ABSTRACT An insert is interposed between the tobacco containing portion and the filter tip of a cigarette. The insert is formed with a passage connecting the two sections. The passage is surrounded by an annulus with two diametrally opposed orifices between the passage and the orifices. Rings surround the insert over the area of each orifice. The rings fit loosely around the insert. The annulus is covered with perforated paper. In use a smoker who wants a mild taste puffs weakly while if he wants a strong taste he puffs heftily so that the rings close the orifices.
