Very interesting. No wonder the gum fails for so many people. Most smokers crave that "nic fix" that the gum just won't deliver in the way their craving wants it.
It's funny, when I smoked, I would be just fine lighting one up, taking a couple drags, then putting it out. I would be fine with this for a shorter period of time though. This data shows an excellent example of why. Odd though, now that I'm vaping, I don't crave it immediately upon waking, but vape constantly after I start. Also, I can put it down, as opposed to smoking, I would still want one after getting ready to sleep.
Thanks for posting that. I'll have to check out more of your info!
Quite welcome. Constant vaping makes perfect sense when looking at that graph in that the ecigs don't provide the intense spike of an analog, but due to their much slower absorption it takes much longer to build up a level, but once a level is built up, it hangs around longer (flatter profile as opposed to the saw-toothed analog profile) such that one gets accustomed to a flatter profile and is likely spared the acute morning craving.
