Abstract: A method for adjusting nicotine content of aerosol in an inhaler comprises: a feeding step in which at least one liquid having a first nicotine content is fed from a vaporizer tank to an electric vaporizer; a vaporizing step in which the at least one liquid is vaporized producing an aerosol; and a dispensing step in which a final aerosol consisting of a combination of all aerosols formed in the inhaler from the at least one liquid is dispensed from the inhaler to a user, wherein: at least one of the at least one liquid comprises a precursor substance capable of being converted into nicotine by a chemical reaction; and the method further comprises a nicotine generation step in which said precursor substance is converted into nicotine by the chemical reaction so that the final aerosol comprises a second nicotine content higher than the first nicotine content.

Abstract: An inhaler comprises a housing, an air channel extending between at least one air inlet opening and a suction opening in the housing, a dispensing element for vaporizing or nebulizing liquid supplied to the dispensing element for admixing with air flowing in the air channel, an electronic control device, an electronic data memory, and a sensor system comprising a flow measuring device for measuring the volumetric and/or mass flow of air flowing through the air channel. The electronic control device is adapted to capture a plurality of airflow measurement values over at least a portion of the duration of an inhalation puff by means of the flow measurement device, compare the plurality of airflow measurement values to a puff profile stored in the data memory, and output a control signal based on the comparison of the plurality of airflow measurement values to the stored puff profile.
