The article includes a refillable liquid retention section and an aerosol-generation section located within a casing. The refillable liquid retention section includes a liquid retention medium, and the aerosol-generation section is located downstream of the refillable liquid retention section. The liquid retention medium has a capacity to absorb up to 35 microliters of liquid. The article is configured such that, during use, air can be drawn through the article from the distal end to the end, passing through the refillable liquid retention section.
