A condensation aerosol generating device for generating a condensation aerosol of a liquid formulation e.g. nicotine, the device comprising a passageway 108 comprising a heater element 110, an inlet, and an outlet, wherein the heater element 110 is located in the passageway 108 between the inlet and the outlet, and a reservoir 104 comprising the liquid formulation 102, wherein the reservoir 104 is in fluid communication with the heater element 110, wherein the heater element 110 is capable of vaporizing the liquid formulation 102 when the liquid formulation 102 is delivered to the heater element 110, wherein the vaporized liquid formulation is condensed into aerosol particles in the passageway 108, wherein the condensed aerosol particles have a mass median acrodynamic diameter (MMAD) of from about 1 µm to about 5µm. The device may comprise a baffle (4402, Fig 44c) located in the passageway between the outlet and the greater element, wherein the baffle inhibits flow of particles having an MMAD of greater than 5µm. The device may comprise a programmable controller which regulates the dosage, frequency of administration, or delivery schedule. |
