The Missing Nicotine
Posted 09-30-2009 at 09:26 AM by DVap
I ran the vaping experiment with an argon trap, and under the conditions I used, for every 1 mg of nicotine vaped, 0.46 mg of nicotine made it into the vapor... 46%.
I've been arguing for some time that there's a "40% rule" in play for vaping versus smoking. I've observed empirically that a good number of vapers who "find their level" tend to vape 2.5X more nicotine per day than they used to smoke per day. At 46%, the multiplier is 2.17, very close to the 2.5 figure I arrived at by observation.
The equivalence is open to discussion and debate, but the experiment does support the idea that atomizers take a toll on nicotine in e-liquids.
I'm looking at designing a further experiment to find the percentage of inhaled nicotine that is exhaled, this represents the last piece of the puzzle (at least as far as I'm capable of working it out).

Yeah, I'd be interested in seeing how much is exhaled.
I'm sure a lot of people would.

Unfortunately, at the nicotine levels expected in exhaled breath, the exhaled CO2 will impact the determination since CO2 is mildly acidic... enough so to mess things up.
It can be tested accurately, but not by the method I have at my disposal.Posted 11-07-2009 at 06:40 AM by DVap -
If testing a 'vape-free' exhalation (for CO2 baseline) then comparing to exhalation post 60mg/ml vapor, could enough accuracy be achieved to at least define the ballpark?
