Abstract
The invention relates to a smoking article (1) having a high proportion of non-combustible, inorganic material and a relatively low level of visible sidestream. The smoking article includes a substantially non-combustible, wrapper (5) which extends along the full length of the smoking material rod and enwraps a combustible fuel source (6) and aerosol generator (7), both of which extend substantially along the length of the smoking material rod. Various suitable fuel source systems and aerosol generating systems are described. The article has a visible burn line which advances along the article and produces an ash which can be removed by the smoker in the normal way.
