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 paper covering covers the metallic foil, the paper covering defining openings via which the electrodes are configured to make electrical contact with the metallic foil. Other applications are also described.

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. The metallic foil is shaped such that at least a portion of the metallic foil is embedded within the smoking material. Other applications are also described.

Apparatus and methods are provided for use with a smoking device that includes an infrared temperature sensor. A capsule includes a smoking material containing one or more active agents. A metallic foil is disposed around at least a portion of the smoking material, the metallic foil being configured to vaporize one or more of the active agents from within the smoking material, by the metallic foil being heated by the smoking device via resistive heating. A coating is disposed around at least a portion of the metallic foil at which the infrared temperature sensor is configured to detect a temperature of the capsule, and/or the portion of the metallic foil is treated, such that the portion of the metallic foil has an emissivity value of at least 0.5. Other applications are also described.

Apparatus and methods are provided for use with a smoking device. An elongate capsule includes a smoking material containing one or more active agents disposed along a portion of a length of the capsule. Two cylindrical elements are disposed at respective ends of the portion of the length of the capsule that contains the smoking material, such that a predefined quantity of smoking material is disposed between the two cylindrical elements. One or more heating elements disposed within the capsule are configured to vaporize one or more of the active agents from within the smoking material, by the one or more heating elements being heated by the smoking device. The predefined quantity of smoking material disposed between the two cylindrical elements is configured to provide a metered dose of the one or more active agents to a user. Other applications are also described.

Apparatus and methods are provided for use with a smoking device. A capsule includes a smoking material that contains one or more active agents. One or more heating elements within the capsule are configured to vaporize one or more of the active agents from within the smoking material, by the one or more heating elements being heated by the smoking device. A collapse-prevention element, disposed along an axis of a portion of the capsule that contains the smoking material, is configured to prevent the portion of the capsule that contains the smoking material from collapsing when mechanical pressure is applied to the portion of the capsule that contains the smoking material. Other applications are also described.
