Abstract
To disperse inhaling powders, a powder is positioned in a passage of a device for dispersing powders, wherein the passage has one or more exits, one or more inlets and one or more obstructions to block the movement or to contain the powder within the device before use. A breaching pressure differential between the one or more exits and the one or more inlets of the passage is applied to breach the one or more obstructions, which fully or partially aerosolizes the powder, thus releasing a fully or partially aerosolized powder from the device.
