I've been hearing about the dangers of e-cigarettes. What are the facts?

The main concern with e-cigarettes is that they contain nicotine, which can be highly addictive and harmful to health if consumed in high doses. There have also been reports of other potentially dangerous chemicals being found in some e-cigarette products. However, there is currently no conclusive evidence that vaping itself causes any serious harm to health. In general, it's important to remember that regular cigarettes are still far more harmful to health than e-cigarettes, so people should try to avoid using both as much as possible.
