ABSTRACT:
A tubular cigarette holder has a perforated barrier extending across its interior between the upstream cigarette receiving end of the tube and the downstream or outlet end. Ambient air is introduced in parallel with cigarette smoke through a passageway formed as one or more grooves in the inner wall of the tube at the cigarette receiving end. A rib formed on the inner wall in parallel with the groove indents the wall of the cigarettes to prevent cigarettes from entering and blocking the grooves. A tar collector depends from the barrier such that it will function to collect tar.
