Abstract: Disclosed is a smoking substitute apparatus comprising a first passage for receipt of an aerosol flow, a second passage arranged in parallel with the first passage and comprising an additive delivery portion for delivering an additive to an airflow in the second passage, a mouthpiece comprising an outlet in fluid communication with the first and second passages, and a valve for controlling aerosol flow through the first passage. The valve is movable between a first position in which an airflow drawn through the outlet is received substantially exclusively from the first passage, and a second position in which an airflow drawn through the outlet is received from a combination of the first and second passages.

Abstract: A smoking substitute system (101) having a fluid inlet (107), a fluid outlet (108), and an aerosol generator arranged between the inlet (107) and the outlet (108) and in fluid communication with each. The aerosol generator is operable to generate an aerosol from an aerosol precursor (104). The smoking substitute system (101) further comprises a heater (130) arranged between the inlet (107) and the aerosol generator, the heater being configured to heat fluid drawn through the inlet (107) towards the aerosol generator. A source of flavourant (132) is provided between the heater (130) and the aerosol generator so as to be presented to a flow of fluid from said heater (130) towards said aerosol generator, the flavourant comprising one or more substances that activate at least one of an olfactory receptor in a human nasal cavity and a taste receptor in a human oral cavity.

Abstract: A smoking substitute apparatus has a flavourant-containing element formed by printing a flavourant onto an outer surface of the smoking substitute apparatus. Alternatively a smoking substitute apparatus has a flavourant-containing element on an outer surface thereof, the flavourant-containing element comprising a scented and/or flavoured ink.

Abstract: Disclosed is a smoking substitute device comprising a body, a heating element projecting from an end of the body, a cap for engagement with the end of the body, the cap defining a cavity for receipt of the heating element when engaged with the body, and a lock configured to selectively prevent disengagement of the cap from the body based on a condition of the heating element.

Abstract: A vapour delivery apparatus is configured to deliver a vapour comprising an active ingredient to a user drawing air through the apparatus for inhalation. The apparatus comprises an air passage defined between an air inlet and an outlet, and a vapour generator arranged in the air passage. The vapour generator comprises a substrate loaded with a source of an active ingredient for generation of the vapour. The vapour generator also comprises a constricted air flow region adapted to provide a higher air flow velocity in the constricted air flow region than an air flow velocity in the air passage upstream of the vapour generator for a given air flow rate from the air inlet to the outlet. The constricted air flow region is bounded on at least one side by the substrate to extract vapour from the substrate into the air flow in the constricted air flow region. There is also provided a method of using a vapour delivery apparatus.

Abstract: A consumable for a smoking substitute device contains a liquid aerosol-forming substrate, wherein a solid additive is located within the tank of the consumable. The solid additive 750 is used to add materials to the liquid aerosol-forming substrate.

Abstract: A vaporisable liquid for a smoking substitute apparatus, the vaporisable liquid comprising vegetable glycerine, propylene glycol, and water; wherein the vaporisable liquid comprises less than 5 wt % water and the ratio by mass of propylene glycol to vegetable glycerine is at least 30:70. The vaporisable liquid finds use as an e-liquid in a smoking substitute device.

Abstract: Provided herein is a flavourant provider for a smoking substitute device wherein polysaccharide fibres are cross linked by a flavourant microcapsule and/or nano capsule. Also provided is use of the flavourant provider and a method of forming the flavourant provider.

Abstract: The present disclosure relates to an aerosol delivery component (e.g., a smoking substitute component) comprising: a first aerosolisation portion (which may be a passive aerosolisation portion) configured to generate a first aerosol from a first aerosol precursor; and a second aerosolisation portion (which may be an active aerosolisation portion) configured to generate a second aerosol from a second aerosol precursor. The component further comprises a mouthpiece nozzle rotatable between a first position and a second position, wherein in the first position the component is configured to supply the first aerosol and the second aerosol through the mouthpiece nozzle, and in the second position the component is configured to supply only the second aerosol through the mouthpiece nozzle.

Abstract: An aerosol delivery system comprising a first air passage having a first aerosol generator, and a second air passage separate from the first air passage having a second aerosol generator, wherein the first aerosol generator is operable to generate a first aerosol including an active ingredient, and the second aerosol generator is operable to generate a second aerosol including an active ingredient, the first aerosol being less visible than the second aerosol in use; and wherein the aerosol delivery system is configurable to selectively operate the first aerosol generator alone; the second aerosol generator alone; or the first and second aerosol generators together.

Abstract: A smoking substitute apparatus comprising an air passage, a reservoir formed from an air-permeable substrate and arranged to allow air to be drawn through the reservoir, the reservoir being loaded with a source of nicotine, and one or more one-way valves arranged along the air passage and configured to allow air to flow along the air passage in an upstream to downstream direction.
