To my mind, the fight should not be about whether or not we can vape indoors. It ought to be about whether we can vape at all. As for our vapor being harmless, perhaps the PG/VG component could be shown as harmless but the truth of the matter is that most of us are vaping some level of nicotine. Nicotine is in our exhaled vapor in some quantity. People have a right to not be exposed to the nicotine. That is what it will come down to if we push this indoor vaping thing. It will give vapers a bad image and, as we all know, when it comes to public opinion it all boils down to perception. We are (in essence) contending for the right to force others to be exposed to our vapor whether they like it or not. I have no problem taking my 510 outside especially if that means that John/Jane Doe won't have a problem with e-cigs. I know that some foods contain minute traces of nicotine but they will just argue that they have the right to choose when, how, where, and "if" they are exposed to nicotine. People are scared of the "N" word. Let's not piss them off some more. There is a vape friendly bar right down the street from me but I always check with the people seated around me before I hit the button on my 510. It's just polite and I believe that THEY have as much a right not to breathe nicotine as I have to breathe it. When it comes to indoor vaping, let's err to the margin of caution and consider the rights of others first. I believe that that kind of thinking is what will further our cause with regards to avoiding totall banning of e-cigs. Just my 2 cents.
