There is provided a smoking article comprising an aerosol generating substrate and a mouthpiece attached to the aerosol generating substrate. The mouthpiece includes a segment comprising a filtration material comprising polylactic acid, and an additive for reducing phenols. The mouthpiece further comprises one or more wrappers circumscribing the segment, the one or more wrappers have a combined basis weight of at least about 50 grams per square metre (gm-.sup.2).

A smoking article (10) comprising: an aerosol-generating substrate (12) and a mouthpiece (14) secured to a downstream end of the aerosol-generating substrate (12). The mouthpiece (14) comprises a first segment (24) of elastically deformable material, the first segment (24) having a length in the longitudinal direction of the mouthpiece (14) and a width transverse to its length. The first segment (24) comprises an insert unit access portion comprising at least one slit (60) extending along at least a part of the length of the first segment (14), and extending across at least a part of the width of the first segment (14) to facilitate deformation of the access portion, such that an opening (25) is formable or expandable in the access portion of the first segment (14) upon receiving an insert unit (50).

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.
