The article also delivers very low levels of carbon monoxide. The article is able of providing the user with the sensations and benefits of cigarette smoking without burning tobacco. The article includes a carbonaceous fuel element, an aerosol forming substance within a heat conductive container, an outer member surrounding the heat conductive container, and a mouthend piece. Upon draw on the mouthend piece air enters the peripheral region of the outer member and enters the heat conductive container. As the heat conductive container is in a heat exchange relationship with the fuel element, aerosol is thereby formed within the container and passed to the mouth of the user.Other References
