What I'd like to see is a real measurement of actual nicotine in airborne suspension for a cigarette compared to an e-cig. I get the feeling that's what this ban is seeking to demonize, but that's the proof that is actually lacking as well. Not knowing just yet what particular angle they're going to argue, I don't want to leave the "even airborne nicotine is bad" argument dangling.
Someone get me that, I'll send you some Dogecoin! (j/k, but I might)
Edit: Found something interesting - Safety of cotinine in humans: physiologic, subjective, and cognitive effects.
Safety of cotinine in humans: physio... [Pharmacol Biochem Behav. 1997] - PubMed - NCBI
"This study demonstrates that short-term administration of cotinine to humans at levels as high as 10 times that attained from cigarette smoking is safe with no observable acute or withdrawal effects from cotinine in this setting."
Given that recent studies shows that SHS (second-hand-smoke) has approx 1/10th the nicotine of a directly inhaled cigarette, and that e-cigs emit approx 1/10 the amount of airborne nicotine as a cigarette, I'd say there's zero cause for alarm. Like 1/100 the the cause for alarm of tested safe levels of nicotine exposure.
And that number falls in line with the number of VOC's found in vape as well.
