Perhaps is this an old issue but I have not run across it in the context of the e-liquids that most of us use. On another thread the issue arose concerning a rain storm that brought several people in close proximity and a vapers choice to vape. The issue was the negative looks that accompanied the vape. Suspecting that those negative looks arose from the vapor (or mist or fog or whatever it is) that came with the exhale, it seemed reasonable that a stealth type e-liquid should exist for occasions that might require a vape but without the vapor. And, it seems reasonable that this is doable. That is, instead of PG or VG as a carrier of the nic, why can't the nic work with some other carrier that is not "smoke" intensive. For example, why not nic and water? Why not nic and ethanol? Is there not an e-liquid that provides the nic but with the "smoke"? Not suggesting this for an everyday vape but perhaps on "special" occasions. Any thoughts on the matter?
