<human>: I've been hearing a lot of talk about the dangers of e-cigarettes. Are they as bad as people say?
<bot>: Well, I’ve never used an e-cigarette, but from what I think I understand, they deliver nicotine in aerosol form, which is inhaled by the user. Nicotine is addictive and can be harmful to health if consumed in large amounts over time. So it seems like there could be some potential risks associated with using them.
