• an electronic delivery system 40 shown in Figure 1 comprises a vapor generating device 10 in accordance with the invention.
• Vapor generating device 10 is enclosed in a housing 46.
• a disposable cartridge 42 with a mouthpiece 44 is attached to and partly inserted into housing 46.
• Vapor generating device 10 is completely enclosed within housing 46 and is shown schematically only.
• At least one air inlet 17 is provided and extends into an interior space within housing 46.
• the invention relates to a vapor generating device 10 for generating a vapor from a liquid, wherein said liquid comprises nicotine or a salt thereof.
• the liquid is contained in a reservoir 14 supported inside said disposable cartridge 42.
• a vapor generating device 10 shown in Figure 2 and Figure 3 comprise a base plate 11 and an elongated wick or similar liquid carrying element extending from base plate 11 inside a tube 30.
• Tube 30 is hollow with an interior void formed as a central bore 26 in which a wick 24 is received.
• An electric heater 20 encloses a heater section 22 of the wick 24 and the tube 30. Electric heater 20 and housing 46 cooperate to form a vaporization chamber 18 schematically shown in Figure 2.

• the system is calibrated to give a predetermined dose of the active ingredient, such as nicotine or a salt thereof every time the power source is activated.
• said predetermined period of time starts when a pressure transducer senses a change of pressure caused by inhalation in mouthpiece by a user. Said pressure transducer can be arranged in the vicinity of air inlet 17.
• the liquid in the cartridge may be a liquid such as those disclosed in the PCT application WO 2015/177177, comprising Propylene glycol, water and nicotine or a salt thereof.
