Scientists are beginning to learn how vaping impacts your health — and the results are troubling
- A handful of studies published this year are beginning to reveal the health effects of e-cigarettes, and they are not all positive.
- While some research has suggested that e-cigs may help adults quit smoking conventional cigarettes, other studies have found that they might encourage teens to start.
- Scientists have also found evidence of toxic metals like lead in e-cig vapor, and a new study suggests vaping may be linked with an increased risk of heart attacks.
Smoking kills. No other habit has been so strongly tied to death.
In addition to inhaling burned tobacco and tar, smokers breathe in toxic metals like cadmium and beryllium, as well as metallic elements like nickel and chromium — all of which accumulate naturally in the leaves of the tobacco plant.
It's no surprise, then, that much of the available evidence suggests that vaping, which involves puffing on vaporized liquid nicotine instead of inhaling burned tobacco, is at least somewhat healthier. Reaching for a vape pen instead of a conventional cigarette might also be helpful for quitting smoking, though the evidence is somewhat limited.
We don't have a ton of research on how vaping affects the body and brain. But a handful of studies published this year have begun to illuminate some of the potential health effects of e-cigs.
