## Abstract

There is described an aerosol provision article for use in an aerosol provision system for generating an inhalable medium comprising an aerosol when a user draws on the aerosol provision system. The aerosol provision article includes a structure for transporting liquid from a liquid reservoir and heating the transported liquid to generate a flow of aerosol; and a region for receiving a substance which, in use, the flow of aerosol passes through and heats the substance before exiting the aerosol provision article, wherein the substance modifies a property of the flow of aerosol and wherein the structure is positioned so that when the structure heats the transported liquid to generate the flow of aerosol the structure also provides additional heat to the substance in the region.

## Claims

### Claim 1

An aerosol provision article for use in an aerosol provision system for generating an inhalable medium comprising an aerosol when a user draws on the aerosol provision system, the aerosol provision article comprising:
a structure for transporting liquid from a liquid reservoir and heating the transported liquid to generate a flow of aerosol; and
a region for receiving a substance which, in use, the flow of aerosol passes through and heats the substance before exiting the aerosol provision article, wherein the substance modifies a property of the flow of aerosol and wherein the structure is positioned so that when the structure heats the transported liquid to generate the flow of aerosol the structure also provides additional heat to the substance in the region.

### Claim 2 (depends on 1)

The aerosol provision article according to claim 1, wherein the structure comprises a substantially planar heating region for heating the transported liquid and the substance in the region.

### Claim 3 (depends on 2)

The aerosol provision article according to claim 2, wherein the substantially planar heating region faces the region for receiving the substance.

### Claim 4 (depends on 2)

The aerosol provision article according to claim 2, wherein the region for receiving the substance has a cross-sectional area that is substantially parallel with the substantially planar heating region.

### Claim 5 (depends on 1)

The aerosol provision article according to claim 1, wherein the structure is a wick.

### Claim 6 (depends on 5)

The aerosol provision article according to claim 5, wherein the wick is a mesh wick.

### Claim 7 (depends on 1)

The aerosol provision article according to claim 1, further comprising the liquid reservoir for containing the liquid.

### Claim 8 (depends on 1)

An aerosol provision system for generating an inhalable medium comprising an aerosol, the system comprising:
the aerosol provision article of claim 1; and
an aerosol provision device comprising a control for controlling the heating of the structure.

### Claim 9 (depends on 8)

The aerosol provision system according to claim 8, wherein the aerosol provision article and the aerosol provision device are releasably connectable together.
