The invention provides an inhalation device for enabling a user to inhale at a desired inspiratory flow rate and/or pressure, comprising a feedback system configured to indicate to a user by means of a signal during an inhalation maneuver whether an inhalation parameter, such as the inspiratory flow rate, is within a predefined target range. The signal may be an optical or a non-optical signal, such as a light signal, an acoustic signal, or a tactile signal.
