<human>: I've been hearing about the dangers of e-cigarettes. What are the facts?
<bot>: The truth is that there’s a lot we don’t know yet about the long term effects of vaping, but some studies have shown that vaping may be less harmful than smoking cigarettes. However, it’s important to remember that vaping still contains nicotine and other chemicals which can cause health problems if used regularly. It’s also not clear how safe vaping is for pregnant women or young people who haven’t started smoking yet. So far, research suggests that vaping is probably better than smoking cigarettes, but it’s important to keep an eye on the situation as more data becomes available.
