ABSTRACT:
A multi-component filter for a smoking article comprises: a mouth end segment; a first flavor release segment comprising plant leaf upstream of the mouth end segment; and a second flavor release segment comprising filtration material and a flavorant upstream of the first flavor release segment. The resistance to draw of the second flavor release segment is greater than the resistance to draw of the first flavor release segment and the resistance to draw of the second flavor release segment is greater than the resistance to draw of the mouth end segment. The multi-component filter preferably further comprises a rod end segment comprising filtration material upstream of the second flavor release segment, which has a lower resistance to draw than the second flavor release segment.
