Vapeboss – A replication of an in vitro study published in Wiley Analytical Science found that vape vapor does not produce negative effects on cells, unlike cigarette smoke which causes damage to blood vessels.

The study, titled "Comparative assessment of electronic nicotine delivery systems aerosol and cigarette smoke on endothelial cell migration: The Replica Project," replicated previous studies in comparing the in vitro effects of e-cigarette vapor versus cigarette smoke.

Consistent with the findings of the initial study, the research team found that aerosols from vape products caused significantly less cell damage than cigarette smoke. They explained that cigarette smoke reduced endothelial wound healing ability, even at low concentrations (12.5%), while vape vapor did not show similar effects on endothelial cells, even at concentrations of 80-100%.

“In conclusion, our research further reinforces the importance of ECs and heated tobacco products as a possible harm reduction strategy for the development of cardiovascular disease in smokers,” the study abstract concluded.

Meanwhile, another study that analyzed data from the Population Assessment of Tobacco & Health (PATH) study found no association between the use of electronic nicotine delivery systems (ENDS) and an increased risk of cardiovascular disease.

The study, titled "Longitudinal associations between exclusive and dual use of electronic nicotine delivery systems and dual use of electronic nicotine delivery systems and cigarettes and self-reported incident diagnosed cardiovascular disease among adults," currently analyzed waves 1-5 of the PATH Study (2013-2019).

The research team looked for individually reported incident risks with diagnoses of myocardial infarction (280 cases) and stroke (186 cases) as well as the likelihood of ENDS or cigarette use among adults aged 40 and over.

The collected data found that exclusive cigarette use increased the risk of myocardial infarction and stroke, while ENDS use and non-smokers did not cause these diseases.
