A smokeless article for oral delivery of a nicotinic component. The smokeless article comprises a first compartment and a second compartment, which enclose a first content and second content, respectively. The first and second content are prevented from passing between compartments by a barrier. The pH of the first content is different to the pH of the second content, and one of the contents comprise a nicotinic component. A method of manufacturing a smokeless article

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 is flexible and therefore deforms due to the contact between itself and the wick ensuring good contact therebetween. The fluid-transfer article and the heater are separable, to allow the fluid-transfer article to be replaced.

A smokeless article for oral delivery of a nicotinic component. The smokeless article comprises a water-permeable pouch having two or more compartments including a first compartment and a second compartment each containing a content, each compartment, or each content, comprising at least one of a nicotinic component and a flavouring. The format of the content contained in the first compartment is different to the format contained in the second component. Also disclosed is a method of manufacturing a smokeless article, a kit comprising a plurality of smokeless articles, and a use of a smokeless article.

There is provided a handshake process, performed by an aerosol generating apparatus, the handshake process including: sending first information to the external device; receiving from the external device second information in response to the first information; determining whether the second information is valid or invalid by determining whether the second information is derived from the first information using shared knowledge that is shared by the aerosol generating apparatus and the external device; if the second information is determined to be valid, allowing communication with the external device to continue; if the second information is determined to be invalid, performing at least one action to disrupt communication with the external device.

A heat not burn device is described. The heat not burn device is configured to control the operation of the heat not burn device based on a measurement of ambient temperature

A smoking substitute apparatus (105) comprises: a housing having a longitudinal axis; an air inlet (176) and an air outlet (174) formed at the housing; a vaporisation chamber (180) having a vaporisation chamber inlet (172) and a heater (164). The air inlet and the air outlet are in fluid communication with each other through an air flow channel extending between the air inlet and the air outlet. The air flow channel passes through the vaporisation chamber inlet and the vaporisation chamber. The heater extends across the air flow channel. The vaporisation chamber inlet is configured to receive air flow from a substantially radial direction and to change a direction of air flow to an axial direction into the vaporisation chamber. The vaporisation chamber inlet is configured to reduce a rate of change of air flow direction from the substantially radial direction to the axial direction. The housing comprises a radially-extending wall (501) and the vaporisation chamber inlet comprises an axial aperture (620) through the wall. At least part of a perimeter of an upstream edge of the axial aperture is filleted to provide the reduced rate of change of air flow direction.
