A smoking article (2, 34, 38, 42, 44, 48) comprises: a combustible heat source (4) having opposed front (6) and rear faces (8); one or more airflow channels (18) extending from the front face (6) to the rear face (8) of the combustible heat source (4); an aerosol-forming substrate (10) downstream of the rear face (8) of the combustible heat source (4); a mouthpiece (14) downstream of the aerosol-forming substrate (10); and one or more air inlets (32, 36) located downstream of the rear face (8) of the combustible heat source (4) and upstream of the mouthpiece (14). The one or more air inlets (32, 36) are located between the rear face (8) of the combustible heat source (4) and a downstream end of the aerosol-forming substrate (10). In use, air drawn through the aerosol-forming substrate (10) enters the smoking article (2, 34, 38, 42, 44, 48) through the one or more airflow channels (18) and the one or more air inlets (32, 36) and at least some of the air drawn through the aerosol-forming substrate (10) comes into direct contact with a combustible portion of the combustible heat source (4). |
