A 2024 study compared traditional cigarettes, nicotine vapes, and nicotine-free vapes. All three impaired vascular function. Nicotine vapes had the worst effect, but nicotine-free ones weren’t far behind. The takeaway? The base ingredients and flavorings themselves are harmful.

Dr. Marianna Nabbout, one of the researchers, warned that if a single vape session can immediately impact your blood vessels, long-term use could lead to serious vascular disease.

Worse still, vaping is drawing in people—especially youth—who might never have smoked otherwise. According to Johns Hopkins, over 2 million U.S. students used e-cigarettes in 2021, with most choosing flavored ones.

If you thought vaping was harmless, this study is a wake-up call.
