The invention relates to a coaxial tobacco cartridge with an inner core of a first tobacco blend, a sheath for the inner core, an outer jacket of a second tobacco blend, a sheath of high air permeability and an associated filter element. The coaxial tobacco cartridge is not smokable independently, but can be used by persons to make their own coaxial cigarettes, by inserting it in an appropriate cigarette-paper tube or wrapping it in a cigarette-paper strip.
