Abstract: A device and method for delivering a therapeutic drug to a patient in the form of an aerosol includes a heat generating chamber and an aerosol forming chamber separated by a heat conductor. A heating element is disposed within the heat generating chamber in heat conducting relation with the heat conductor. A substrate having a therapeutic drug and an aerosol forming agent deposited thereon is disposed within the aerosol forming chamber in heat conducting relation with the heat conductor. The heating element ignites a fuel source consisting essentially of a combustible liquefied gas to generate heat that is conducted to the heat conductor and then to the substrate via the heat conductor. The heat generated by the heating element activates the aerosol forming agent to volatilize the therapeutic drug into an aerosol drug contained within the aerosol forming chamber and made available to be inhaled by the patient.
