Please read the rest of that article, including the paragraph you quote from, to see why you generally can't get nicotine poisoning from even hardcore smoking.
Also, this doesn't answer GP's question about nicotine causing breathing problems - besides the pedantic observation that your lungs will shut down with the rest of your body when you get lethally poisoned.
Is it bad to jump to conclusions that it's safe and everybody else should be happy inhaling your exhaust believing so?
What someone does in their own homes is fine, though this thread was discussing vaping-exhaust being fine in public, and I don't believe people have that right.
Smoking was predominent in restaurants and public areas a while back and we thought it would be impossible to go away, and now that it has, it's been absolutely fantastic.
This is basically just a "safer", not "safe" method that still affects people in a given area.
I'd rather people just use patches or something else rather than vaping down the street, in malls, or sidewalks. This would be completely fine - mind you - that it is likely to have very negative health consequences to those people.
Why?
Vaping e-cigs in your own home is merely a bunch of orders of magnitude less harmful than doing it in your face.
And according to your reasoning so far, several orders of magnitude less harmful, means you should only be mildly less concerned about that.
Quickly, I hear someone's burning plastic in China.
Are you sure you replied to the right comment? I don't see how any of this relates to what I said. Also, by all means, please show me studies linking nicotine (outside of cigarette smoke) to serious health problems.

Then tell me how much nicotine one would ingest from second-hand vaping in public places. Harm by homeopathy?
