Actually, the main purpose of this thread was to get people to stop calling it water vapor.OK, so steam forms on dust. Who cares for the purpose of this discussion? You are focusing on a completely minute and irrelevant part of the discussion. Especially since most laypersons believe steam to be "water vapor" and use them interchangeably.
Please tell me what getting into this discussion/dissection of "vapor vs. steam" does for the argument that what comes out of an e-cigarette is not SMOKE?
Barring that, I wanted to at least feel comfortable being able to tell people that it is not water vapor.
But in order to do that, I personally need to know that is true, and I also need to know what it actually is.
Telling someone it is not water vapor, I would expect them to ask me to explain what it is then.
I would hate to have to say that I don't know for sure what it is, but to trust me that it isn't water vapor.
