ABSTRACT:
A cigarette is provided with a cylindrical ungrooved filter plug which is surrounded by a ventilated tipping wrapper spaced radially from the plug by a slotted sheet laminated to the inner surface of the tipping wrapper. The slots communicate with the ventilated portions of the tipping wrapper and provide channels extending to the mouth end of the plug, whereby ventilating air is drawn into the smoker's mouth unmixed with smoke passing through the filter plug.
