More states are moving to raise the legal smoking age to 21

More states are moving to raise the legal smoking age to 21

For example, a 2016 study found e-cigs release far less formaldehyde than tobacco cigarettes. The U.S. research is the largest look yet at electronic cigarette users and it found e-cigarettes played a role in helping people quit.

The team also found that the United States population-wide smoking cessation rate increased significantly in the study period compared with previous years, with a 5.6% cessation rate in 2014-15 compared with 4.5% in 2010-11, corresponding to 350,000 additional smokers who quit.

The report, which surveyed 161,054 people in the USA across nearly 15 years, also found that substantially more people in the States are using e-cigarettes, and that this was linked to a "statistically significant increase in the smoking cessation rate at the population level".

E-cigarettes have been sold in the US since 2007.

"From 2014 to 2015, more e-cigarette users tried to quit cigarette smoking and succeeded in quitting than those who didn't use e-cigarettes", said lead researcher Shu-Hong Zhu, director of the university's Center for Research and Intervention in Tobacco Control.

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

But scientists remain divided over whether e-cigarettes are a "gateway" to smoking or a less harmful tool that helps smokers quit.

The study indicates e-cigarette users were more likely to quit for at least three months than non users (traditional cigarette smokers).

The BMJ study, titled "E-cigarette use and associated changes in population smoking cessation: evidence from USA current population surveys" was undertaken to find whether the dramatic increase in vaping between 2010-2014 had any connection with an overall drop in smoking in the US.

Glantz, in fact, previously authored a study finding that e-cigarettes may actually stymie efforts to quit smoking. Prior to e-cigs, the rate of smoking cessation among the entire population did not change significantly, despite the advocacy of pharmacotherapy.

How safe are e-cigarettes?

For the study, Zhu and colleagues collected data on more than 160,000 people who took part in five surveys between 2001 and 2015.

"With proper regulation, we could increase the potential of e-cigarettes to reduce the horrific toll of cigarette smoking in our society", he added. Among them, 38.2% of current smokers and 49.3% of recent quitters had tried e-cigarettes, indicating a higher incidence among quitters.

Research conducted by AACS showed that more than 50% of Australians supported the lifting of bans on nicotine products for e-cigarettes, and that 68% of smokers would try them if they were readily available and cheaper than cigarettes.
