A simulated cigarette having a generally cylindrical cigarette like housing 1 with a main axis, the housing containing a reservoir 4 of a pressurised inhalable composition. The reservoir 4 has a reservoir outlet at one end which is selectively closed by an outlet valve 5. The simulated cigarette further comprises a tube 20 with a through bore 21 extending along a substantial portion of the reservoir 4 from the vicinity of the reservoir outlet such that composition flows into a tube bore inlet and along the tube bore to the reservoir outlet. The tube inlet end is retained such that the axis passes through the inlet end and so that the tube bore inlet is positioned in the axial sense in the central 50% of the volume of the reservoir. By positioning the tube bore inlet in this way, it is in a position where it is in the vicinity of the centroid of the reservoir such that, whatever the orientation of the cigarette, approximately 50% of the available liquid can be dispensed thereby providing a uniform dosage each time the cigarette is refilled.
