The inhaler has a catch 49 for moving the indication member from the first state to the second state on removal of the canister 2 from the inhaler. An electrical switch contact 48 detects the state of the indication member 41, thereby providing an indication of whether the canister 2 has been used before. An LCD display is controlled in response to the detection.
