A modified cigarette is used as a low-cost, widely available combustion engine to deliver high-dose nitric oxide (NO) directly into the lungs of people ill from a viral lung pandemic, similar to the influenza virus or the coronavirus.

A material with combustion retarding properties including a combustion retarding salt and an aerosol-generating material, consumables including the material, and non-combustible aerosol provision systems including such consumables. Methods for manufacturing the material with combustion retarding properties and the use of a combustion retarding salt to retard combustion.

Immobilized diluents in a smoking article are provided, wherein diluents can be immobilized through absorption and/or adsorption of the diluents into immobilizing materials, such as sorbents like silica gels. By immobilizing diluents, the diluents can be available for vaporization, while still being protected from migration and/or loss of the diluents in a smoking article.

The disclosure provides a product including a plurality of beads configured for oral use, the plurality of beads containing bleached plant material, a filler, a binder, water, and at least one flavoring agent, active ingredient, or a combination thereof. Further provided are pouched products including the plurality of beads, and a process for preparing the beads.

A heated aerosol-generating article is provided, including an aerosol-forming substrate including tobacco and a metal-based sulphide scavenger compound, an amount of a metal component of the sulphide scavenger compound in the aerosol-forming substrate is at least 0.05 percent by weight, based on a total dry weight of the aerosol-forming substrate, and the sulphide scavenger compound is based on a transition metal.

The disclosure provides liquid compositions configured for oral use, the liquid composition comprising water in an amount of about 40% by weight or higher, based on total weight of the composition, a flavoring agent or an active ingredient or both a flavoring agent and an active ingredient, and one or more additional components selected from the group consisting of sweeteners, humectants, and alkali metal salts, wherein the composition has a water activity (Aw) of about 0.85 or lower. The liquid compositions are generally suitable for spraying into the oral cavity.

A method of manufacturing a flavor source includes: a step A of adding a basic substance to a tobacco raw material; a step B of heating the tobacco raw material added with the basic substance and releasing an inhaling flavor component into a vapor phase from the tobacco raw material; a step C of collecting the inhaling flavor component released into the vapor phase in the step B; a step D of washing a tobacco residue being the tobacco raw material obtained after the inhaling flavor component is released in the step B, with a washing solvent; a step E of pulverizing or cutting the tobacco residue obtained after being washed in the step D; and a step F of adding the inhaling flavor component collected in the step C to the tobacco residue obtained after pulverized or cut in the step E.

A method for reducing the content of nitrosamines in a tobacco material is provided herein, the method involving the steps of contacting a tobacco material with a treatment solution so as to form a treatment composition containing, in addition to the tobacco material, an acid, a complexing agent, a solvent, and, optionally, a salt, at a pH of about 5.5 or less, to obtain a tobacco material having a tobacco-specific nitrosamine content that is lower than the initial tobacco-specific nitrosamine content. The method can optionally include further processing of the tobacco material. Smoking articles and other tobacco products incorporating such treated tobacco materials are also provided.

The present disclosure provides an aerosol-generating article a sealed container; and a composition contained in the sealed container and comprising a tobacco material and a vaporizing agent, wherein the tobacco material includes an aerosol-generating material and tobacco leaves, and the vaporizing agent generates oxidizing heat when exposed to air such that an aerosol may be generated without a heating device or electric power.

The present disclosure provides various components entrapped within a cross-linked alginate matrix and products including such component-containing, alginate-based matrices. The disclosure also includes a method for entrapping the components, including mixing the component or components with alginate in water, contacting the mixture with a cation to cross-link the alginate, and removing at least a portion of the water therefrom. The resulting component-containing alginate-based material can then be incorporated within various products, e.g., consumable products such as aerosol-generating devices and components, oral products, and conventional smoking articles.
