For years the prevailing belief is that we are getting significantly less nicotine from vaping than from smoking.
Some estimates have ranged as low as 10% and some as high as 40% or even higher.
We have evidence from some studies that novice vapers are getting little to no nicotine.
And we have evidence from other studies that experienced vapers CAN get significant nicotine, in some cases almost as much as smoking.
So we have people going through 5ml per day of 18mg juice, which would be the equivalent of almost 5 packs of smokes.
Some go through even more juice per day, and some use even higher strength than 18mg.
And yet, it is quite possible that even these people are not getting much more nicotine than they did when smoking.
And they certainly were not smoking 5 packs per day.
Then we have the discussions about whether or not we are exhaling nicotine into the environment.
Most research is saying that we do not exhale appreciable amounts, implying that we are absorbing almost all of it.
So are we absorbing all of it or not?
If not, where is the rest going?
I think it is possible that significant amounts of nicotine may not make it into the vapor in the first place.
Perhaps that gunk the builds up on your atomizer includes not only flavoring and coloring compounds, but also nicotine.
Has anybody seen any research on what percentage of nicotine is making it into the vapor?
