I don't know what's written on the pack of typical cigarettes, honestly, I kind of have a feeling that may vary from where you are to what manufacturer. I don't think I've ah, seriously searched for a nicotine level on one, though frankly.
I don't know how much it matters? There isn't a 100% 1 to 1 convergence of nicotine in cigarettes vs. nicotine in vape, vape is absorbed differently, and also reacts differently when it's vaped than when it is combusted.
I am not entirely clear what you are asking either as delivery "amount" per "vape" also varies. It depends on your equipment, the wattage you use, your type of inhale and a ton of different factors. So, I'd be hard pressed to say "Use this much nic."
I can tell you that I used to smoke 3 ppd and vape 18 mg/ml liquid and I don't keep track of how much I vape, but I can also tell you that I vape like I smoke, with abandon.
There are some kind of across the board standards as far as 1 ppd if using MTL say 12--15 mg/ml
juice, or if using DL, say 3--6 mg/ml juice (more vapor per inhale) but really if you are satisfied and aren't
vaping 24-7 you are probably in a good zone.
