Thought about this, but actually sat and done it tonight:
Compare your nicotine intake from vaping to what it was from your analogs.
I was smoking an average 25 a day L&B gold. That's 22.5mg of nicotine a day.
I vape 3-4ml of juice a day at 28mg: 112mg....
I did drop to 18mg, but found it lacked the throat hit and went back to 28mg.
Have I REALLY quadrupled the dose with vaping? Is that because I'm substituting all the other stuff in analogs for more nicotine?
In any case, what I'm NOT getting is 250mg of tar and 250mg of CO2, cyanide, etc.....and feel good, so to he'll with the sums

[Neozero]

Sorry CO, not CO2 (though no doubt was inhaling that too)

[steffijade]

I suppose it would depend on the absorption rate, but I was smoking at least 30 a day of menhols that were labeled as 0.8mg.

I vape about 5 mls of 5mg liquid on an 'average' day, but if I'm in chain vaping mode that can probably double.

edit: enetred incorrect figure for nic content.

Inclined to say as a 'deep inhaler' I seem to absorb pretty well and pretty fast. If I've not got my PV to hand and reached the craving stage, it takes just 2-3 good inhales to ease the craving.....The rest, I think, is me just enjoying a good Vape!. That said, even if my intake is higher, I seldom suffer side effects.

[steffijade]

About the only time I seem to suffer from side effects is if I vape Green Cow all day... I can get a bit of a headache but that might be down to the added caffiene/guarana.

[Neozero]

Yeh, I'm a stickler for green cow too. One of my all-day vapes. I'm also a caffeine junkie though, so no effects with that either
Nicotine, caffeine....It's what props us NHS staff up, especially on a Friday night 12hr shift

I love the taste, but could do without the added caffeine. I'm a bit of an insomniac and I don't think it helps me with sleep.. but we've all got our crosses to bear. Some more than others.. such as hard pressed NHS staff.. got nothing but admiration for you and your colleagues. I think you do a good job despite being overworked, often underpaid and all too often, under appreciated.

Good on you.

[Neozero]

Red bullion is a close, caffeine-free alternative.

I really don't think you can compare nic intake from fags against ejuice Neozero as no one really knows a comparison of nic absorption in ejuice.

At the end of the day your body will tell you when you have had enough and what you are comfortable with.

Trial and error I'm afraid as what suits me will not probably suit you.

At the end of the day whatever you settle for will be better than fags we hope.

some recent research i did says a fag actually contains say 15 mg of nicotine it varies quite a bit.. .. the figures you are using is what you absorb..

use the figures right and you get a different picture..

i did write this up not so long ago but like everything useful on this place it just gets lost..

check up on the dry weight of nicotine in tobacco.. weigh a fag and then redo your figures.. or look back for what i idid..

[Neozero]

Will check it out Trog. I honestly can't believe I AM actually hitting my body with 4x nicotine. Would be like smoking a 100 a day....I'd be puking my lungs up!!

[steffijade]

I've done a little bit of snooping on this and from what I can gather, the average nicotine intake per cigarette is around 1mg. This varies from brand to brand and also seemingly, varies with lower and higher tar cigarettes. Seems like there is a loss of part of the nicotine per cigarette due to sidestream smoke and retention in filter tips.

Realistically though, I suppose it would depend on how many drags were taken off the cigarette, how deep and long the inhalations were etc.

There is though, virtually no sidestream loss with e-cigs.

The absorption rate could be affected by the density of the actual particle size of vapour vs smoke too I suppose?

Seems like there's quite a lot of research into nicotine levels for cigarettes, but not so much for e-cig vapour. We'll only probably find out the true facts when truly independent studies are commissioned by groups that don't have a vested interest one way or the other (the anti smoking lobby & e-cig/e-liquid manufacturers).

[Trog]

the biggest mistake is folks use the 1 mg absorbed factor from fags and compare it with the total mg content of e liquid..

this produces duff figures and false conclusions.. my research suggests a fag has 15 mg of nicotine in it.. this turns the figures totally around..

there is no "scientific" figures as regards absorption figures for e liquid.. but if one assume folks balance out their e liquid use with their previous fag use a rough idea can be arrived at..

if a fag contains 15 mg of nicotine.. dry weight calculations say it does.. 20 fags equals 300 mg.. 3 mil of 24 mg liquid equals 72 mg...

this suggest the absorption factor from e liquid is better than from tobacco..

not all e smokers do the balance trick.. some for various reasons waste the stuff.. they produce vapour for fun not the need for nicotine..

Put like that, I feel quite holy and healthy now

[nudger1964]

when there was this last debate i did actually trawl through some threads in ECF.
The most interesting stuff i found was the threads where people were actually giving themselves cotinine tests, or gettting labs to do it for them. The results where very mixed even for people on fairly simular vaping habits.
Buy yourself a test kit and do it yourself...we need more data on this stuff.
