  • Patent number: 5293883
    Abstract: The invention includes a non-pyrolytic cigarette, having an elongated tube of approximately the same, shape, dimensions, and weight of a traditional cigarette. The elongated tube contains two tobacco-filled chambers along its length and incorporates a filter at the end placed in the mouth of the user. The chambers contain pre-burned tobacco and unburned tobacco. A central air passageway communicates with the tobacco-containing chambers, and provides the taste, smell and sensation of a traditional cigarette as air is drawn through the tube and is delivered to the user. Additionally, a multiplicity of nicotine-containing ampules located within the mouth filter release liquid nicotine into the mouth of the user when pressure is applied to the filter.
