A mouthpiece portion of an electronic cigarette includes a cartridge comprising a liquid store having a housing configured to store a liquid to be vaporized, the cartridge comprising a main vapor channel extending therethrough, between an air inlet opening through a vaporization chamber and to a vapor outlet opening; a mouthpiece connectable to a main body of the electronic cigarette, the mouthpiece comprising a vapor channel for receiving vapor from the main vapor channel of the cartridge. The cartridge is axially displaceable by a consumer with respect to the mouthpiece in the axial direction and movable between a first position and a second position. In the first position both the air inlet opening and the vapor outlet opening of the cartridge are open, and in the second position both the air inlet opening and the vapor outlet opening of the cartridge are closed.

A portable loose-leaf material vaporizer 1 comprises a heating chamber 20 for housing loose leaf material and vaporizing one or more active agents from the loose-leaf material, a mouthpiece 3 for withdrawal of the one or more active agents vaporized from the loose-leaf material, and a processing unit. The processing unit is configured to control temperature of the heating chamber 20 and to estimate a dosage of the one or more active agents withdrawn from the vaporizer 1 based on a mathematical model. The mathematical model relates vapor generating time and loose-leaf material properties, and optionally temperature of the heating chamber 20, to the dosage of the one or more active agents withdrawn or to be withdrawn from the vaporizer 1.
