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

Yes, there is some evidence that e-cigarettes may be harmful to health. There are many chemicals in e-cigarette vapor, and these can cause respiratory problems. Also, since nicotine is highly addictive, it can lead to dependence on e-cigarettes. So it's important to keep e-cigarettes away from children and teens.
