Systems, methods and apparatuses for aerosolizing all or substantially all plant matter, medications, flavors, smells, liquid and/or other material to be aerosolizing are disclosed. Embodiments of the invention comprise an aerosolization chamber sealed except for two or more conduits, a first conduit coupled to a source of fully or almost fully oxygenated gas, a heating element capable of heating the aerosolization chamber to a temperature above a combustion temperature, a second conduit configured to transport aerosolized gases and elements out of the chamber and, in one implementation, at least one valve positioned in the second conduit preventing the flow of atmospheric air into the vaporization chamber. In some instances, the first gas substantially clears the vaporization chamber of atmospheric air prior to reaching combustion temperature. A second gas containing oxygen may be intermixed with the vaporization gases and vaporized elements proximal to the combustion chamber.
