Do e-cigs deliver nicotine?

[matt1988]

Sorry I'm not sure if its been covered or their is newer info/tests been done, but I was trawling through another forum, looking primarily at passive vaping, and came across 3 researches and these have shown that the level of nicotine and cotinine are far less than what you would see in a normal analog smoker.

www.e-cig.org/2010/07/28/a-clinical-laboratory-model-for-evaluating-the-acute-effects-of-electronic-%E2%80%9Ccigarettes%E2%80%9D-nicotine-delivery-profile-and-cardiovascular-and-subjective-effects/

I can't find the second tests.

I also found a vapourer that had blood tests done, after chain vaping on the way, showing similar results. These these researches were done last year.

So the question is, do e-cigerretes actually give us a nicotine hit? If so is it any where near as much as smoking?

Ok I have now found this fom ECCA

www.eccauk.org/index.php/consumer-affairs/33-nicotine-equivalency-of-ecigarettes-vs-cigarettes.html

Seems that this is a very unknown subject, more than I first thought when I started last week. Maybe I'm just opening a can of worms for myself and I am now going to close it, so that too many don't escape

The study took people who had never vaped before, were not allowed to smoke for 10 hours, and then told to take 10 puffs. I'm not surprised they didn't get much nicotine.
They reported that the e-cigs reduced their craving, but after 10 hours without fags anything the got to suck on probably felt good.
It seems clear to me that experienced vapers do indeed get nicotine from the ecigs. Anyone who doesn't believe that should try switching to 0mg.
I reckon that new vapers either learn how to take longer drags etc, or come to places like this for help, or go back to the fags.

Ok I have now found this article from thw same professor as the one I couldn't find in my OP, which contadicts his first findings.

So it appears that look-a-likes mixed in with not drawing on it correctly, does mean you get miniscule amount of nicotine in your system.

But when you 'upgrade' to a larger battery and a better delivery system (presumably not a wadsed carto) you can cam just as much nicotine as an analog.

Sorry for posting 3 times in my own thread, but I was just confused and there are so many contradicting arguements.

I listen to my own body in all honesty Matt . . . I know when I need more nicotine and when I've maybe overdone it a bit. Studies like this don't interest me as we're all different in our individual vaping requirements.

But I appreciate that they can have their merit if you're that way inclined, just not for me, I'd rather be doing than reading about it.

Of coarse they do find me a study that shows where the nicotine that does not make it to the vapour is hiding, then I will take the links you posted as educational.

The writer from ECCAUK sounds like he/she is floundering about, out of their depth. Quite frankly it is not helpful to publish an analysis of an investigation unless qualified to do so. I feel the same way as Pertpetua - I thought we all did.

I actually think these are some interesting findings, and just goes to show much more research is needed. I'm no scientist, but it could suggest that the different nicotine delivery system has a different effect on blood levels. I know for myself, not vaping for a few hours is MUCH easier than not smoking for a few hours ever was. Is it because I'm used to lower levels, effectively having weaned myself off higher nic blood levels but quelling cravings with the mechanical motion of smoking? Is it something else? I'd love to find out and will be keeping an open mind on the subject

I think there is also something in the idea that 'technique' plays a part. The technique to vaping is very different to smoking. With a cig you take a quick deep drag, and pull it as far into the lungs as possible then blow out the smoke. With vaping you need to take a long (3-4 second) slow draw. Keep the vapour in your mouth and throat for a couple of seconds (this is where the nic is absorbed) then either inhale it or simply exhale, prefereably through the nose which helps with the flavour. I'm pretty sure any smokers used in a study will use the smoker's technique rather than the vaper's technique and therefore not get as much nic as an experienced vaper does.
I'm with Perps on this one though - find what works for you, not what may or may not work for experimental guinea pigs.

[matt1988]

No I agree. Let your body do the talking, but as I said I just accidently stumbled on them when researching passive vaping. But if the studys are so variable with the actual inhaler, then who knows whats actually in the vapor and how much is then absorbed by the passive smoker.

I think we all do really Perps, we arent consciuosly doing it. It was the same when we were smoking, we didnt do it by the stop watch, our brain`s told us "time to light up". It is the same with vaping. With something like an iclear30 which produces loads of vapour it seems to happen less often with me. It would be great to be able to quantify it. I have an evic which is going a long way to doing that. I am hoping that pretty soon it will be able to tell me how many minutes and seconds I have been vaping in a given period. So if I start vaping a lower nic juice I will be able to see if I am actually vaping more to make up for it. The software has improved on it with the upgrade but there is scope for it to do a lot more.

I think the mechanical motion of smoking/vaping are very important. I still do many of the things I did when smoking to the point of actually going to the back door. It can also be a "time out" which we have got used to over years of smoking.

Very true, I actually miss that time out as I work from home and it used to be a little break, every hour on the hour. I might have to reinstate it

[matt1988]

Yes a break outside to faff on your phone to catch up on crap from fb or twitter haha!

Yes, it was 20 mini breaks throughout the day and was a major reason (for me anyway) for failing to give up the ciggies before, I missed the nicotine obviously but I missed the physical habits maybe just as much. After 40 years of smoking and countless soul destroying attempts to stop, taking up vaping has been relatively painless. Mentally I am at the point where smoking is rediculous when I can satisfy my smoking needs by vaping in more or less the same way as before, except now I dont have to put a leaf filled tube of paper into my mouth and set fire to it
