How much nicotine are we actually getting from vaping

In the Nicotine section there is a huge thread "so, are we getting it or not" that has all kinds of info. I read a formula in there that based on testing, 60% of the nicotine is lost in the vaporization process.
Quick answer is practically all of it, but slower than with ciggies.....
From what I can gather from lab. testing on juice & vapour,
for example LibertyStix latest testing of JC juice:
http://www.libertystix.com/LibertyStixLabAnalysis072309.pdf
The gas-chromatograph of vapour in that report (fig 2) shows a large spike of nicotine
= 3-(1-methyl-2-pyrrolidinyl))-pyridine)
and a much smaller spike of the (probably) primary heat breakdown-product
= 3-(1-methyl-1H-pyrrol-2-yl))-pyridine (or at least something very similar).
So showing most of the nicotine in the vapour is intact.
Also the tests in the thread:
http://www.e-cigarette-forum.com/fo...ow-much-nicotine-destroyed-during-vaping.html
Shows that the total amount of nicotine present in the juice,
is still in the vapour as nicotine & (the smaller amount) of breakdown products .
So the answer is that you get nearly all the nicotine, that is in the juice, into your
mucous-membranes (in your lung / mouth) still as nicotine, but it's all 'wrapped up' in PG or glycerol
That just leaves the question of how much/quickly the nicotine gets from there into your
blood stream (say compared to the high effeiciency smoke in ciggies).
The answer to that appears to be 'most of it, but significantly slower'.
It's almost certainly released quick enough, such that the half-life of nicotine in the body (about 2 hours),
can't remove it before you get most of the effects.
I think of vaping (in terms of nicotine uptake & rate) as 'slow purified cigarettes', or very fast patches.
Also I think/feel that because of the slowness (c.f. ciggies), people tend to take in more nicotine than
they would when smoking, increasing their nicotine 'resistance' (& possibly dependence) in the process.
Then there's the question of what else comes from ciggies that you 'miss',
the thread linked by pianoguy above really shows some good info on that
(e.g. all the other 'minor' alkaloids apart from nicotine)
The 60% nicotine loss (40% recovered) mentioned above by pianoguy is actually a very low figure
that really should be 'at least 90% recovered, nearer 100% when atomizer coil is kept wet/gurgling'.

(not sure if this is the right place for all this, but the question was right)

All I know is that I rarely have had a nic-fit since I started vaping. Either I am getting more when I vape that what I got smoking -OR- I just do not need as much since I am getting all nicotine instead of all the other crap that are in cigarette... or maybe a combination of both.
search results turned up nothing but i know i seen that thread before
The built-in search function of the forum throws out words with less than 4 letters I think, which can provide less-than-stellar results. But...the google search box way down at the bottom of the page works. Just search for "so are we getting it or not" and the proper thread comes up.
Or, just click:

Dang! I never noticed that search box. Its almost like they're trying to hide it!
Thanks.
Thanks.
Yay! After all the take-take-take I do by reading PawPaw's posts, I finally get to give back a little! Woot! 
I think there is something else in tobacco cigs that is addicting other than the nic. I don't have the fits either since I've been doing this for awhile and can go longer and longer without even vaping at all. Used to it was about every 15 min or half hr. I lit up, now I can go 4 hours and not even think about nic at all.
I have done reading on that myself .. and I believe the figure was actually above 92% recovered .. I have also found info stating that nic takes 40 minutes to be fully absorbed as well as run its full course throught the body. Over time, our nicotine concentration grows by percentage because our bodies grow a tolerance to it and therefore the level of nicotine we demand grows right along with that. This is why vapers generally have to start at levels of nicotine that are way higher than what we obtain from cigarettes to begin with and reduce our levels of nic while vaping.
Plus, Ammonia has been added to cigarettes for years to influence a secondary tolerance that our bodies build up and this becomes habitual, as well.

Its true,I dont have to stop what Im doing to vape.It can wait till Im done and I dont have nic fits anymore.

I'm extremely flattered that you feel that way.
I'll warn you right now though, helping is almost as addictive as nicotine!
