Abstract
A tobacco smoke filter for cigarettes which presents initially relatively low pressure drop (54, 42) and relatively high pressure drop (40, 42) paths for the passage of smoke therethrough, the or each relatively low pressure drop having disposed thereacross a barrier (3) of material which is initially smoke-permeable but which is progressively blocked by the passage of smoke therethrough, whereby in use the initial preferential passage of smoke via the low pressure drop path or paths causes progressive blocking thereof so that the passage of smoke via the high pressure drop path or paths is correspondingly increased. <IMAGE>
