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.

Provided herein is an aerosol-generating article with enhanced vapor production. The aerosol-generating article according to some embodiments of the present disclosure includes a medium portion, a support structure which is disposed downstream of the medium portion and includes a first tubular structure having a first hollow formed therein, a cooling structure which is disposed downstream of the support structure and includes a second tubular structure having a second hollow formed therein, and a mouthpiece portion which is disposed downstream of the cooling structure. Here, an upstream end of the second tubular structure may abut a downstream end of the first tubular structure, and an average cross-sectional area of the second hollow may be larger than an average cross-sectional area of the first hollow. The cross-sectional area difference enhances an air flow diffusion effect, thereby eventually improving vapor production of the aerosol-generating article.

The present invention relates to a vaping article comprising an aerosol-generating zone, a zone for cooling the aerosol comprising a paper in the shape of a hollow tube, this paper comprising a fibrous substrate, and optionally a filtering zone,
characterized in that the zone for cooling the aerosol is functionalized by a plant extract and an aerosol-generating agent.

An embodiment of the present disclosure provides a smoking material wrapper which includes cigar fibers and at least one vanilla material from among vanillin, ethyl vanillin, and ethyl vanillin glucoside, and a smoking article including the same.

A method of manufacturing flavorant particles includes melting a food grade wax and a flavorant into a molten wax; solidifying the molten wax; and grinding the solidified molten wax into a plurality of flavorant particles. Another method of manufacturing flavorant particles includes melting a food grade wax and a flavorant into a molten wax, the molten wax having a melting temperature between about 50° C. to about 70° C.; and spray-chilling the molten wax into at least one solid flavorant particle, the solid flavorant particle having a diameter of between about 0.1 mm to about 2.0 mm.

A smoking article (10) incorporates a tobacco rob (12) and a filter attached to the tobacco rod. The filter includes a concentric filter segment (20) having a central core portion (23) with sorbent material and an outer periphery layer (24) circumscribed about the central core portion. At least about 80 weight % of the sorbent in the smoking article is disposed in the central core portion. The central core portion has a lower RTD than the periphery layer. A ventilation zone (30) is disposed adjacent an upstream end of the concentric sorbent segment.
