I don't see what the FDA can really do because the science is totally on the side of vaping from all I've read. You simply cannot make a rational argument that vaping itself is a danger. Because there are no chemicals in water vapor that are remotely dangerous. WHat the FDA may do & what my hunch is that they will do something with regards to e-liquids themselves, all the health goons seem to go back to that point, about "not knowing what's in ejuice", so I predict they will do something to require markings and indgredients on all ejuice, something like that, maybe banning "fruity" or "kid-friendly" flavors. Not sure, but I just don't think they will do much with regards to the act of vaping itself because again there is simply no evidence at ALL that vaping bothers anyone who doesn't vape, unlike with smoking regular cigarettes. So they'll probably issue a bunch of regulations regarding the juice, just to give the health nazis something. Who knows. I am optimistic that the longer it takes, the better the outcome may be.
