A device for controllably dispensing and volatilizing liquid by the user sucking or drawing on the device. An elongate tube defines a reservoir for liquid and air bounded by a solid and a porous plug, and an aperture for the flow of air that is positioned between said porous plug and the open end of the device. A mechanical means of controlling the surface area of said aperture is provided. Three preferred embodiments of said mechanical means include a pleated section with holes in the troughs of pleats, a rotating sleeve about an ovular slit, and a translating tubular insert into the open end of a device with an aperture consisting of a series of holes.
