A cigarette holder has an elongate tubular member, and includes a mouthpiece at a proximate end and a cylindrical receptacle at a distal end that is dimensioned to receive one end of a cigarette. A plurality of filters are axially spaced from each other along an intermediate portion of the holder to form air spaces between adjacent filters. Adjustable discs or rings are provided on the tubular member and are movable relative to a reference marking, one disc bearing time periods or intervals and the other disc bearing a maximum number of cigarettes that can be smoked in one time period, The discs or rings can provide cigarette reduction reminders each time period of the target number of cigarettes that can be smoked in each time period or interval.

Embodiments of the invention relate to a smoking and non-smoking aiding pipe having a bypass suction hole and, more particularly, to a smoking and non-smoking aiding pipe in which the introduction of harmful substances from a cigarette is delayed through a bypass suction hole, and harmful components having stickiness such as tar are removed by an adsorbing pad to minimize harmful components introduced into the human body, thereby minimizing damage to the body from smoking and providing a non-smoking effect in the long term.

This invention has multiple uses for smoking self-rolled cigarettes or the bigger ones called blunts made out of cigars or cigar rolling papers and even work as a paperless cigarette, paperless joint, or paperless joint. This embodiment has 4 parts of aluminum other metals or heat resistant materials may be used and 2 metal screens. A blunt or joint may be placed into the device to be used as a holder tube 2 that is cone shaped for adjustable fitting for joints, or smaller roller cigarettes or into tube 3 that is cone shaped for adjustable fitting for blunts, or larger roller cigarettes that protects the user from getting tobacco or legal marijuana into their mouth, it may also be used as a paperless joint, cigarette or blunt, by putting the tobacco or legal marijuana direct into the device in tube (3). It can also be used to store an unfinished hand rolled or paperless rolled cigarette, legal joint or blunt. It also supply a better smoke like one would get from a water pipe because of its built in filter with screen in tube (1).
