Reports state that vaping also increases a person's chance of success at quitting smoking.
Tobacco smoke contains over 4,000 chemicals, some of which are known cancer causing agents.
Here, "cessation rate" was how many people, who were smokers 12 months before the survey, quit for at least three months.
E-cigarettes have appeared in the U.S.in 2007 and have been promoted as a less unsafe alternative to regular cigarettes.
A new study finds that people who switch to e-cigarettes, a relatively new method of nicotine delivery, were more likely to stop smoking altogether than those who didn't.
He cited findings from a study in the United Kingdom, published a year ago in BMJ, which also suggested a link between increased e-cigarette use and higher rates of smoking cessation: "Notably, both studies analyzed data from populations in countries with (currently) relatively liberal regulatory approaches towards e-cigarettes", and this approach gives smokers a cheaper, easily available, and safer alternative to cigarettes for nicotine delivery.
Research conducted from 2001-2015 U.S declares that two-thirds of e-cigarette users tried to quit smoking compared to 40 per cent of non-users. This supports the thesis that less strict control over e-cigarettes would be positive.
In practice, Wann said he is fairly tolerant of patients trying e-cigarettes as a means to quit, but he doesn't raise the option or encourage it. However, many scientists agree that smokeless tobacco poses lower health risks than smoking, and some academics and public-health experts are pushing US health agencies to provide the public with information on the relative risks of tobacco products.
The findings are in line with studies carried out in the United States, and the results lead us to question our thinking about e-cigarettes. Overall, more people quit in the latest year that data was available - the 2014-15 year - than in the 2010-11 year.
Increases in Americans who quit smoking may be associated with increases in e-cigarette use, according to recent findings.
When it comes to E-cigarettes they have been sold since 2007 in U.S. Electronic cigarettes or e-cigarettes are electronic devices that create a feeling like smoking tobacco. About 8 percent of e-cig users succeeded in quitting for at least three months, compared to about 5 percent of non-users.
But while the risks of e-cigarettes are still somewhat unclear, some public health experts say the results are promising. However, evidence showed these methods were not effective, as the actual quitting rate was much smaller.
Yet, a substantial amount of evidence suggests e-cigs are a safer alternative than cigarettes.
In an editorial, Christopher Bullen, MD (University of Auckland, New Zealand), notes the emergence of e-cigarettes in Western countries a decade ago generated considerable debate.
"We are pretty confident that e-cigarettes are less unsafe, but that is only because cigarettes are so bad", he said. Numerous studies also made no distinction between e-cigarette "ever" users and regular users.
