  • Smoking article
    Patent number: 4434804
    Abstract: Smoking articles, e.g. cigarettes, are disclosed into the fuel rod of which particulate smoke-modifying agent has been introduced in such a manner that the concentration of the agent is greater at one or each end of the fuel rod than that at the middle region of the fuel rod. The result of this variation in concentration of the smoke-modifying agent is that the amount of agent released into the smoke varies as the article is smoked. Various forms of smoking article are disclosed together with methods of production.
