Patent ID: 8333197

Claim:
A device for delivering a condensation aerosol comprising a substance to a subject comprising: a dispensing unit comprising: a first housing comprising a receptacle for a separable cartridge; a controller for controlling vaporization of the substance; and a power source; and a separable cartridge comprising: a second housing; an airway contained within the housing having an inlet, and an outlet; a mouthpiece coupled to the outlet; a plurality of electrically resistive heating elements disposed within the airway; the substance disposed on at least one electrically resistive heating element of the plurality of electrically resistive heating elements; and an actuation mechanism configured to transfer energy from the power source to each of the electrically resistive heating elements of the plurality of electrically resistive heating elements, which have a substance disposed thereon; wherein an airflow from the inlet to the outlet of the airway causes the substance to vaporize and condense in the airflow to form a condensation aerosol.
