US: Vaping A Life Saver

Up to 6.6 million US cigarette smokers will live substantially longer than they otherwise would if cigarette smoking is replaced by vaping over a 10-year period, according to a Medical Xpress story citing research published in the journal Tobacco Control.

The study, by a research team led by investigators from the Georgetown Lombardi Cancer Center, Washington, DC, looked at a strategy of switching cigarette smokers to e-cigarette use in the US to accelerate tobacco control progress.

The team considered an optimistic and a pessimistic scenario, ¡®differing in terms of the relative harms of e-cigarettes compared with cigarettes and the impact on overall initiation, cessation and switching¡¯.

It found that, compared with the Status Quo, replacement of cigarette by e-cigarette use over a 10-year period yielded 6.6?million fewer premature deaths with 86.7?million fewer life years lost under the optimistic scenario. ¡®Under the pessimistic scenario, 1.6?million premature deaths are averted with 20.8?million fewer life years lost,¡¯ the team found. ¡®The largest gains are among younger cohorts, with a 0.5 gain in average life expectancy projected for the age 15 years cohort in 2016.¡¯

The team said that the tobacco control community had been divided regarding the role of e-cigarettes in tobacco control.

¡®Our projections show that a strategy of replacing cigarette smoking with vaping would yield substantial life year gains, even under pessimistic assumptions regarding cessation, initiation and relative harm.¡¯  Enditem
