A device for burning smoking material and inhaling the resulting smoke is disclosed. The device can include a tubular member formed from a dried leaf having an internal elongated cavity extending from an open end to a closed end. The elongated cavity can be configured to receive a smoking material. The smoking accessory can include a filter disposed within dried leaf and defining the closed end. The filter can have a recess formed in a surface of the cylindrical body along a curved face extending from the first end to the second end, the recess extending radially into the cylindrical body. The smoking accessory can include a capsule containing a flavoring agent disposed within the recess.

Provided is an adsorbent which does not undergo the seeping of an oily component contained therein to an area surrounding the absorbent and has an excellent property to absorb a specific range of hydrocarbons. More specifically provided is a granular absorbent comprising a granular base material, an oil or fat having a melting point of 50 C. or higher and a polyol.

A process for preparing a filter plug for a smoking article, such as a cigarette, includes: (a) freeze-drying a solution of a biopolymer to form a structure; and (b) cutting the structure to a predetermined dimension, to thereby prepare a filter plug for a smoking article. Another process for preparing a filter plug for a smoking article, such as a cigarette, includes: (a) extruding a mixture of a foaming agent and a biopolymer comprising a protein to form a structure; and (b) cutting the structure to a predetermined dimension, to thereby form a filter plug for a smoking article.
