Abstract: An inhaler having a housing containing a low temperature material. Positioned in the housing is a coil or other pathway isolated from the housing and defining an airflow passageway. The coil and the air inside the coil are cooled by the low temperature material when activated. The low temperature material is normally in an inactive state, and requires activation in order to cool. Activation can be initiated immediately prior to use by flexing a flexible or collapsible member in which an activating agent is stored. Also disclosed is a method of activating a low temperature material by causing the low temperature material to contact an activating agent, and inhaling (or forcing manually or automatically) cool air from the device to cause cool air to enter the airways of a patient.
