The Electronic Cigarette (e-cig) is increasingly recognized as a pharmaceutical/medical device because the digital smoke appears helpful in reducing the nicotine addiction and the reduction of damages from tobacco. However, to this aim, it is not enough to know the nicotine concentration in the liquid digitally smoked, because there is no notice about the quantity of liquid digitally smoked, until the liquid tank of the e-cig is empty. This means that there is no notice about the equivalent of one cigarette has been smoked because there is no end-cigarette control in the e-cigs commercially available. Therefore, in this paper, criteria are proposed, implemented and simulated for a fine control of the inhaled nicotine based on a notice of end-cigarette given to the smoker. It is proposed a logical design of the e-cig with the end-cigarette control: the logic model is implemented in a digital circuit model, useful to design the e-cig for a fine control of the inhaled nicotine. The fine control of the nicotine is necessary to reduce the addiction from tobacco and related damages.
