An inhaling device for use for inhaling an active powdered or liquid substance comprises a cylindrical container (10) having a piston (12) arranged therein so as to be movable between upper and lower positions. The piston may be retained in its upper position by means of a releasable locking member (18) and is biassed towards its lower position by means of a spring (16). When the locking member (18) is released and the piston is moved to its lower posi- tion by the spring an active powdered or liquid substance is sucked into the container (10) in dispersed condition from a conventional inhaler (223 communicating with the container. A patient (29), who may be a child or an adult having a reduced lung capacity may thereafter inhale air and active substance dispersed therein from the container (10) through a mouthpiece unit (23) provided with one- way valves (26, 27). An auxiliary chamber may be inserted between the mouthpiece unit (23) and the container (10). The patient, who may be a child, may then inhale air and the active substance dis- persed therein from such auxiliary chamber, only. The volume of the auxiliary chamber may be adapted to the age of a child whereby a dosing possibility is obtained.
