Eh, you'd need to show me some evidence that e-cigs are more unhealthy than drinking soda, or the exhaust in a big city. Standing in the sunlight is also harmful; want to ban that?
Comparing e-cigs to other unhealthy things does not make e-cigs any better for you.
Best advice. Don't be stupid. Don't smoke anything at all. It's unnatural. Your lungs are trying to tell you something when you first try it. Listen to them.
