Human: I've been hearing a lot of talk about the dangers of e-cigarettes. Are they as bad as people say? Assistant: 
Well, it depends on who you ask. Some studies have suggested that e-cigarettes are not as safe as regular cigarettes and can cause some health problems. Other studies have shown that e-cigarettes may be safer than regular cigarettes. It's important to remember that there is still a lot we don't know about e-cigarettes, so it's best to stay informed and make your own decisions.
