摘要： A cigarette comprises a tobacco rod and a multi-component filter comprising a bed of adsorbent and a flavor-releasing filter segment located downstream of the bed of adsorbent. In the preferred embodiment, the adsorbent is also flavor-bearing and comprises high surface area, activated carbon. As mainstream smoke is drawn through the upstream portion of the filter, gas phase smoke constituents are removed and flavor is released from the adsorbent bed. Thereafter additional flavor is released into the mainstream smoke as it passes through the flavor-releasing filter segment. Ventilation is provided to limit the amount of tobacco being combusted during each puff and is arranged at a location spaced downstream from the adsorbent bed to lower mainstream smoke velocity through the adsorbent bed. Preferably, the carbon bed comprises at least 90 to 120 mg or greater of carbon in a fully filled condition or 160 to 180 mg or greater of carbon in a 85 filled condition or better, which in combination with other features provides a flavorful cigarette that achieves significant reductions in gas phase constituents of the mainstream smoke, including 90% reductions or greater in 1, 3 butadiene, acrolein, isoprene, propionaldehyde, acrylonitrile, benzene, toluene, styrene, and 80% reductions or greater in acetaldehyde and hydrogen cyanide.

摘要： A composition for inclusion within a cigarette, cigar, pipe or smokeless tobacco. The composition can be included within the tobacco itself, a filter for filtering tobacco smoke once burned or even within the paper or wrapper surrounding the tobacco product. In the cigarette filter, be it internal or external filters, the antioxidant complex is capable of scavenging and neutralizing the free radicals emanating from the burning or heated tobacco and passing through the filter as the smoker inhales. The composition is also capable of reducing free radical damage to the oro-pharyngeal cavity, respiratory tract and lungs resulting from tobacco smoke. The composition includes glutathione and preferaby L-glutathione and green tea and/or grape seed extract.
摘要翻译：包含在香烟，雪茄，烟斗或无烟烟草中的组合物。组合物可以包括在烟草本身内，用于过滤一旦燃烧的烟草烟雾的过滤器，或者甚至在烟草产品周围的纸张或包装纸中。在香烟过滤嘴中，无论是内部或外部过滤器，抗氧化剂复合物能够清除和中和从燃烧或加热的烟草发出的自由基，并吸烟者通过过滤器。该组合物还能够减少由烟草烟雾引起的咽喉腔，呼吸道和肺的自由基损伤。组合物包括谷胱甘肽和优选L-谷胱甘肽和绿茶和/或葡萄籽提取物。
