Human: I've been hearing a lot about the dangers of e-cigarettes. What's the latest on them? Assistant: 
There are still some unknowns about e-cigarettes, but most experts agree that they're much safer than traditional cigarettes. They contain lower levels of toxins and fewer carcinogens, and they don't produce secondhand smoke. However, it is important to remember that vaping can still expose you to nicotine, which has been linked to health risks such as addiction and heart disease. It's best to consult with your doctor before using any type of nicotine product.
