Abstract
An inhaler is instantly activated upon its removal from a cover or cover unit, and by rotating a cartridge component of the inhaler with respect to a mouthpiece portion, so as to create a flow pathway for ambient air and particles. The cartridge component includes a chamber, whose contents typically include dry powders or the like. Upon creation of the flow pathway, the contents of the chamber are instantly accessible for immediate inhalation by a user through the mouthpiece portion.
