The point I am trying to make is that no matter how big or small the numbers are, it is getting released in the air and we have to be mindful of it as we don't know the full extent of the side effects. However, we do know how nicotine affects us physiologically and neurologically. We know that children and pregnant people are even more susceptible. I was making that point because I see a lot of ecig users blowing it off as if there is definitively no side effects from the vapor to them or others around.
I know that this gentleman is not in this thread anymore and he's a Reo user (good thing!!!), but I want to make a comment. I'm glad he brings this up. I think more than the "effects" of the nicotine, although it is very miniscule and probably not really doing any harm at all, the notion that the vapor is visible and that some of the vapor has an odor is the issue- I know that people have complained of some of my concoctions that I vape. It doesn't harm them- it just annoys them- very similar to someone who walks by who is wearing and especially annoying perfume (also known as fragrance). If I farted in a public place, this would annoy others too....but if I kept quiet, they might not know the source. I'm just happy that if/when I fart, there is no large yellow cloud emitted that can easily lead the offended to the source. So it is w/ vapor- not quite as rancid, but others still may take offense.
On a similar note- I think in consideration for all the small children and pregnant women- if we spot them on the street, we should immediately take a turn at the block before we get to them and "drive around the block" so that they don't ingest the fumes from our automobiles- and we should also encourage others to do the same. If we continue to drive past them and force them to breath in our carcinogenic auto-fume-vapors, surely to goodness, the FDA or some other Gov. organization should begin a crusade to ban all fossil burners. Certainly there might be some who are already addicted to the carbon-emitting vehicles. Big Pharma should then develop a patch, gum and lozenges to help with this! I'm thinking I will opt for the patch as I've already experienced what a tailpipe of a car tastes like and it wasn't pleasant (don't ask).
So in conclusion- I have only 2 words
VAPE ON!!
Oh, and Postscript- A new flavor juice coming your way- "highway vapor!" for those trying to get off of the carbon, auto-emissions.
