1. A device for entraining a substance within an airflow comprising:
- an airway comprising an inlet, and an outlet;
a plurality of supports disposed within the airway;
a substance disposed on at least one of the plurality supports;
a mechanism configured to release the substance from each of the at least one of the plurality of supports; and
airflow routing means for routing an airflow within the airway to entrain the substance in the airflow when released from a support and for inhibiting deposits of the substance on any other support.

2. A device for producing a condensation aerosol in an airflow comprising:
-
an airway comprising an inlet, and an outlet; a plurality of supports disposed within the airway; a substance disposed on at least one support of the plurality of supports; a mechanism configured to vaporize the substance from each support of the plurality of supports on which the substance is disposed; and airflow routing means routing an airflow within the airway to forms condensation aerosol particles from the vaporized substance that is entrained in the airflow when vaporized and for inhibiting deposits of aerosol particles on any other support. - View Dependent Claims (3, 4, 5, 20, 21, 22, 23, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55)

8. 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 of the heating elements; and an actuation mechanism configured to transfer energy from the power source to each of the plurality of heating elements;
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. - View Dependent Claims (9)
