In a filter cigarette having a tobacco strand, a wrapping and a filter, the filter possesses at least one gas phase-active filter part which contains at least one gas phase-reducing substance. The gas phase-reducing substances are embedded in a filter material matrix. They are introduced in a quantity of at least 75 mg per filter and at least 5 mg/mm of the length of the gas phase-active filter part. The filter cigarette exhibits a filter ventilation of at most 30% (or of from 30% to 70%). The NFDPM value is between 4 and 10 mg/cigarette (or in the range of from 2 to 4 mg/Cigarette), as measured in accordance with ISO smoking conditions. The gas phase quotient Q1, defined as (&#x3bc;g of benzene per cigarette)/(mg of CO per cigarette) and measured in accordance with ISO smoking conditions, is less than 1.5, preferably less than 1.

Filter cigarette

The invention relates to a process for enhancing the filling capacity of tobacco, such as cut tobacco leaf or tobacco midribs, or tobacco additional material, by treating the tobacco material having an initial moisture of 10-30% with a treatment gas consisting of nitrogen and/or argon at pressures of 400 to 1,000 bar followed by a continuous decompression and subsequent thermal post-treatment of the discharged tobacco material. The filling density of the tobacco charge in the autoclave is greater than 0.2 kg/dm.
