Nope. Because the equivalent to "It's soda" would be "It's a personal vaporizer." And that's what I say.
If someone asks, "What's in it?" the equivalent answer wouldn't be "water and sugar" -- and the answer to "Is that smoke?" wouldn't be "It's water based vapor," for me. If they want to know what's in the exhaled vapor, I'd tell them it's water-based vapor with traces of nicotine, vegetable glycol, and propylene glycol. Fewer surprises later, that way.
I like the fog machine explanation.
I realize this is just my take on things. I'm less concerned with vaping in peace today than in being able to continue vaping in the future.
I was vaping on the board walk wall on mission beach SD, Ca. When a lifeguard drove up behind me on the sand and said "Excuse me, but there is no smoking on the beach and boardwalk." I said that I don't smoke. He said, "Yea-right,I just saw you blowing smoke". I told him that it wasn't smoke, that it was just vapor. (this was a couple of years ago) He said "what are you talking about ''''''vapor'''''?" I said "you know water vapor ... like fog, steam, teapots, hospital nebulizers. He kept asking me questions because he had a hard time believing me. But I answered them all, including the ingredients.
Since then at the boardwalk (yes, I am a beach bum) Three cops, three different times, the first mentioned "No smoking" I just showed him it was a vaporizer, not smoke and he just said "OK, carry on." I could tell he didn't know anything about them, and he was still standing there talking to a couple other cops. At that time I always carried a little write-up about e-cigs because no one then knew what they were and I was on a mission to let the word out and convert smokers. So I went back up to him and handed him my flier, and he gave it back to me and said: "It doesn't matter to me. You can inhale what you want, it's your life."
The second cop just asked me if that was a vaporizer, then said OK and left. The last one rode up on a bicycle, after seeing me puff, then looked at my hand and told his partner "oh, it is just a vaporizer"
Now, I do say "LIQUID VAPOR" Instead, just because of uptight vapers like these here. But there is NO DIFFERENCE between saying WATER VAPOR or LIQUID VAPOR. It's the same thing.
Is is not lying, all liquid is water-based or petroleum-based. No water is pure except for distilled. What, when you hand a glass of water to your guest, do you say here is your water with a trace of chlorine with a few minerals mixed in with a little bacteria from the pipes. DO YOU.
