Let's see if I can reply to all these in one post...
Equipment: Wifey bought a Kanger EVOD and it seems to work great (but what would I know at this point?). After having it for only 24 hours, she is already a firm convert... which leaves five unsmoked cartons of her cigarettes (Golden Harvest Light, filtered cigars = 100mm cigarettes but 1/4 the price) still
on the shelf. I tried her new toy for a few hits (? tokes? sucks? not entirely up with the new lingo yet). She got several 15ml bottles of flavored juice (Mt.Baker stuff), all at 50/50 PG/VG at 18mg nicotine. Supposedly, that would be a medium level - IF you inhaled the same way as if you were smoking a cigarette (or so I've been led to believe). I have ordered a 618 e-pipe (Ebay, cheap, so it will ship directly from China)

and it isn't likely to get here for a couple more weeks. Other than an occasional suck on her e-cig to understand what she is talking about, I will stick to my cigarettes until my e-pipe arrives. (I chose the pipe version because the batteries are huge, as is the cartomizer, so it will go longer between refills/recharging)
Somewhere on this forum, she read that inhaling cigarettes transfer the nicotine into the blood stream mostly through the lungs (fairly common knowledge), but that e-cigs, whether or not you inhale, transfer the nicotine mostly via the mucus membranes in the mouth and nose, so you will get your "hit" whether you inhale to the lungs or not. I do not know if that is true, but it seems to work that way because I have discovered, by playing with her new toy, that I apparently have never completely inhaled 48 years worth of cigarettes (1-1.5 packs per day). A full-flavor cigarette should have at least that much nicotine and I have never had a buzz like this vapor thing gave me. As I said in the opening post, I smoke cigarettes the same way as cigars and pipes: suck it in, taste it, smell it, but almost none of it goes in my lungs. If that is truly the case for me, then a full-flavored cigarette (what is that? 24mg? 32mg equivalent?), which does
not transfer its full hit of nicotine through the nose, and if almost none actually makes it to the lungs, is probably vapor equivalent to... what? ... 6mg? 3mg? or almost none? This might also imply that my "smoking habit" is really no more than an oral fixation... a need to suck on something (yeah, I was weaned from the teat way too young).

One might even get away with saying that I never really
smoked but have been vaping cigarettes all these years.
Does that imply I should go with minimal nicotine, 25/75 PG/VG, and heavy on the flavor (chocolate, strawberry cheesecake, etc.) to curb the impulse to snack?
Thanks for your support,
