The flavor delivery article further includes a flavor liquid contained with the interior storage volume of the hollow elongate unit. The flavor delivery article may be positioned anywhere within an aerosol delivery device (or a mouthpiece or a cartridge of an aerosol delivery device) wherein the flavor liquid may pass through the substantially continuous wall to be entrained in an air stream and/or vapor stream and/or aerosol stream passing through the aerosol delivery device.
