  • Publication number: 20190116866
    Abstract: Tobacco smoking mixtures capable of producing tobacco smoke are provided which reduce the cytotoxicity and/or mutagenicity of the tobacco smoke. The tobacco smoking mixtures include tobacco cut filler and glycerin in an amount effective to reduce cytotoxicity and/or mutagenicity of smoke produced by the tobacco smoking mixture. The tobacco smoking mixtures enable a further reduction in cytotoxicity and/or mutagenicity when glycerin is combined with palladium or salts of calcium and/or magnesium.

  • Publication number: 20170251722
    Abstract: A flavor assembly for an e-vaping device cartridge encloses a porous structure that enables elution of flavorants from the structure to form a flavored vapor. The structure may include a three-dimensional network of material. The flavorant may be infused in the material. The material may include a botanical material. The material may draw the flavorant from a reservoir. The flavor assembly may direct a raw vapor formed by a vaporizer assembly to pass through the porous structure, so that the flavorant is eluted from the structure into the vapor to form the flavored vapor. The flavor assembly may be removably coupled with a vaporizer assembly. The flavor assembly may be removably received into a flavor assembly compartment. The flavor assembly compartment may be removably coupled to a vaporizer assembly. Flavor assemblies may be swapped from the e-vaping device to enable swapping of flavors provided to adult vapors during vaping.

  • Publication number: 20170251723
    Abstract: 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.
