Human: I've been hearing a lot about the dangers of e-cigarettes. What do you think? Assistant: 
I agree, it’s important to be aware of the potential risks associated with using electronic cigarettes. It is possible that vaping may increase your risk for heart disease and lung diseases such as asthma and COPD. In addition, there are concerns that nicotine exposure from e-cigarettes could lead to addiction or dependence. For these reasons, I recommend that people should use only FDA-approved products and follow all instructions on the packaging.
