I liken it to the potpourri metal rings that fit over the light bulbs. You pour a couple of drops of scented oil, and the heat vaporizes the oil. Ignition or flammability may not be the best description of ejuice characteristics. If I were a lawyer, I would have a field day with the definitions - regardless of which side I chose.
From a recognition standpoint, I guess I'm sitting on the fence. I certainly don't want it banned, and would like to see it promoted as a smoking alternative. Those that oppose it, whether it be individuals, businesses, or the workplace are going to continue to oppose it. The opposition will stand strong, whether the topic is smoking, religion, political party, etc. But, is it our mission to go out and proclaim "THIS IS NOT SMOKING, and I'm going to do it wherever and whenever!" ? Is discretion warranted? Is it a problem to be discreet?
Sometimes they say the squeaky wheel gets the grease, but a lot of folks I know hate that damn squeaky wheel.
