For commercial reasons the concentrations of nicotine in blood were redacted for the public domain. The purpose of the information available is to clearly show that there are pharmacokinetic similarities between traditional smoking and electronic cigarette smoking.
One point that must be made, and has been made previous by Mr. Newns, is that these results are specific to the Intellicig. Changing the vaporiser, programme, battery, liquid (strength, ingredients, viscosity) will all alter the absorbance.
I can confirm in terms of safety (Cmax and AUC) are both below that of the traditional cigarette and more similar to that of traditional NRTs. Tmax does however differ greatly from gum, patches, lozenges and inhalators.
