FYI.....I was a PAD smoker of 'regualar strength' cigs. When I started vaping, the first few sample flavors I tried were listed as 12mg. I'm not sure why, but 12mg damn near knocked my socks off in some cases and seemed too HIGH. I am experimenting with flavor samples of varying nic levels and am finding that 6 to 10 mg is very satisfying in most cases. I have no idea why this is true in my case.
I am trying to find the most satisfying vape at the lowest nic levels possible, eventually going to zero nic. I could easily see myself continuing to vape at 0 nic if the flavors continue to taste this GOOD! YMMV.
