A smoking article includes a mouthpiece having an outer surface and a cooling agent inclusion complex disposed on the outer surface.

An additive assembly for an e-vaping device includes an adsorbent material that includes adsorbed carbon dioxide. The additive assembly may be in fluid communication with a vaporizer assembly that forms a generated vapor. The adsorbent material may release the carbon dioxide into the generated vapor based on at least a portion of the generated vapor adsorbing on the adsorbent material. The additive assembly may include a flavor material including a flavorant. The adsorbent material may generate heat based on at least a portion of the generated vapor adsorbing on the adsorbent material, and the flavor material may release flavorant into the generated vapor based at least in part on the heat generated by the adsorbent material. One or more of the adsorbent material and the flavor material may be included in beads. Adsorbent material and flavor material may be included in multiple additive structures within the additive assembly.

A method for adjusting nicotine content of aerosol in an inhaler comprises: a feeding step in which at least one liquid having a first nicotine content is fed from a vaporizer tank to an electric vaporizer; a vaporizing step in which the at least one liquid is vaporized producing an aerosol; and a dispensing step in which a final aerosol consisting of a combination of all aerosols formed in the inhaler from the at least one liquid is dispensed from the inhaler to a user, wherein: at least one of the at least one liquid comprises a precursor substance capable of being converted into nicotine by a chemical reaction; and the method further comprises a nicotine generation step in which said precursor substance is converted into nicotine by the chemical reaction so that the final aerosol comprises a second nicotine content higher than the first nicotine content.

Disclosed is a copolymer that includes a repeat unit containing a flavorant-containing pendant and a salt-containing repeating unit. In addition, a comestible, a smoking composition, a smoking article, a smokeless tobacco composition and a heatable or combustible product are provided which incorporate one or more of the flavorant-containing copolymer.

Disclosed is a smoking article containing a rod containing a smokable composition, an optional wrapper for the rod, and at least one polymer or oligomer comprising monomer units of a polycarboxylic acid ester disposed on or in the rod, the wrapper, or both. The polycarboxylic acid ester contains an acid moiety having at least two carboxylic groups, and at least two alcohol moieties independently selected from those corresponding to a cycloalkyl alcohol or an aryl alcohol. The cycloalkyl alcohol or aryl alcohol is a flavorant, or chemesthetic agent, or both. In addition, a method for the controlled release of these flavorant or chemesthetic agents is described, which comprises pyrolyzing at least one polymer or oligomer.
