I think this boils down to the fact that there's more than one definition of smoke. The more restrictive and in my mind more accurate definition, deals with the particles and gases associated with combustion. The more broad definition includes other smoke-like substances such as vapor. If we, as a community, wish to distance ourselves from smokers, it might be in our best interests to utilize the former, more restrictive, definition.
how can that be done when even us vapors can't distinguish the difference visually? no one can say who is and isn't smoking in the pics I put of people smoking because for all intents and purposes they are all smoking... yes one may be vaping, but which one? the general public will never make that distinction
now if we could make the vapor pink, or make the vapor invisible, then maybe we have a chance of really differentiating one from the other, but in reality if you are blowing clouds of what is generally perceived as smoke you don't have a great chance of changing everyone's mind as to what smoking is. ecigs started out wanting to be as close to smoking as possible, and they have achieved that, but now want to be as different as possible. don't get me wrong, I wish I could actually convince everyone that it is not smoke but I don't see that as being possible because what you are emitting is perceived as smoke, so to anyone observing it IS smoke, you are blowing smoke, you are smoking... that will be what anyone would think. arguing against that is futile
I vape, I do not smoke, but I also am not surprised when anyone perceives what I am doing as smoking because as an action I am blowing smoke therefor I am smoking, I can't argue with that logic, yes I can point out the technicalities but in the end anyone who see's my emissions see's smoke. I still say I don't care, call it whatever you want. I can't understand being shocked or disappointed because people see "smoke" and say I'm smoking whether it's technically correct or not. I can't expect people to use a spectrum analysis device to determine what the smoke they see actually is...
