A device for vaporizing and delivering an aerosol agent includes a heat generator, a heat conductor in fluid (airflow) communication with the heat generator, and a substrate holder in heat conducting relation with the heat conductor. The heat generator is a handheld, portable torch and the heat conductor defines an annular heat conducting chamber surrounding a substrate disposed within the substrate holder that supports the aerosol agent and an aerosol forming agent. Another device is a handheld, battery-powered heat generator including a heating element in heat conducting relation with a substrate holder. The heating element is a nichrome heating coil wound about the substrate disposed within the substrate holder and electrically coupled to the battery. Another device further includes an auxiliary heat generator having an auxiliary heating element formed by a finely woven wire mesh positioned adjacent the substrate and electrically coupled to the battery.
