Yes.
Not sure why the difference in "feel". Maybe it's the lack of carbon monoxide. I use "extra high" 24mg liquid, and each puff should have half the nicotine of a comparable puff from a real cig. I never get any nic hit, however. That's one reason why I use everything else I can
throw at my addiction: real pipes, snus, hard snuff. E-smoking lacks taste, vapor volume and nic hit for me.
Note that the FDA -- I'm convinced it will become involved at some point -- limits nicotine to 4mg for all nicotine-replacement therapies (NRT). That's one reason patches, gum, lozenges, inhalers, all fail. The smoker is left in constant, relentless craving. Not enough nicotine.
Same with e-smoking for me. I puff for a half hour .. and it only makes me want a real cigarette.
I was fascinated by Ruyan's answer to a comment I made elsewhere in this forum about the new KissBox. It said they are "limited by government" or something like that. Huh? What government? What limitation? I read that to mean we will NOT get a nic hit now or in the future.
