As early as 1964 the Report of the Advisory Committee to the Surgeon General of the Public Health Service publi6hed by the
2 0 U . S . Department of Health, Education and Welfare 6tated at page 62 that "seven polycyclic compounds i601ated from cigarette smoke have been e6tablished to be carcinogenic ... The over-all carcinogenic potency of tobacco tar i6 many times the effects which can be attributed to 6ubstance~ isolated from it. The difference may be as60ciated in part with the presence in tobacco ~moke of cocarcinogen8, several of which hQve been identified a8 smoke component6, n At page 145 the report further ~tates that "one hypothesis suggests that promoting agents present in tobscco and tobacco smoke, such a6 various phenols, enhance the potency of
0 the carcinogenic hydro-carbons 80 a6 to account for the biological ~23~'7~
activity of the tobacco products. ~urther, possible synergism between low levels of the several non-carcinogens in the tobacco condensates and extracts may also enhance the carcinogenic potency. " The report goes on inventorying other noxious products 5 found in tobacco smoke such as pesticides used in the husbandry of tobacco in the United States, lactones and radioactive components. In an article published in the Los Angeles Herald Examiner of July 29, 1982, it is reported that the one and one-half pack-a-day smoker receives a yearly dose of alpha-radiation 10 equivalent to 300 chest X-rays - a dose to the windpipe area of some eight rems of radiation per year. By contrast, the government standard for total body radiation exposure for nuclear power plant workers is only 5 rems per year.
On the other hand, the HEW report states at page 74 that 15 "the effects of nicotine at dosage levels absorbed from smoking 0-2 milligrams (per inhaled cigarette) are comparatively small."
Countless attempts have been made over the last few years to reduce the tar content of smoking tobacco. Cigarette manufacturers commonly use comparative advertising showing the low-tar content 20 of their product relative to others. By judicious use of filters and other techniques, the tar content of certain cigarettes has been reduced down to the relatively low level of one milligram per smoked cigarette. Unfortunately, these techniques tend also to reduce the amount of inhaled nicotine to approximately 0.1 25 milligram per cigarette - thus forcing the smoker to use more than one cigarette or to take a deeper breath and hold it longer in the lungs in order to achieve the same effect as the one obtained from an unfiltered cigarette. In other words, no one ha~ found a wuy to completely eliminate the poison-louded smoke inhnlation inherent 30 in the combufition of tobucco without reducing or even eliminating at the same time the pleasing sensationæ derived from smoking, which are mainly attributable to the nicotine intake. To make matters worse, the filtering process tends to remove the largest but least harmful particles, while letting pass through smaller ones 35 which, because of their size tend to penetrate more deeply into the lung cells. Thus, we must face the paradox of an increase in the 123~73~

SUMMARY OF THE INVENTION
The present invention provides a means for allowing a smoker 35 to choose what is being inhaled, to adapt it to his health ~ ~ [)79~
_ 9 _ _ motivations, without having to fight against his habit to follow his physician's instructions. Thus, a smoker may inhale only tobacco smoke; a mixture of tobacco smoke and air containing nicotine;
tobacco-stimulating aromatics and antidotal metabolites; only air 5 containing nicotine, tobacco-stimulating aromatics and antidotal metabolites, or only pure air, with or without tobacco parfums.
As a result he may completely eliminate the noxious inhalation of tar and other poison-carrying smoke by limiting the intake to purified nicotine, tobacco-simulating aromatics and antidotal 10 metabolites. He may also completely eliminate the inhalation of nicotine, tobacco-simulating aromatics and antidotal metabolites by inhaling only pure air.
The nicotine, tobacco-simulating aromatics and antidotal metabolites are deposited in a volatile or sublimable form in the 15 air-intake channel of a smoking device. This channel is completely isolated from the combustion chamber by a non-combustible but heat-conductive wall. The smoke from the combustion chamber is not allowed to enter this air-intake channel. The combustion itself is used to provide the heat necessary to volatilize or sublime the 20 substances.
Any concern for the nearby non-smoker can be eliminated by replacing the tobacco by a pleasant-smelling aerated cellulose-based -combustible material, containing and surrounded by a tar absorbant like "carboadsorbons".
Smoking devices according to this invention may be implemented in various configurations. The air-intake channel can take the form of a chimney running through the center of a pipe bowl, a cigar or a cigarette. In an alternate confi~uration, the tobacco or substitute combustible material i8 held in a cupular 30 chamber whose peripheral walls are surrounded by a 6eries of channels converging toward the mouthpiece.
It is the principal object of this invention to provide a smoking device which enables the smoker to select various mixtures of air ranfing from normal tobacco smoke, to pure nicotine with its 35 antidotal tobacco parfums carrying air, or to pure air, with or without tobacco parfums.
~23079~
-Another object of this invention is to provide for the complete elimination of the inhalation of tar and other poison-carrying smoke, should the smoker so desire.
One advantage of this invention is that it provides a smoking 5 device which has the appearance, taste and feel of the common pipe, cigarette or cigar, and which preserves all the enjoyable, physiological effects due to the intake of nicotine.
An additional advantage of this invention is that it provides a means for alleviating the discomfort suffered by non-smokers 10 (called also "passive smokers") who find themselves in close proximity to a smoking individual in a confined environment.
A further advantage of this invention is that it improves the quality of the substances inhaled by the smoker by adding antidotal elements to the combination of purified nicotine and safe 15 tobacco-simulating aromatics.
These and other advantages of the invention are achieved by means of any and all of the various devices disclosed below.

