Portable vaporizing device and method for inhalation and/or aromatherapy without combustion

A method to produce a condensation aerosol from a solid source material disposed in an hand-held apparatus, comprising the steps of:

• supplying a hand-held apparatus comprising a mouthpiece tube, a source material chamber in communication with said mouthpiece tube, a heating element assembly weighing about 6 grams in communication with said source material chamber, a temperature sensor to monitor the temperature of output air from said heating element, a temperature control module interconnected to said temperature sensor, and an air pump in communication with said heating element assembly;
• disposing a solid source material in said source material chamber;
• energizing said air pump;
• energizing said heating element assembly, wherein said temperature control module regulates the power provided to said heating element, and wherein said temperature control module throttles current flow to said heating element as the temperature of said output air approaches 450 ° F.;
• providing ambient air from said air pump to said heating element assembly;
• providing heated air from said heating element assembly to said source material chamber;
• convectively heating said source material using said heated air;
• vaporizing one or more volatile compounds disposed in said solid source material;
• emitting from said mouthpiece tube a condensation aerosol comprising said one or more volatile compounds.
