A study conducted by a research team from Georgetown Lombardi Comprehensive Cancer Center has concluded that up to 6.6 million cigarette smokers will live longer if they make the switch from smoking tobacco to vaping, over a 10 year period. Cigarette smokers could live 86.7 million years longer in total, if policies and guidelines are implemented to aid smokers to move to vaping.

The study, published in the Tobacco Control Journal, is the first of its kind, modelling public health changes if cigarette smokers switched to electronic cigarettes.

The study’s lead author David Levy said:

“The study supports a policy strategy that encourages replacing cigarette smoking with vaping to yield substantial life year gains”

Funded by The National Institutes of Health, the study involved scientists and researchers from multiple universities. 10 investigators looked at a range of variables including potential harm from vaping, youth uptake and the rate of current cessation.

The outcome was two projections, one ‘pessimistic’ and the other ‘optimistic’.

In the ‘pessimistic’ scenario, it was found that 1.6 million smokers could have a combined 20.8 million more years of life. The ‘optimistic’ scenario found that 6.6 million smokers could live for a combined 86.7 million years, if they made the switch to electronic cigarettes.

David Levy went on to say:

“In addition, there would be tremendous health benefits including reduced disease disability to smokers, reduced pain and suffering, and reduced exposure to second hand smoke,” 

Even the gloomiest analysis shows a significant gain in years of life if nicotine is obtained from vaping instead of much more deadly amount of toxicants inhaled with cigarette smoke.”

The hope is that this study may help government bodies find a solution to end cigarette smoking for good.

“Old policies need to be supplemented with policies that encourage substituting e-cigarettes for the far more deadly cigarettes,” Levy says.

“Together, these policies as well as regulating the content of cigarettes have the potential to drastically reduce the massive harms from smoking cigarettes.”