DETAILED DESCRIPTION O~ THE PREFERRED EMBODIMENTS
ReferIsng now t~ the drawing~, ~nd specifically to F5gures through 4, a ~lr~t embodiment of the invention will be de~cribed.
This fir~t embodiment comprise~ a ~mo~dng pipe I comp~6ing a 5 head 2 and a 6tem 3 which has a 6tem conduit 4. The head 2 has a hole S at it~ bottom in which i6 inserted a metallic pipe-head obturator 6 having a 6pring 7. The pipe head 2 further contain~
a ~eries of holes 8 and screw-like threads 9 around it~ crown, and hss an interior wall 10.
The head 2 further comprise6 a dispo~able, ffre-re~istant and heat-conductive bowl 11 which is inserted in the head 2. The bowl Il is ~mmed by a flange overlap 12 having a series of peripheral holes 13 which match the holes 8 in the crown of the head 2. The nange overlap 12 slso contains a thread projection 14 which can be 15 threaded over the screw-like thread~ 9 of head 2. The level of bowl 11 in hesd 2 i~ adjusted by threading the projections 14 over threads 9. A hole 15 st the bottom of bowl 11 corresponds to obturstor 6. A bottom 6pace 16 i6 provided between the bottom of bowl 11 and the bottom of head 2 when bowl 11 is in an elevated 20 position as 6hown. A 6ide 6pace 16a al60 exists between head 2 snd bowl 11 when the bowl 11 i6 in6erted into the head 2. The construction of bowl 11 i6 more fully de6cribed in coPendin~

Volatile snd sublimable 6ub6tsnces which will vsporize when 25 the bowl 11 ~6 heated are impregnated in the porous 6urface of it6 out6ide wall6. These 6ub6tance~ are chosen to smell, taste and sct as would burning tobacco. They include nicotlne, tob~cco-smelling or tobacco-tAsting urom~tic~ ~nd untidotal metabolites auch as^ niacinamid. The tocation of thefie substance6 is more fully 30 described in U.S. Patent 4,474,191. These sub8tance6 Qre vaporized by the heat of combu~tion of the burning tobacco or tob~cco substitute.
Wlth reference to Figures 1 through 4, thi6 pipe embodiment can be used a6 follow6. It will be seen that the smoker i6 35 presented with four choice6 of inhaled air. In ~igure 1, the u6er 6crew6 the bowl 11, which i6 filled with tobacco, one-fourth of the way into pipe head 2. In this po~ition, pefipheral hsle6 13 and crown holes 8 are not ~igned and obturator 6 close~ bottom hole 5. As a re6ult, air i6 drawn only through the burning tobacco and pa~eE through hole 15 and through stem conduit 4 to the 5 u6er. In this position, pure tobacco 6moke i6 inhaled.

In Figure 9, tobacco load 40 is inserted into upper head half 32 and the composite is fully screwed into lower head half 32a. In this po~ition, peripheral holes 35, side holes 37 and end holes 3~ are closed. Holes 38 and 93 ar completely aligned. As a result, air is drawn only through the burning tobacco and passes through central tube 36 to stem conduit 34 to be inhaled by the user~ In this position, only pure tobacco smoke is inhaled.
In ~igure 10, the upper head half 32 is unscrewed one-fourth of the way out of lower head half 32a. In this position, peripheral 123 [)794 holes 35 and side holes 37 are closed. Holes 38 and 43 are now partially aligned and end holes 39 are open since they are separated from the edges of the central chimney 44. As a result, tobacco smoke which passes through holes 38 and 43 into central 5 tube 36 and air carrying vaporized nicotine and other substances which passes through chimney 44 and end holes 39 into central tube 36 are mixed and passed through stem conduit 34 to be inhaled by the user.
