Abstract
The invention relates to a coaxial smoking article, particularly a coaxial cigarette, comprising a coaxial rod of smokable material, which rod has an inner segment (,) of smokable material surrounded by a covering (,), around which covering is an outer segment (,) of combustible or thermally destructible/decomposable material, which outer segment is also surrounded by a covering (,). The combustible or thermally destructible/decomposable material of the outer segment contains no or only a very small proportion of spot-forming substances. Further, the coverings of the inner and outer segments are such that spot-forming substances in the inner segment are essentially unable to reach the outside of the covering. Hence, a cigarette having reduced potential for the production of spotting is so formed.
