SMOKING MATERIAL Russian patent published in 2010 - IPC A24D1/02 

FIELD: food industry.

SUBSTANCE: smoking material contains an overlay of a thin sheet material such as paper containing an adsorbent substance like activated carbon. The overlay is positioned near the outlet end of the smoking material to provide for more uniform profile of whiff in comparison with the common cigarette due to smoke components weakening during several final whiffs. The characteristics of the smoking material may be modified for increased smoke components delivery during several initial whiffs for maintenance of permanent outlet of nicotine and "dry resin" (NFDPM) in accordance with ISO standards.

EFFECT: adsorbent-containing paper covers only the smoking material part close to the outlet end and contains no flavouring agent.
