In this scenario, they calculate, replacement of cigarettes by e-cigarettes over a 10-year period would lead to 6.6 million fewer premature deaths with 86.7 million fewer years of life lost. The models used in the study were developed by Levy and co-authors Rafael Meza, PhD, from the University of MI and Theodore R. Holford, PhD, from Yale University.
Writing in an editorial that was published alongside the new study, Marita Hefler, a public health researcher at Menzies School of Health Research in Australia, said that "the health gains modelled [in the new study] show that even in a pessimistic scenario", rapidly phasing out regular cigarettes could result in significant public health gains.
Even in this model, researchers found beneficial results. In that case, 1.6 million lives would be spared by the year 2100.
David Levy, a lead researcher and professor of oncology at Georgetown Lombardi Comprehensive Cancer Center, said that "old policies need to be supplemented with policies that encourage substituting e-cigarettes for the far more deadly cigarettes".
The study, funded by National Institutes of Health, compares a status-quo scenario with a scenario in which e-cigs and vaporizers largely replace traditional cigarettes over 10 years. As of 2016, he has published more than 40 studies and articles in global peer-reviewed scientific journals about smoking, tobacco harm reduction and e-cigarettes.
E-cigarettes carry 5 percent of the health risk of tobacco cigarettes.
"This FCTC provision is a recognition that harm-reduction measures can be considered for tobacco control", Bravo said.
"Now, we have some of the most respected American researchers in the field of tobacco control explaining in detail how vaping can and will save lives", Conley said.
Starting next month, major USA cigarette companies will publish a series of statements about the health risks of smoking.
Fire Prevention Day to bring local organizations together to promote children's health
In a typical home fire, you may have as little as one to two minutes to escape safely from the time the smoke alarm sounds. "Also during Fire Prevention Week we'll actually go to some of the schools".
For long-term smokers, 2 out of 3 will likely die prematurely due to ailments from smoking. In other words, switching from cigarettes to e-cigarettes could extend the lives of smokers, compared with if they were to continue smoking traditional tobacco cigarettes.
That's why some argue that e-cigarettes are generally a good thing, if it means less cigarettes (again, safer, not safe). Because of the dates of the survey, it includes the more current types of e-cigarettes that are more effective at delivering nicotine.
People would quit e-cigarettes at about the same rate they quit tobacco.
Anti-smoking advocates, including the American Lung Association, have been particularly critical of e-cigarettes as a gateway for kids and teens to take up nicotine.
However, the vapor-emitting, battery-powered devices remain unregulated by the U.S. Food and Drug Administration.
Levy says the debate over flavorings is more complicated than that.
'The residual prevalence of cigarette smokers will depend on the potency of policies directed at cigarette use, ' the study says, but acknowledges that the same will be true of e-cigarette use. But Levy notes there are important nuances in the data that affect success.
In an optimistic scenario, the benefits are significantly more robust.
Cigarette smoking would decline to 5 percent of the USA population as e-cigarettes become the more popular option, down from the current 16 percent.
