Abstract: A method of making a prepackaged, combustible unit of a plant based material for use in an inhalation system, metered dose inhaler, or dry powder inhaler. The method includes creating and shaping a combustible material packaging by processing leaves or plant fibers into a fibrous sheet, steaming the fibrous sheet, and using a female mold and a corresponding male mold to shape the combustible material packaging. The method further discloses filling pockets disposed within the combustible material packaging with the combustible material and sealing the combustible material packaging around the combustible material to create a prepackaged, combustible unit. Additional embodiments include various inhalation devices, inhalation systems, kits having instruction as to using the inhalation device, and methods of making the prepackaged combustible unit, and methods for using the inhalation devices.
