Another method of delivering a therapeutic dose of a bioactive agent to the pulmonary system, in a single breath, includes administering from a receptacle enclosing a mass of particles, to a subject's respiratory tract, particles which have a tap density of at least 0.4 g/cmand deliver at least about 10 milligrams of the bioactive agent. The receptacle can have a volume of at least 0.37 cm.
