How much nicotine does vaping really deliver?

[baobei]

I googled this and found an apparent scientific study that said that vaping delivers 'hardly any' nicotine at all into the bloodstream.

I find this hard to believe since I feel quite buzzed after vaping 24 or 26mg juice.

I've started vaping 6mg to try to becomes less hooked on nicotine. Anyone know if vaping really delivers a lot less nicotine than regular smoking?

There are a lot of factors that contribute to how much nic you get from vaping. Your technique has a lot to do with it. The vapor particle size is much larger than smokw, so your lungs don't absorb as much as your mouth and nose will. Also you are not getting all the chemicals from tobacco, that add to nicotines effectiveness. If you feel you are getting too much nic try a lower level. If you've just stopped smoking, it also may be withdrawls from all the chemicals you aren't getting now too!

Recent tests by Etter, measuring cotinine levels (what nicotine metabolizes to), showed levels in experienced vapers comparable to smokers.

Generally, the tests showing no or low nic absorption have used cruddy pv and uneducated users, basically tossed as pv with no instruction on how to vape.

Search ecf for Etter and look at posts in the January/February timeframe.

I'm not really sure to make of any of the "studies," but here's the thing, I really don't care if I'm actually getting nicotine or not. As long as I feel like I'm getting nicotine, and satisfied vaping enough to keep me away from cigarettes, that's good enough for me.

Forkeh, I agree!

i have given myself nicotine induced anxiety with vaping(by vaping way too much)............trust me, we are getting nicotine.

 

[baobei]

nicotine can you give anxiety!?

considering that Im coming off a can a day chew habit and have cut myself to 2-3 chews a day tells me Im getting nicotine. Its not even like Im replacing cigarettes. This is totally different. Ive tried the gum, ive tried the patches. i always wanted to tear someones head off. I dont with the ecig.

at really high doses any stimulant can give you anxiety.

At first, I saw the reports that hardly any was delivered and believed it. Now I know better, though I don't have any scientific proof to offer. I am still very hooked on nicotine. I cut down from 36 to 24 with no problems. Then I tried to cut down to
< 12. The result was that I went through 15 ml in just two days, which is twice what I would normally use. I didn't realize I was vaping so much until I looked at the 30 ml bottle and saw half was gone. The next batch I went with 24 mg and I'm back to my 3 ml per day. I also nearly smoked a cigarette while using the 12 mg. Was about to ask a friend for one, then thought to myself that was odd and stopped myself.

There's an interesting discussion on this subject on the E-cigs in the media and news forum

Actually the patches work great. Put one over each eye and you can't see to find your cigarettes.

I remember something about that study. It was some time back. I believe there was a problem with the methodology and it was later discredited.

Yeah, wasn't that the one that used low quality kit and people with little to no vaping knowledge? The later Etter survey (mentioned earlier) refuted that one

Here's the letter documenting Etter's findings late last year: http://www.stop-tabac.ch/fra/images...p_tabac/e-cig cotinine final erj 20110111.pdf

As a comparison, here's a writeup on measured cotinine levels in smokers: http://aje.oxfordjournals.org/content/151/3/251.full.pdf

The first paper shows ENDS (Etter's term for PV) median cotinine level of 322 ng/ml. In the second writeup you see that that is right in the PAD equivalent level (Figure 1).

I think the main thing here is that we ALL know that we are getting nicotine from our PVs and juice. I know for a fact that, if I vape non stop, I will get an overdose of nic and feel just the same as I would if I smoked too many cigarettes. So, I don't need a study to tell me that PVs work


Instead of spending time to discuss if nicotine is actually delivered to our bloodstream, let's discuss how PG, VG, flavors and/or poly fill affect our body.

Moved to Nicotine from E-Cigarettes in Public

I've calculated about how much nicotine I got when I smoked, smoking all I want, and also calculated how much I get from vaping, all I want, and they are pretty similar. I also have to go without vaping for extended periods at work and have found that the effect from going without vaping and going without smoking is pretty similar.

I read the post on these studies and they referenced different "brands" of e-cigarettes and found there was a wide variety of absorption. So that tells us all we need to know about that. So if you use a good PV and vape at 4 volts or higher and use quality juice rather than who the hell knows what, your results can definitely vary from any of these studies

I'm doing my own DIY juice and at 12mg after a few vapes I get dizzy. Cut down to a formula of around 3mg and it seems to be just nice although I'm not getting much throat hit. I noticed nicotine gives a real good throat hit as well!
