% of those who had tried an e-cigarette in the initial 2015 survey went on to smoke a cigarette in the following 12 months, compared to only 12.8% of young people who had not tried an e-cigarette.

But scientists remain divided over whether e-cigarettes are a "gateway" to smoking or a less harmful tool that helps smokers quit. About 8 percent of e-cig users succeeded in quitting for at least three months, compared to about 5 percent of non-users. E cigarettes do not produce tar or carbon monoxide like traditional cigarettes.

The body would regularly update its evidence base on e-cigarettes and include the advice in all quit smoking campaign messaging, added the plan, it said.

In the United States, public health organizations have focused nearly exclusively on the potential adverse consequences of e-cigarettes for kids, to the detriment of the health of adults who might benefit from a more positive take on e-cigarettes, he said.

Mr Hajek said: 'It's absolutely clear that e-cigarettes help smokers replace cigarettes'.

"It is remarkable, considering that this is the kind of data pattern that has been predicted but not observed at the population level for cessation medication, such as nicotine replacement therapy and varenicline", the report stated.
