A non-smokable tobacco product comprises a rod-shaped element of cigarette tobacco with a filter element at one end and both enclosed by a tubular wrapper. The product is rendered unsmokable by a perforation extending through the wrapper of the tobacco or the filter element so that when air is drawn through the filter substantially all of the air enters through those perforations, there being insufficient air flow through the tip end to propagate normal cigarette combustion of the tobacco at that location or to permit any appreciable amount of smoke reaching the smoker's mouth. The product is rendered smokable by the user covering the perforated region of the wrapper by means of a strip, a sliding band, or a ring which blocks air flow through the perforations and thus converts the product into a self-made cigarette that can be smoked in the manner of a regular cigarette. |
