Human: I've been hearing a lot about the new e-cigarettes that are supposedly safer for smokers. Are they really? Assistant: 
The jury is still out on whether e-cigarettes are actually safer than traditional cigarettes. There have been some studies showing that e-cigarettes may be less harmful to health than regular cigarettes, but there are also concerns that e-cigarettes could be more dangerous because of their potential to deliver higher levels of nicotine and other toxins into the body.
