I've been hearing a lot of talk about the dangers of e-cigarettes. Is this really a problem?

Yes, it is. E-cigarettes contain nicotine, which is highly addictive and can be harmful to your health. They are also not regulated by the FDA like regular cigarettes, so there's no way to know what's in them. This means that you don't know how much nicotine you're getting, and it's possible that they could contain other harmful chemicals.
