Claim:
A tobacco smoking apparatus for use in smoking a cigarette, said tobacco smoking apparatus comprising: an enclosure that is configured for enclosing tobacco combustion activity; wherein said tobacco smoking apparatus is configured so that a user can both inhale combustion products from said enclosure and exhale combustion products into said enclosure; an air input port that is configured to input atmospheric gases residing outside of said enclosure when an internal gas pressure of internal gases residing inside of said enclosure is less than an atmospheric pressure of said atmospheric gases residing outside of said enclosure by a sufficient negative pressure value; and a gas output port that is configured to output internal gases and other combustion products residing inside of said enclosure when an internal gas pressure of said internal gases residing inside said enclosure is greater than said atmospheric pressure by a sufficient positive pressure value; wherein said tobacco smoking apparatus includes a movable cigarette holder for holding a cigarette, wherein said tobacco smoking apparatus is configured so that said movable cigarette holder holds a cigarette within said enclosure, said tobacco smoking apparatus being configured so that a user of said tobacco smoking apparatus can manually move said movable cigarette holder between a first position and a second position, wherein said movable cigarette holder when in said first position holds said cigarette so that a front end of said cigarette extends to a position external to said enclosure, wherein said cigarette holder when in said second position holds said cigarette so that said cigarette is entirely enclosed within said enclosure, and wherein said enclosure includes a port for use in inhaling combustion products, said tobacco smoking apparatus being configured so that when said movable cigarette holder is in said second position, a back end of said cigarette is closer to said port for use in inhaling than when in said first position.
