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

A smoking article includes an aerosol-generating substrate comprising a flavor delivery material for thermally releasing a flavorant. The flavor delivery material comprises a polymer matrix and a plurality of domains of a flavor composition dispersed within the polymer matrix. The flavor composition comprises a flavorant mixed with one or more triglycerides including at least 30% by weight of triglyceride having at least one carboxylic acid having a chain length of greater than 12. The flavorant is releasable from the polymer matrix upon heating the flavor delivery material to elevated temperatures.

A cartridge may include a housing, a liquid supply reservoir in the housing and configured to store a pre-vapor formulation, a vaporizer, and a porous plug. The vaporizer may be in liquid communication with the liquid supply reservoir. The vaporizer may be configured to generate a vapor from heating a portion of the pre-vapor formulation. The porous plug may be connected to the housing and separated from the liquid supply reservoir. The porous plug may be permeable to the vapor. The porous plug may enclose a flavoring additive contacting a storage material. The flavoring additive may be configured to at least partially elute from the storage material or at least partially volatilize from the storage material if the vapor flows through the porous plug. An e-vaping device may include the cartridge.

A composition that includes vitamin A (e.g., retinol) and vitamin E (e.g., gamma-tocopherol), suitable for at least one of pulmonary administration, aerosolization, and intranasal administration. The composition can further include a pharmaceutically acceptable solid or liquid carrier. The composition can be in a unit dosage form or a metered dosage form and can be configured for pulmonary or intranasal administration. Also included are nutritional supplements, intranasal sprays, pulmonary sprays, pulmonary powders, cigarettes, and/or electronic cigarettes, each including the composition. Also included are methods of administering the composition to a human, e.g., within the oral cavity or within the respiratory system.

A smokeless tobacco product or medicinal nicotine product includes nicotine and camphor dissolved in a non-flavored oily carrier. Preferably, the camphor is present in a concentration ranging from about 600 ppm to about 1300 ppm. Also disclosed are methods of making such products.

A nicotine oral delivery composition includes a source of nicotine and a proflavour compound, wherein the proflavour compound includes a flavour component and a support component joined by an enzymatically cleavable bond, wherein the nicotine oral delivery compound is in solid form, and wherein the enzymatically cleavable bond is not a glycosidic bond.
