Substrates for use with an aerosol delivery device to vaporize and deliver an aerosol to a user include a base material, an aerosol former and an aerosol agent. In a method for forming the substrates, a mixture of substrate materials is extruded and then spheronized to produce pellet substrates that are generally spherical, substantially spherical or rounded, or in the form of relatively short rods having rounded ends. In another method for forming the substrates, a base material is coated with a first coating and optionally the base material having the first coating thereon is subsequently coated with a second coating so as to produce pellet substrates having a relatively smooth, dry exterior surface. In this manner, the substrates are formable relative to one another and can be easily and readily loaded into and removed from the aerosol delivery device.

A combustible heat source for an aerosol-generating article, the combustible heat source comprising: carbon; an alkaline earth metal peroxide ignition aid; and a binding agent comprising at least one non-cellulosic film-forming polymer.

The disclosure provides compositions configured for oral use, the compositions including at least one filler, water, a basic amine, and an organic acid, an alkali metal salt of an organic acid, or a combination thereof, wherein the organic acid has a log P value of from about 1.4 to about 8.0. At least a portion of the basic amine is associated with at least a portion of the organic acid or the alkali metal salt thereof. The association is in the form of a basic amine-organic acid salt, an ion pair between the basic amine and a conjugate base of the organic acid, or a combination of both. Further provided are methods for stabilizing a composition configured for oral use, for enhancing a predicted buccal absorption of a composition configured for oral use, and for reducing potential throat irritation associated with the use of compositions including a basic amine.

A process is disclosed for incorporating additives into aerosol-producing substrates. During the process, an additive is incorporated into an infusing liquid. An aerosol-producing filler is submerged in the infusing liquid and the resulting mixture is subjected to reduced pressures that cause the infusing liquid to infuse into the material. The material is dried leaving behind the additive in a controlled amount and uniformly dispersed throughout the material. In one application, cannabidiol is incorporated into a tobacco filler or a hemp filler.

The invention relates to a nicotine oral delivery product containing a powder enclosed in a water insoluble pouch, wherein said pouch is permeable for saliva and therein dissolved parts of the powder, wherein said powder comprising at least a) nicotine selected from the group consisting of tobacco, nicotine salts, nicotine base, stabilized nicotine, and mixtures thereof corresponding to 0.1 to 20 mg nicotine in the form of nicotine base and b) a chewing gum composition and a method of producing said nicotine oral delivery product.

A technique which, while avoiding excessive conduction of heat to the flavor source, reduces variance of heat conduction, and which makes it possible to reduce the weight and the cost of the flavor inhaler is disclosed. A flavor inhaler which, provided with a cylindrical holding member extending along a prescribed direction from a lighting end to a non-lighting end, includes a combustion-type heat source disposed at the lighting end, a flavor source which, in the prescribed direction, is arranged towards the non-lighting end with respect to the combustion-type heat source, and a cup-shape cup member which holds the flavor source and has a side wall and a bottom plate. The cup member is arranged with the bottom plate thereof disposed towards the non-lighting end with respect to the combustion-type heat source, and is inserted into the holding member oriented so as to open towards the lighting end or oriented so as to open towards the non-lighting end, and at least the side wall and the bottom plate configuring the cup member are configured from a material containing pulp, a binder and a metal soap.

A non-combustible aerosol system includes a heater configured to supply heat to a heating chamber and a housing configured to be inserted into the heating chamber. The housing defines an internal volume for containing a solid substrate. The housing includes a plurality of internal structures extending from a first end of the housing to a second end of the housing, the plurality of internal structures extending through the internal volume, the plurality of internal structures being configured to heat the solid substrate to generate an aerosol by conducting the heat supplied by the heater to the internal volume.
