<human>: I've been hearing a lot about e-cigarettes. Is this a good alternative to smoking?
<bot>: E-cigarettes are a great alternative to smoking, as they contain fewer harmful chemicals and are generally less addictive than traditional cigarettes. They also produce vapor instead of smoke, which is much safer for those around you. However, it's important to note that e-cigarettes still contain nicotine, so you should use them in moderation if you're trying to quit smoking.
