Abstract
A smoking article is provided, including a plurality of elements including a front-plug and an aerosol-forming substrate. A hole or slit is defined through the front-plug, through which a heating element may be inserted. In use, a heating element is inserted into the smoking article through the hole or slit and the aerosol-forming substrate is heated to generate an aerosol. When the heating element is subsequently withdrawn from the smoking article, the front-plug acts to retain the aerosol-forming substrate within the smoking article.
