"Pot calling the kettle black" implies a moral judgement. I've certainly never considered either smoking or vaping a moral issue and feel that, for the most part, that's territory held pretty exclusively by ANTZ. What I have, however, versed is a concern for one's health... my own included. Vaping, per se, I don't see as harmful. But.. and that's a big one... done in certain says I do feel it can be... (certainly their is the as yet undiscovered potential.) Its just plain old logic that only breathing "clean" oxygen is the most healthful. I know, I know, where can anyone find that today? I don't know but it stands to reason that deliberately inhaling any substance other than that, when it can be avoided, isn't the healthful way to go. If vaping is done the same way pipe and cigar smokers smoke, then nothing is taken into the lungs. Not so if done the way most cigarette smokers smoke. I was a cigarette smoker but I vape like a pipe smoker. I spent years coughing in the morning from cigarettes and that progressed to trying to clear mucous from my lungs all day as my smoking increased. I also have multiple allergies as well as asthma so its only a natural, with my lungs finally cleared from laying off smokes, that I would now want to protect them all I can so I try not to breath air fresheners, hairspray or anything else I don't have to to protect them. I very much enjoy vaping but only do a throat inhale/exhale when I want to feel throat hit otherwise I just taste the vapor in my mouth and sometimes exhale through my nose for added flavor.. no lung inhaling for me. I think this is the part that is often left out of these discussions and just "vaping" is addressed but not how its done. But, hey, if you want to vape by lung inhalation... its your body and your life and I would say the exact same thing no matter what you want to inhale or not... not a moral issue... no judgements. I get your rant and hope I, at least, have clarified.
Edit: reading this, I know I saw my usual "there/their/they're" typo but can't find it now.

so all you grammar folks.. just ignore it. K?

I seriously hope I haven't wasted my time, energy and/or knowledge on any trolls out for their kicks... hey, got that "their" right.
