Abstract: The invention relates to a method of producing a tobacco product for smoking. In order to develop a novel tobacco product for smoking, the following method steps are proposed:a) a mixed mass of tobacco particles, starch or a starch-containing product as binder, and additives is produced;b) the mixed mass is compressed and plasticized in an extruder by the application of thermal and mechanical energy;c) pressurized steam is forced through the mixed mass so as to form channels;d) on leaving the extruder, the plasticized mixed mass, rendered porous by the channels, is expanded or foamed by the drop in temperature and pressure, hardened as a continuous, porous, cylindrical rod and cut to the desired lengths.
