That fruity, nicotine-free vape might seem harmless, but medical experts warn it could be affecting your health in ways you don’t realize. While removing nicotine eliminates addiction risks, other concerning elements remain in e-cigarette vapor that may harm your lungs and blood vessels over time.
The real issue lies in what happens when e-liquids heat up. Harmless-seeming flavorings break down into respiratory irritants like diacetyl (linked to “popcorn lung”) and benzaldehyde.
Heating coils can release microscopic metal particles, while the vapor itself contains fine particulates that may cause inflammation. Most troubling? A 2024 study found nicotine-free vaping still significantly reduced blood vessel function after just one use – a warning sign for potential long-term cardiovascular effects.
