<human>: I've heard that e-cigarettes are healthier than regular cigarettes. Is this true?
<bot>: Yes, it is true that e-cigarettes are generally considered to be a safer alternative to traditional cigarettes. They do not contain the same amount of harmful chemicals as regular cigarettes and they may also help reduce nicotine cravings. However, there is still much more research needed to understand the long-term health effects of using e-cigarettes.
