The present disclosure provides an aerosol delivery device and a cartridge for an aerosol delivery device. The cartridge can comprise a body defining a reservoir and defining an aerosol pathway in fluid communication with an aerosol outlet. The cartridge can further include one or more of an air entry, a splitter configured to split air entering the air entry into a plurality of air passages, an atomizer, and an aerosol forming chamber where air from the plurality of air passages is configured to mix with vapor formed by the heater to form an aerosol. Preferably, the aerosol forming chamber can be in fluid connection with the aerosol pathway. The present disclosure further can include a control device configured to receive, power, and control aerosol formation by the cartridge.

A cartridge of an electronic vaping device includes a housing extending in a longitudinal direction. The housing includes a sidewall, a transverse wall at the first end of the sidewall, and an inner tube integrally formed with the housing. The sidewall is generally cylindrical and a first end and a second end. The transverse wall includes at least one outlet therein. The inner tube extends in the longitudinal direction. The inner tube is concentrically positioned with respect to the sidewall. The inner tube communicates with the at least one outlet. The cartridge also includes a reservoir between the sidewall and the inner tube. The reservoir is configured to contain a pre-vapor formulation.

A carrier, apparatus and method for making an aerosol precursor liquid suitable for aerosolized delivery by a device such as an electronic cigarette. A carrier is fluid permeable and comprises a tobacco-derived medium for carrying a functional component, the medium being configured to release the functional component into a fluid to provide an aerosol precursor liquid infused with the functional component. A method for mixing an aerosol precursor liquid for aerosolized delivery of a functional component by an aerosol delivery device comprises bringing the tobacco-derived medium carrying the functional component into contact with fluid and allowing the fluid to saturate the medium to thereby cause the medium to release the functional component into said fluid to form an aerosol precursor liquid infused with the functional component. A receptacle comprising a chamber for the carrier is provided for mixing the aerosol precursor liquid. Example functional components include nicotine and nicotine salts.

An aerosol provision system includes one or more receptacles each forming a respective central space, a base adapted to support the or each receptacle, the or each receptacle being removable from the base and at least a first airflow generator, operable to draw air through at least a first aerosol generator, wherein the base includes one or more outlets through which, in operation, aerosolized payload is directed to flow from the base into the central space of a respective receptacle and the or each receptacle comprises a first opening through which the user can inhale the aerosolized payload.
