Abstract
Abstract A cigarette holder having an attractive appearance and a compact structure suitable for use by ladies without any feel of reluctance, and capable of effectively removing nicotine and tar while permitting a visual check of the state of removal of nicotine and tar from the outside. A nicotine extractor made of a colored material, for removing the nicotine and tar by impact caused by collision of smoke, is fitted in a cigarette holder body made of a transparent material. When the colored nicotine extractor has become invisible from the outside of the cigarette holder body due to accumulation of nicotine and tars, the cigarette is no longer usable and can be discarded.
