Home Test for Nicotine Blood Levels ???

[Phayah]

Really odd about the different results...

I guess more extensive testing would have to be done.

Something does seem amiss. Those results don't jibe with everything else we have learned about nicotine from vaping. Need more tests, at longer intervals.

[rejoice]

Now I am confused. One got low results and the other high results.
Seens we do not have the answer. I do not know which is right.

That's a huge discrepancy between the tests from my juice use and Joanna1010. I would want to hear more, guess we will have to wait until she's back from vacation, somethings seems very off, by at least 500ng/ml between the two, even with her small samples with PV/analog combination. She is going to do 2-3 more tests, later on, perhaps will see a difference. Her testing also differs from the Ruyan testing.

I do however feel ok with my testing results, and you can see the photos in post #78 they are difficult to see, so wondering if she had the same trouble. Need to talk further.

I have just ordered another test kit, will re-check for verification purposes.

I have actually found a home test.....................jitters= too little,...headrush=too much

I have more in stock for $5.95 a piece or 4 for $20

OMG that was FUNNY !!!!!!!!!!!!!!

Okay, now I understand. I wasn't sure if you had explained where the info came from and I missed it or what. This should be interesting because even though I got my first e-cig basically just to keep from fighting with ashes and such while I'm working on the computer, I ended up smoking this all the time by accident (basically the very first day). I wasn't necessarily planning to quit smoking. My first thought would have been that I'm getting far more nicotine than before, but at this point I really don't think that's true. Now if someone could just figure out why it was so easy to switch...

YES! For me that is THE question....

Truth be told I always Enjoy a Kreel post. Don't always agree.... don't think so.

OK, a week of 24mg and still tests at 66. Will try dropping it some more for a couple of weeks and retest.

Thanks for the update, JoAnna! Another very interesting result. Just when I thought that one has to vape intensively xx-high to max-out the test... So, this was achieved with medium-high liquid vaping? Could you add some estimate on your mileage? May not have been the same amount of cotinine (the proxy for delivered nicotine) from vaping and analogs, since highest test level is anything above the cutoff (> 1000 ng/ml). But certainly appears to be effective vaping.

Seems there can be much variation for different individuals. Just compare some graph, randomly picked from a scientific study, showing smoking habit and cotinine in urine concentrations [ng/ml] of 128 test subjects. Graph for illustration, not meant to be authoritative, here. While there is a dose dependence for the average, not everyone is the average, as reflected by the large error bars. Damn, I really thought this would turn out to be simple!

I’m by no means an expert in biology or medicine. I just find the question of actual nicotine delivery from vaping personally interesting and highly important. And while we keep speculating, I‘d certainly prefer to read some professional expert’s informed opinion... But looking from my laymen’s perspective, I think that all results from the home tests (as gratefully posted by Minimike, Kate51, JoAnna1010) are (1.) internally consistent and (2.) do support the prevailing notion from user experiences and the first reports of the Laugesen/Ruyan-team, suggesting that vaping is significantly less effective for nicotine delivery than analog smoking.

It has to be noted that the Nymox home test appears to come with a relatively low cutoff (equivalent to 1000 ng/ml cotinine in urine, according to the simplistic product flyers). Most moderate smokers of 10-19 cigarettes per day would score the highest level, score above the 1000 ng/ml cutoff (see the illustrating graph above). Moreover, reading from this illustrating graph, even some occasional to light smokers would score above this cutoff. Just don’t bash JoAnna for her personal body functions, individually different for every one .
Nevertheless, a value of 200-500 ng/ml reported from someone (Kate51) who - by all means - reported constantly vaping 24 mg strength (and so I’d guess runs > 2 ml/day) IS a bench. There is not much chance that a one-pack-a-day smoker would return such a low cotinine level. But certainly, more testing and professional, better informed opinions are needed.

This seems to verify what other studies have concluded: A user of medium strength nicotine would take in what a smoker of 10 cigarettes a day would ingest. Personally, that's not enough for me, a former 30-a-day smoker. I have to resort to snus, dissolvables, nasal snuff and a pipe.

My body certainly told me that long ago. I cannot get enough nicotine from e-liquid vapor. But we are all different, and some might be completely satisfied with e-smoking.

This DOES prove that any e-smoker will flunk a company test to separate smoking and non-smoking employees for hiring or insurance purposes. Those "smoking" tests are really nicotine tests, and e-smoking is just another way to fail them.

When asked "are you a smoker?" the test answer is "yes", no matter your protestations.

actually, most questions are, "are you a tobacco user?" On insurance and health forms.
Also, if you lie for insurance purposes and die or get sick and it is related to your use of tobacco the insurance company will do anything in its power to not pay your claim.
