This blog considers recent studies in which the biomarker levels in e-cigarette users (vapers) are compared to those from tobacco smokers.
The results are highly variable but all suggest lower levels of risk to vapers relative to tobacco smokers. Yet as the situation with vaping is very dynamic (new products, changing ways people vape) and there is no evidence yet about long-term effects of e-cigarette use on health outcomes, a lot more future research will be needed to get a reasonable understanding of the relative harms.
The blog is written by Prof Nick Wilson, Dr Coral Gartner and Prof Richard Edwards.
