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).
