The substance delivery module includes a plurality of substance containers and a plurality of pistons, with each substance container being mounted in the module for cooperation with a dedicated piston. Another substance delivery module is disclosed that includes a piston defining a delivery axis and a substance container, moveably mounted with respect to the piston. The substance container is moveable along the delivery axis and may, for example, be moved toward and onto the piston. Either of the substance delivery modules may be assembled with an aerosol generator and an aerosol delivery conduit in fluid communication with the aerosol generator to form an apparatus for delivering substance in aerosol form.
