A non-smokeable cigarette unit which may be rendered smokeable by application of a tubular sleeve to the cigarette filter region has a tobacco rod, a filter plug portion and connecting material for connecting the filter plug to the tobacco rod. At least a portion of the periphery of the filter plug is of a sufficient porosity to render the cigarette unit unsmokeable. The filter has a diameter less than the diameter of the tobacco rod. The connecting material bridges a transition from the smaller filter to the larger tobacco rod. This transition portion assists in sliding the sleeve onto the larger tobacco rod to provide a smokeable cigarette.

Make-your-own cigarette

Cigarette extinguishing storage device

A novel reconstituted tobacco sheet material is provided which is useful in providing a novel smoking product which has a smoking quality closely approximating that of cigarettes having conventional paper wrappers. The reconstituted tobacco sheet is prepared by a paper-making process in which the water-soluble material extracted in the paper-making process is not added back to the sheet, or if added back, to an extent of no more than 20 wt % of the reconstituted tobacco sheet. In the novel smoking product, a tobacco filler rod is enclosed within an outer wrapper, which usually comprises an inner binder layer and an outer wrapper layer, one or both formed of reconstituted tobacco sheet material. When the tobacco filler rod is double-wrapped, the novel smoking product also exhibits a significant reduction in sidestream smoking production in comparison to a conventionally-wrapped cigarette. The reconstituted tobacco sheet material has a porosity of at least about 50 Coresta units and contains about 0 to about 20 wt % of conventional chalk-type fillers.

Smoking product

A cigarette extinguishing and storage device is of tubular shape and provided by telescoping elements which define an enclosure in which a lit cigarette is received to extinguish the same and in which the extinguished cigarette is stored until the smoker wishes to relight the same. Charcoal or other suitable deodorant means is provided at the internal surface of the enclosure to absorb condensates from tobacco smoke. The device preferably is made of one or more plies of paper, so as to be disposable.
