ABSTRACT:
A smoking article which comprises a rod of smoking material contained within a wrapper has an air-permeability in a range of from 20 to about 120 Coresta units and is provided in the region of the mouth end, with ventilation means to give a degree of ventilation of 15 to 90%, the ratio of carbon-monoxide yield to tar yield of the smoking article being significantly less than 0.9. If the article has a tip means, the ventilation means may be provided, at least partially, in the tip means. The smoking material may include a high proportion of lamina-leaf tobacco having a relatively high nicotine content. Tobacco in the smoking material, possibly including stem tobacco, is coarsely cut or shredded. The smoking material may include up to 60% of expanded tobacco. The wrapper may contain an addition of a burn-promoting agent.
