An inhalation device is provided by means of which material in powder form can be inhaled. A stack of powder containers (2) is held in the device and is urged towards one end by a spring (12) or other resilient member. A use station is located at or adjacent that end, where powder can be inhaled from a container (2a) at the use station. Used containers (2) are fed to a storage area, for example a second stack which may be interconnected at its lower end, via the resilient member, with the lower end of the first stack.
