A system and method for incorporating and releasing a substance into a smokable material is provided. In one embodiment of the present invention, a smokable element (e.g., a cigarette) includes a first wrapper and a filler (e.g., tobacco, cannabis, etc.) encased by the first wrapper. A capsule is then embedded within the filler and a second wrapper is placed over the first wrapper adjacent the capsule. The capsule may comprise a liquid (e.g., cannabinoids, terpenes, etc.) encased within a shell. By squeezing the second wrapper, the shell can be crushed (or broken open), releasing the liquid into the filler, thereby creating a splash zone. Vapors and/or smoke from the splash zone can then be inhaled by a user, enhancing the user's smoking experience.

In another implementation, the mouthpiece may include the flavor addition component, the filter may define a cavity therein, the flavor addition component may comprise a plurality of flavor beads, and the plurality of flavor beads may be located in the cavity.

A smoking article tube includes an elongated tube having a mouthpiece segment at a first end and an empty smokable material cavity defined by a second end of the elongated tube opposing the first end. A hydrophobic tube region includes hydrophobic groups covalently bonded to the elongated tube.

The present invention relates to a multicomponent aerosol-forming article defining a longitudinal axis, the article comprising: a first rod-shaped component comprising a first longitudinal surface having a first and a second axially opposed ends, said first longitudinal surface being at least partially wrapped around the longitudinal axis in a first wrapping sheet; a second rod-shaped component comprising a second longitudinal surface having a first and a second axially opposed ends, said second longitudinal surface being at least partially wrapped around the longitudinal axis in a second wrapping sheet, the first end of the second component being in direct abutment to the second end of the first component along said longitudinal axis; wherein a portion of said second longitudinal surface at said first end of said second component is free of said second wrapping sheet; andwherein said first wrapping sheet is wrapped for at least an overlapping length along the longitudinal axis on the second wrapping sheet.

An aerosol-generating article is provided, including: a rod of aerosol-generating substrate having a length from 8 to 16 mm, the substrate including a shredded tobacco material having an average density from 150 to 500 mg/cm.sup.3 and being in a form of cut filler or a shredded sheet of homogenised tobacco material; a downstream section downstream of the rod and including at least one hollow tubular element abutting a downstream end of the rod; an upstream element provided upstream of the rod and abutting an upstream end of the rod, an upstream end of the upstream element defining an upstream end of the article; and a ventilation zone at a location along the hollow tubular element and being configured to admit ambient air into a lumen of the hollow tubular element, a distance between the ventilation zone and the upstream end of the upstream element being from 26 to 33 mm.

Smoking articles are disclosed herein. The present disclosure is directed to a smoking article that comprises a heat source configured to generate heat upon ignition thereof, a substrate material having opposed first and second ends, the heat source being disposed proximate the first end of the substrate material and the substrate material having an aerosol precursor composition associated therewith, a mouthpiece, the mouthpiece being disposed proximate the second end of the substrate material, and a heat transfer component. In one implementation, the heat transfer component comprises a hollow structure and opposing first and second flanges located on respective ends thereof, wherein the hollow structure extends through the heat source such that the heat source is located between the first and second opposing flanges. In another implementation, the heat transfer component is located within the heat source, penetrates at least a portion of the substrate material, and includes a cap located between the heat source and the substrate material.

A smoking article (10) comprises a tobacco rod (12) and a mouthpiece (14) secured to a downstream end of the tobacco rod (12), the mouthpiece comprising: a tubular element (20) defining a longitudinal channel, wherein the tubular element (20) is provided adjacent the downstream end of the tobacco rod (12); a downstream segment of filter material (24), wherein the downstream segment of filter material (24) is downstream of the tubular element (20) and spaced apart from the tubular element (20) to define a cavity (26) between the tubular element (20) and the downstream segment of filter material (24); and an extinguisher element (22). The extinguisher element (22) comprises: a compressible reservoir (28) provided in the cavity (26) and containing a liquid; a neck portion (30) extending upstream from the reservoir (28) and having an open end, wherein the neck portion (30) is received in the longitudinal channel of the tubular element (20) such that the open end is proximate the downstream end of the tobacco rod (12); and sealing means (32) provided over the open end of the neck portion (30).
