A smoking article (10) incorporates a liquid release component (20), the liquid release component comprising an inner core of a sustained release liquid delivery material and a frangible outer shell encapsulating the inner core. The liquid delivery material comprises a closed matrix structure comprising a cross-linked polymer matrix defining a plurality of domains; and a liquid composition that is trapped within the domains and is releasable from the closed matrix structure upon compression of the material. The frangible outer coating comprises at least one film-forming polymer and at least one plasticiser.

An aerosol-generating article is provided, including: a substrate portion containing aerosol-forming substrate, substrate portion having a length of between 20 millimeters and 60 millimeters and a diameter of between 4 millimeters and 7 millimeters, the aerosol-forming substrate including an aerosol former, and an amount of aerosol former ranging between 6 percent and 20 percent by weight on a dry weight basis of the aerosol-forming substrate; a hollow acetate tube; and an additional filter section included between the substrate portion and the hollow acetate portion.

The invention relates to substrates comprising a support at least partially coated with an aerosol-generating material formed by drying a precursor material whilst in contact with the support, the precursor material comprising an extract from a flavour- and/or active-containing plant material and optionally an aerosol-former material. The substrates may be used to generate an aerosol. For example, the substrates may be used in combustible or non-combustible aerosol-provision systems. The invention also relates to aerosol-provision systems comprising the substrates, and methods of providing a substrate.

The disclosure provides products configured for oral use, the products including one or more active ingredients and a beet material, at least a portion of the one or more active ingredients being bound to the beet material. In some embodiments, oral products as described herein may include a beet material, a filler material, and one or more active ingredients, at least a portion of the one or more active ingredients being bound to the beet material and the filler material. Active ingredients included in the product may be configured for release according to different release rates, which rates may depend at least in part on the material to which the active ingredient is bound.

A substrate is provided comprising an aerosol-generating material, the aerosol-generating material comprising a thermoreversible amorphous solid, the thermoreversible amorphous solid comprising: 0.5-20 wt % of iota- and/or kappa-carrageenan; 20-80 wt % of an aerosol-former material; 20-70 wt % of a flavorant and/or an active substance; wherein these weights are calculated on a dry weight basis. Consumables and non-combustible aerosol provision systems comprising the substrate, as well as methods of making and using these, are also provided.

The disclosure provides products configured for oral use, the products including compositions comprising a filler component including negatively charged groups and an active ingredient including positively charged groups. The active ingredient can be retained by the filler component at least in part through bonding between the negatively charged groups and the positively charged groups such that active ingredient may be release from the product when positioned within an oral cavity of a consumer.
