Apologies if I have put this in the wrong section, I make my own liquids and I have 1 customer who was using it due to health reasons, they recently had a checkup done and the lab results came back saying they found zero nicotine in the blood, now whilst we all agree this is great, the strange thing is this person went from 11mg juice to 6mg juice and uses it a lot, so I am not sure why the results would come back as zero.

Most lab test results have "marker scale" with a max point to be considered as possibly harmful to the body. Even though your customer was using low nicotine the results fell below the marker and was considered "zero" or what labs call undetectable. Also, nicotine is present in the food we consume (potatoes, etc).

I've always wondered about companies now testing for nicotine (smokers) when hiring if vaping with ecigs would cause the tests to be positive even though the applicant is not a "smoker". It would be great to know lab results from a 24mg nicotine vaper.

There was a thread here last year, the guy vaped right before the nicotine byproduct "cotinine" test (he asked his physician to do to actually check the level), & yes he showed up positive.

I cant find the thread easily. I searched again for cotinine, but theres hundreds of threads on cotinine on ECF, & I couldn't get thru them all.

Oh, there it is. I bet that's the one.

Okay, so that guy was vaping quite a bit of 36mg/ml and his nicotine level placed him between the non-tobacco user and active tobacco user. His cotinine level placed him at the very low end of 'active tobacco user'.

6 mg/ml is 1/6 of that level. Do you have any information about what time of day your customer had the blood drawn and how much he had vaped prior to that?
