| As someone who switched to an e-cigarette, I might be able to answer this for you. The first thing is that the level and effect of nicotine that is absorbed though vapor is a lot less than a regular cigarette. The reason for this is twofold: firstly, the lungs/mouth/throat seem to simply not pick up as much as in a cigarette, and secondly, cigarette smoke also contains MAOIs, which increase the sensitivity of the brain to nicotine's effects. In addition, users can choose the level of nicotine that they use. Most e-cig users who are regular smokers tend to start at around 18mg/ml. When I first started, I was using this liquid in a 1.6ml tank. One tank worked out to about 1 pack of cigarettes worth of nicotine, and I got through about a tank a day: the same amount that I used to smoke in cigarettes, except spread out through a longer period of time. Most vapers will puff way differently to cigarette users. We take one or two puffs at a time and then wait, while a cigarette user will smoke the whole thing quickly in one go. Nicotine has been shown[1] to increase creativity in the brain, and I know from my own experience that I find it to be great while working. Most of my 'House' moments when tackling difficult coding problems have occurred on the curb with a cigarette in my mouth, and now I lean back at my desk and have a few puffs of fine-tasting menthol e-liquid.
