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.
