Abstract: An aerosol generating system is provided. The aerosol generating system includes an aerosol generating apparatus and an aerosol forming article. The aerosol forming article includes a solid aerosol precursor, and wherein the aerosol precursor includes a plurality of strips of an aerosol forming substrate. At least one of the strips includes at least one embossed region to increase friction between strips. The aerosol generating apparatus includes a heating system including a heater for penetration into the precursor.

Abstract: A solid aerosol precursor for an aerosol forming article is provided. The solid aerosol precursor comprises a sheet of aerosol forming substrate. The sheet has a longitudinal length and transverse width. The sheet is embossed with a 2-dimensional pattern of embossed regions and the sheet is separated along the longitudinal dimension into a plurality of strips. The strips are gathered together thereby forming the precursor.

Abstract: An elongated smoking article is described that comprises a cylindrical smoking body with a combustible material and a hollow bore filter element downstream to the cylindrical smoking body. The hollow bore filter element comprises a first base area facing the smoking body and a second base area opposite the first base area and a hollow bore extending from the first base area to the second base area. The elongated smoking article further comprises a filter membrane that is arranged between the smoking body and the hollow bore filter, that comprises at least one filter aperture aligned with the hollow bore, that is configured for filtering particles emitted by the heated smoking body, that is permeable for vapor emitted by the heated smoking body and has an effective size between 0.5 ?m and 1.5 mm.
