Systems, methods and apparatuses for vaporizing all or substantially all plant matter, liquid and/or other material to be vaporized are disclosed. Embodiments of the invention comprise a vaporization chamber sealed except for at least two conduits, heating element, a first conduit coupled to a source of fully or almost fully non-oxygenated gas, a heating element capable of heating the vaporization chamber to a temperature above a combustion temperature, a second conduit configured to transport vaporization gases and vaporized elements out of the vaporization chamber and 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.

The invention provides an inhalation device system for the inhalative administration of a medically active liquid in nebulized form, the system comprising an inhalation device and an exchangeable reservoir for holding the medically active liquid, wherein the inhalation device comprisesa housing having a receiving unit, the receiving unit having a connection unit adapted to releasably and fluidically connect to a connection port of the exchangeable reservoir, the receiving unit being adapted to receive and fluidically connect to the exchangeable reservoir; a nozzle for nebulization of the medically active liquid; and a pumping unit arranged within the housing and adapted to be fluidically connected to the reservoir (via the connection unit of the receiving unit) and to the nozzle and being adapted to convey (pressurize, pump) the medically active liquid in a downstream direction from the reservoir to the nozzle.
