I'm a little worried about the health risks of e-cigarettes. Is there any research on their safety?

There is some research showing that e-cigarettes may be safer than traditional cigarettes, but more studies are needed to confirm these findings. Additionally, it's important to note that e-cigarettes still contain nicotine and other chemicals that can have negative health effects, so it's best to avoid using them if you're trying to quit smoking.
