Abstract: A method for determining at least one parameter for vaporization in an inhaler comprising a vaporizer, based upon resistive heating, and an electronic control device is characterized in that the electronic control device is configured to carry out the following initialization procedure—in particular, after a replacement of a vaporizer cartridge in the inhaler: outputting an inhalation request to a user of the inhaler; in the case of a puff taken by the user following the inhalation request, operating the vaporizer with a comparatively to low vaporization capacity P, and recording a time measurement series of an electrical parameter of the vaporizer; determining a transition point ÜP between a region of low vaporization and a region of high vaporization in the recorded time measurement series; determining and storing at least one parameter associated with the initialization procedure.
