摘要：
Cigarettes yielding substantially less sidestream smoke components than conventional cigarettes with similar delivery have a total length of 50 to 70 mm, a filter (2) from 19 to 28 mm long and a tobacco rod (1) having a packing density of 270 to 320 mg/cm³. The filter is secured to the tobacco rod in conventional manner by tipping material (3), which is impervious to air if no ventilating air is to be admitted, or may be air-permeable or perforated if ventilation is desired, for example up to a level of 60%.
