Abstract

The present invention provides a solution to reduce the lingering smell in confined spaces associated with smoked filter tipped cigarette butts. Unlike other methods the invention does not require any active step by the smoker to activate any deodorising material. The present invention provides a smoking article incorporating a tobacco smoke filter element which exhibits in a passive manner a deodorising property even after smoking has occurred. The filter element incorporates a vapour phase absorbing material which is maintained substantially free from contact by the particulate phase of tobacco smoke, yet which is open to diffusion contact with the vapour phase of tobacco smoke both during and after smoking of the smoking article. <IMAGE>
