A multi-component filter (4) for a smoking article comprises: a mouth end segment (12); a first flavour release segment (14)(28) comprising plant leaf upstream of the mouth end segment (12); and a second flavour release segment (16)(24) comprising filtration material and a flavourant upstream of the first flavour release segment (14)(28). The resistance to draw of the second flavour release segment (16)(24) is greater than the resistance to draw of the first flavour release segment (14) (28) and the resistance to draw of the second flavour release segment (16) (24) is greater than the resistance to draw of the mouth end segment (12). The multi-component filter (4) preferably further comprises a rod end segment (18) comprising filtration material upstream of the second flavour release segment (16) (24), which has a lower resistance to draw than the second flavour release segment (16)(24).
