I concur with the hypothesis that CO was acting as a carrier, and the receptors were more readily able to receive it. Again, though, _I'm_ seeing serum and urine levels consistent with the claims that it's probably bioavailable, more or less. (n=1, not blind, etc, etc)
There's another possibility that doesn't invalidate the work, but does invalidate the study. I don't see where the liquid tested came from. It's entirely possible, either by accident or design, that a supplier shipped 0mg/ml in a 16mg/ml cartridge or liquid, right? It's not like there's an absence of disreputable suppliers, and it's not like there's any lack of manufacturer screw-ups, as we've [nearly all] observed, even from the best of companies exercising best-practices and then some, right?
Regardless: It's a single short-term short-count study. As soon as their underlying numbers are published, anyone can step up and challenge them simply by attempting to repeat their study and subsequent results. The beauty of scientific method!

Actually, it's an LED for teeth whitening--I really saw that ad on TV!
I actually have a larger concern with this....
But the units may deliver hazardous chemicals, according to preliminary checks by federal regulators. In a notice to importers, the FDA blocked continued shipments after finding diethylene glycol, a chemical used in antifreeze that is toxic to humans.
The government's statement noted there are no health warnings on the products, and that "the FDA analyses detected carcinogens, including nitrosamines."
The notice of the import ban says "the product appears to be a combination drug-device," that "requires pre-approval, registration and listing with the FDA" in order to be marketed in the United States.
Wow really? So the FDA gets to do and say whatever they want without producing a valid verified report but since it's on CNN it must be true?
And...all eCigs brands? Really? Really? (Sarcastic really)
This is nutz...leave eCigs alone already Gah...

well, if they state that there is no nicotine then the FDA doesn't have anything to worry about and we can all continue puffing away on something besides analogs. *tada*
There seems to be a mild panic amongst those that want to keep us smoking and paying unfair taxes. They are throwing everything they can at e-cigs hoping to get something to stick. First they said it was a tobacco product, then a medical device and now saying the sellers are making false claims so they should be stopped for that reason. Then the occasional fear mongering buzz phrase...."what about the children."
I have never been a conspiracy theorist. Kennedy was not killed by the Mafia and CIA. The twin towers was not an inside job. And there are no aliens at area 51. But the behavior I am seeing concerning e-cigs makes me believe in at least one conspiracy...the tobacco lobby/government taxes self-sustaining loop. And these folks have the money and reach to get a study to say anything. If e-cigs were subject to the same extortionist taxes as tobacco products....all of a sudden they would be "safe and effective"....I betcha.

I'm not a believer in the conspiracy theories either, but something is deff brewing here. Whenever there is nothing big enough to stop people from buying it they pull the "we need to protect our children card" What about the parents?
In the time it took me to read the article and all the posts here, I dripped about 15 drops on my V2...and I'm blasted.
Perhaps, they should have let them Vape a 5V device !!!

Out of curiosity, did you guys see the comments section (from the CNN story).
I found the comment of "Just google VCU and Philip Morris and you will see that this study should be seriously questioned about its validity" particularly interesting.

Interesting one here also. They do mention the main forum here.

I missed that same link on the first page DOH!

E-Cigarettes Deliver Little or No Nicotine, Study Finds
A small study conducted at Virginia Commonwealth University concluded that e-cigarettes failed to deliver on their promise of providing a dose of vaporized nicotine with every puff, CNN reported Feb. 8.
Sixteen volunteers were given two popular brands of e-cigarettes to use; the tobacco-free devices use a battery to heat a liquid containing nicotine, which users then inhale.
However, "Ten puffs from either of these electronic cigarettes with a 16-mg nicotine cartridge delivered little to no nicotine," according to the study led by researcher Thomas Eissenberg of the university's Institute for Drug and Alcohol Studies, who added: "They are as effective at nicotine delivery as puffing on an unlit cigarette."
The study, funded by the National Cancer Institute, will be published in the British Medical Journal.
Total BS. I can damn well tell a difference between 0mg nic juice and 36!
I couldn't go 30 minutes without a cigarette for 31 yrs, and I switched to vaping and using e-cigs over night, with NO withdrawals
whatsoever! .NONE!!!
I can definitely tell the difference between no nic liquid and liquid mixed with nicotine!
Also, I have MS and Nicotine helps nerve pain, improves cognition, focus and memory, tremor, and such. .I would DEFINITELY notice if I wasn't getting my nicotine, BELIEVE me!.
Infact, I feel 100% better since I switched to e-cigs, than I did using tobacco cigs. .
And besides, have they also tested tobacco cigarettes? How much nicotine do analogs deliver, along with all the other 4000+ toxins????
The fact that thousands of addicted tobacco smokers/chewers have been so easily able to completely stop smoking, in many cases, over night, is nothing short of a miracle and proof enough!!
Their study results are FALSE, and they also needs to test the blood in smokers first, to see how much nicotine is present, I've read that only small amounts will be present in the blood anyhow, so I don't see how they can reach any conclusions without first testing tobacco smoke.
And so what! if the amount of nic turns out to be smaller when using e-cigs, this would only show they are that much better health wise, in that they lack all the other thousands of toxins that tobacco smoke contains, and in that e-cigs are much more efficient in distributing nicotine than analogs, because even with smaller nic amounts, they work or help thousands of people all over the world, and are saving lives and giving many people their health back, and to me, that's all that really matters.
ok, I'll get off my soap box now, lol, it just upsetting to read about studies like this, I mean, if you're gonna do a study, so it right, and do it with 100 people, not 16, and test both tobacco smoke AND vapor, as well as take blood tests, urine tests, and breath tests, or whatever else, lol
