• Figure 1 is a side-on cross sectional view of an article 1 for use in an aerosol provision system.
• the article comprises a consumable for a non-combustible aerosol provision system.
• the article 1 further comprises an upstream component 4 at an upstream end of the article 1.
• the upstream component 4 includes a body of material 5 wrapped in a first wrapping material 6.
• the stability of the article 1, in use may be improved by the provision of the upstream component 4 at the upstream end of the article, by preventing fall-out of aerosol-generating material from the upstream end of the article.

At least part of the inner surface of the connecting wrapper 7 is covered by a layer of adhesive. It has been surprisingly found that applying a reduced amount of adhesive to the connecting wrapper 7 can result in the formation of an improved aerosol. This may be achieved by reducing the thickness of the layer of adhesive, or preferably by providing gaps in the layer of adhesive. Preferably, the layer of adhesive is discontinuous. For example, prior to combining the component 4 and the tobacco rod 2, adhesive may be applied to the connecting wrapper 7 in bands, such that the remaining portions of the connecting wrapper 7 are entirely free of adhesive.

• the bands of adhesive may extend in the same direction as the longitudinal axis of the article, perpendicular to the longitudinal axis of the article, or at another angle, such as diagonal to the longitudinal axis.
• Providing a discontinuous layer of adhesive on the inner surface of the connecting wrapper 7 may advantageously improve the ease of manufacture of the article 1, since less of the connecting wrapper 7 is wetted by the adhesive which can result in a higher tensile strength of the connecting wrapper 7 during manufacture.
• the adhesive layer may be applied in a different pattern, for instance a dot matrix.
• the connecting wrapper 7 has a permeability of at least 3 Coresta Units. In some examples, the connecting wrapper 7 has a permeability of at least 5
