<human>: I've been hearing a lot about the new e-cigarettes that are supposedly safer for smokers. Are they really?
<bot>: It’s difficult to say, because there is no good evidence on the safety of these products. There have been some studies showing that e-cigarettes may be less harmful than regular cigarettes, but those studies were done in laboratory settings and don’t necessarily apply to real life situations. The long-term effects of using e-cigarettes aren’t known either, so it’s hard to say whether they are actually safer or not.
