The operating mode being selectable by the user via user input means. The heater is for engagement with a heated tobacco consumable, the heated tobacco consumable including an active component for delivery to the user. The at least two user-selectable operating modes include: a first mode in which the heater is operated to deliver a first amount of active component to the user, and a second mode in which the heater is operated to deliver a second amount of active component to the user. The second amount of active component is higher than the first amount of active component.

Abstract: A smoking substitute system and device including a heater. The heater includes a heating element (223A) including a resistive heating track formed thereon. The heater further includes a tapered tip (223B) for penetrating a consumable engaged with the device. The heating element is formed from a heater material of a first thermal conductivity and the tapered tip is formed from a tip material of a second thermal conductivity. The second thermal conductivity is lower than the first thermal conductivity.

Abstract: An aerosol delivery system has a fluid transfer article with a first region for holding an aerosol precursor, and a wick which extends from the reservoir and makes abutting unbonded contact with a heating region of a heater of the aerosol-delivery system. There may be a seal closing the reservoir, with the wick extending through the seal so that aerosol precursor may pass from the reservoir through the wick to the heating surface. When the heater is active, that aerosol precursor will be heated to form an aerosol or vapour. When the user sucks or inhales through the aerosol delivery system, air flows through the air-flow pathway across the heating surface of the heater, so that aerosol passes from the heater and/or wick to the user in the air-flow. The heating region of the heater may be flexible. It may therefore deform due to the contact between itself and the wick ensuring good contact therebetween.

Abstract: A fluid transfer article has a first region having an aerosol precursor and for transferring said aerosol precursor to an activation surface of a second region of said article, said activation surface being disposed at an end of said article configured for thermal interaction with a heater of an aerosol-generation apparatus, and the aerosol precursor having a first dynamic viscosity in an unheated state and a lower second dynamic viscosity in a heated state, wherein in the unheated state the aerosol precursor is substantially retained in the fluid transfer article, both at atmospheric pressure and when a pressure below atmospheric pressure is applied; and in the heated state the aerosol precursor is substantially drawn from the activation surface of said article when a pressure below atmospheric pressure is applied. Advantageously, this combination of features provides a fluid transfer article that does not substantially leak excess aerosol precursor when heated by a heating element.

Abstract: A smoking substitute device is described along with a smoking substitute system comprising the device. The device includes a controller configured to determine the remaining usable lifetime of a consumable in a smoking session, and display said remaining usable lifetime in predetermined intervals at a display. Methods of determining the amount of remaining consumable for a session and displaying the result to the user are also described.
