According to a research team of ten scientists, up to 6.6 million cigarette smokers will live substantially longer if cigarette smoking is replaced by vaping over a ten-year period.
Dr. David Abrams and Dr. Raymond Niaura, professors of social and behavioral sciences at New York University College of Global Public Health, were part of this research team and were co-authors of the new study, “How do we determine the impact of e-cigarettes on cigarette smoking cessation or reduction? Review and recommendations for answering the research question with scientific rigor.” This study was recently published in the journal Tobacco Control and led by Georgetown Lombardi Cancer Center. The aim of the study was to propose a hierarchy of methodological criteria to consider when determining whether a study provides sufficient information to answer the question of whether e-cigarettes can facilitate cigarette smoking cessation or reduction.
For the study, the team of researchers looked at such variables as harm from e-cigarettes, and amount of youth uptake, and the rate of cessation among others. Based on different scenarios regarding the relative harms of e-cigarettes compared to cigarettes as well as differences in the timing of smoking initiation, cessation and switching, the authors were able to make two projections. The more “pessimistic” scenario finds 1.6 million of these former cigarette smokers will have a combined 20.8 million more years of life, while the more “optimistic” scenario calculates 6.6 million nicotine users who switch from cigarettes to e-cigarettes will live 86.7 more life years.
