A tobacco smoke filter or filter element comprising: a longitudinally extending core which includes first and second longitudinally extending rods of tobacco smoke filtering material, wherein the first rod of tobacco smoke filtering material is distanced longitudinally from the second rod of tobacco smoke filtering material; a wrapper engaged around the first and second longitudinally extending rods such that the wrapper defines a cavity between the first and second rods of tobacco smoke filtering material; and at least one receptacle for an additive located in the cavity, wherein the maximum width or diameter of the receptacle for an additive is less than half the maximum diameter of the cavity and the void space remaining in the cavity is greater than 50% of the volume of the cavity, the receptacle being free to move within the cavity.

A method of manufacturing a wrapper for an aerosol generating article includes applying an adhesive to one surface of a metal layer and attaching a first paper layer thereto, applying the adhesive to the other surface of the metal layer and attaching thereto a second paper layer different from the first paper layer, and drying the adhesive applied between the metal layer and the first paper layer and the adhesive applied between the metal layer and the second paper layer.

There is disclosed a mouth piece, filter element or cooling element 100 comprising: a longitudinally extending core of filtering material 102; one or more channels 104 extending longitudinally from an end of the core 102; wherein the or each channel 104 has a non-circular transverse cross section which varies in the longitudinal direction by rotating about a longitudinal axis I of the mouth piece, filter element or cooling element 100.

Heat-not-burn articles are provided. In some embodiments, the heat-not-burn article may comprise: an inner core comprising at least one compressed rod of cannabis-based material; and an outer sheath comprising a sheet of plant-based material, the outer sheath receiving the inner core therein. The heat-not-burn articles may be heated without combustion to generate an inhalable aerosol and/or vapor, thereby reducing or eliminating undesirable byproducts typically associated with smoke. Also provided are related methods and systems for making a heat-not-burn article.

A cigarette mouthpiece is described. Embodiments of the cigarette mouthpiece include cigarette mouthpiece made from a strip of flexible material having a varying width. A width of the strip of flexible material can help determine a length of a user engagement portion and a cigarette engagement portion of the cigarette mouthpiece. The cigarette mouthpiece can have a substantially circular cross-sectional shape and a diameter of the cigarette mouthpiece can be adjustable. Typically, an outside diameter of the cigarette engagement portion can be altered to fit into differently sized rolled cigarettes.

Exemplary embodiments of the present disclosure are directed to a smoking article having a burn portion and a mouth portion. The burn portion includes a smoking rod filled with a smokeable filler material formed almost exclusively of cellulose material. The mouth portion includes either a filter portion with or without an interface or a tip with an interface. The mouth end may include an orthonasal property and the interface may store an additive.
