Hmmm..... there may be a product idea someone should offer (hint hint).....
I googled nicotine test strips and only got ones for saliva and urine to see if nicotine is in ones system.
I was thinking it might be a good idea for an enterprising
vaping-supplies vendor to offer test strips one could spread some nobacco
juice on to get a reading. If nothing else as a sort of "our juice is spot-on, and you can even prove it to yourself".
And DIY'ers could benefit. Even those who do a little mixing of pre-made juices could double-check their assumptions based on the ratios they chose for their custom blend.
