I agree, but people who vape are (generally) moving from something that has a lot of known risk. Moving from smoking tobacco to vaping is likely orders of magnitude lower risk, just from the fact combustion isn't happening.

I agree that we should get more information about the risk of vaping, but the wholesale banning of vaping is likely to be more harmful than just leaving things as is.[1]

[1]Not saying you are arguing for banning vaping, but FDA did take that position originally until they got smacked down
