<human>: I've been hearing about the dangers of e-cigarettes, but I don't know much about them. Can you tell me more about them?
<bot>: E-cigarettes are a relatively new product that has gained popularity in recent years. They are often used as an alternative to traditional cigarettes, and many people believe they are safer than regular cigarettes because they do not contain tobacco. However, there is still some debate among scientists about whether or not they are truly safer. Some studies have shown that e-cigarettes may be less harmful than traditional cigarettes, while others suggest that they may be just as dangerous. Ultimately, it's up to each individual to decide if e-cigarettes are right for them.
