Apparatus and methods are described for use with a smoking device that includes at least first and second electrodes. A capsule includes a smoking material containing one or more active agents, and a metallic foil surrounding the smoking material and configured to be heated via resistive heating by the electrodes driving a current into the metallic foil. A collapse-prevention element configured to facilitate electrical contact between the electrodes and the metallic foil, by preventing the capsule from collapsing. Other applications are also described.

A filter section for a flavor inhalation article, comprising a paper filter, and an object disposed within the paper filter, wherein the object is harder than the paper filter at a position where the object is not disposed.

Apparatus and methods are provided for use with a smoking device that includes at least first and second electrodes. An elongate capsule has a length of between 15 mm and 150 mm. The elongate capsule includes a smoking material containing one or more active agents, and metallic foil surrounding the smoking material. The metallic foil is configured to be heated via resistive heating by the first electrode driving a current to the second electrode along a length of more than 5 mm in an axial direction along the metallic foil. Other applications are also described.
