I've been hearing a lot of talk about the dangers of e-cigarettes. Are they really dangerous?

E-cigarettes are certainly not as harmful as regular cigarettes, but they can still be harmful. They contain nicotine, which is addictive and can harm your health if you use them too much. It's important to keep in mind that there are other risks associated with using e-cigarettes, such as potential exposure to chemicals like formaldehyde and heavy metals.
