An article for use with a non-combustible aerosol provision device includes an aerosol generating material), a mouth end section, and a tubular element, having a longitudinal axis, located between the aerosol generating material and the mouth end section. The tubular element includes an inner wall, and a ventilation area in the tubular element through which air is drawn into the tubular element. A component is received in the tubular element and the component has an outer surface and is configured so that aerosol flow through the tubular element is diverted into a flow path formed between the outer surface of the component and the inner wall of the tubular element. The ventilation area is configured such that ventilation air enters the flow path through the ventilation area to mix with the aerosol which is flowing along the flow path, before flowing into the mouth end section).

An article for use in an aerosol provision includes sections of aerosol-generating material coaxially aligned along a longitudinal axis of the article. A cross sectional area of each section transverse to the longitudinal axis is different. Also provided is a system including a non-combustible aerosol provision device, and an article having sections of aerosol-generating material coaxially aligned along a longitudinal axis of the article.
