When e-cigarettes first appeared around 2010, they were hailed as a breakthrough: nicotine delivery without the toxic tar and combustion byproducts of traditional cigarettes. Public health bodies cautiously endorsed them as a tool for adult smokers to quit, often citing early claims that vaping was 95% less harmful than smoking. More than a decade later, with millions now vaping regularly, the picture is less clear.
A recent study, published in the American Journal of Physiology – Heart and Circulatory Physiology, found that people who vape or smoke have nearly 50% higher odds of elevated blood pressure compared to non-users. This isn’t proof that vaping directly causes high blood pressure – other factors such as diet or exercise could play a role – but it adds to a growing body of evidence that vaping’s early reputation for safety deserves a harder look.
