While their influence is obvious the outcome is still fine by me. Many insurance policies do not distinguish between smoking and vaping. Let alone the fact that anything you ingest or inhale that is sold should be proven safe. Where is the proof that they are safe than supports your statement its against the public health to do this?
Considering the amount of money cigarette manufacturers pay out to the government and states it makes sense that anything that takes their place needs to be proven safe or not safe and then handled accordingly.
