Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvements in the modification of tobacco and filters.

[0002]

2. Description of the Related Art Tobacco smoke contains more than 2,000 kinds of chemical substances, of which about 200 harmful substances,
Forty or more carcinogenic substances are known. For this reason,
Recent tobacco tends to reduce tar and conitin in order to reduce the health harm of smoking. (A) Improving tobacco leaves to produce low nicotine leaves, (B), attaching filters to tobacco, (C), adding activated carbon to filters, (D) , Put a perforation around the filter,
When smoking a cigarette, air is taken in from outside through perforations to reduce the smoke of the cigarette. All of these methods (1) impair the taste of tobacco. Nicotine is the biggest factor in tobacco flavor, and low-conitine cigarettes feel unsatisfactory and eventually increase the number of cigarettes smoked. This increases the amount of other harmful substances, such as carbon monoxide, acetaldehyde, and formaldehyde, which are compounds generated when organic substances are burned, in the body. (2) Tobacco has recently added a fragrance without exception in order to compensate for the decrease in flavor due to low tar and low garnish, but this fragrance is harmful to human health when burning tobacco. There is no guarantee that no compounds will be formed. (3) The conventional filter bonded to tobacco is a two-stage filter consisting of a bundle of acetate fibers and a charcoal filter in which activated carbon fine particles are added in acetate fibers, which is bonded to the tip of the acetate filter. Most of the filters are structured. Particulate matter contained in cigarette smoke is filtered and removed by acetate fibers, and organic gaseous substance is absorbed and removed by activated carbon. Therefore,
If the volume of the filter is increased and the amount of activated carbon added is increased, the removal rate of these gaseous and particulate substances increases, but if the limit is exceeded, the flavor of tobacco is lost. (4) Charcoal smell is generated when activated carbon is added to the filter. (This is why tobacco with charcoal filters is not selling well in the United States and other countries.) If the amount of activated carbon added to the filter is increased,
Since a rich charcoal smell is generated, there is a limit to the amount of activated carbon added. (5) Conventional tobacco, when inhaled, receives a strong stimulus that sticks in the throat. This is because carbon monoxide, ammonia, and aldehydes such as formaldehyde irritate the mucous membrane of the respiratory tract. (These compounds are the leading cause of laryngeal cancer, and smokers have 20 times the incidence of laryngeal cancer than non-smokers). Most of these compounds, which are most harmful to human health, are not adsorbed and removed by the conventional filter attached to tobacco. Formerly the Central Research Institute of Japan Monopoly Corporation, in 1964, measured the adsorption efficiency of activated carbon for tobacco to gas-phase components in smoke, and published the results as shown in the following table. The filter used was a triple filter having a structure in which an activated carbon filter was interposed between acetate filters, and the amount of activated carbon was 100 to 120 mg.
(The amount of activated carbon added to a charcoal filter adhered to ordinary low tar, low nicotine tobacco is 50-60 mg). The adsorption and removal rate of formaldehyde, which is most harmful to the human body, is only 10%, and that of nitrogen peroxide (Nox) and carbon monoxide (CO) is 0%. (6) In the above-mentioned methods (A), (B), (C) and (D), any preventive prescription outside the body before harmful substances generated during the burning of tobacco are taken into the body. However, conventional tobacco does not take any measures after the harmful substances of tobacco are ingested into the body by smoking. Just be careful, "Be careful not to smoke too much as it may damage your health."

[0003]

Why do people smoke because they know that smoking is harmful to health? That's because nicotine can't stop stimulating the central nervous system. Experiments have shown that once nicotine is removed from a tobacco leaf, no one smokes the cigarette. Therefore, nicotine is essential for tobacco. To smoke is to consume nicotine, and it is inevitable that other harmful substances will be inhaled as a by-product. The present invention focuses on the pharmacological action of coffee, and attempts to suppress the action of nicotine toxins taken into the body by inhaling it together with tobacco smoke. In addition, the present invention removes more harmful substances contained in cigarette smoke more effectively without impairing the taste of cigarettes, relieves the irritation to the respiratory organs received when smoking cigarettes, and provides a filter of activated carbon. It seeks to eliminate the charcoal odor and reduce the health damage caused by smoking.

[0004]

[Means for Solving the Problems]

(1) The present invention relates to mixing or adding finely ground coffee beans into chopped leaves, or grinding and mixing and adding roasted coffee beans, or roasting. Add coffee extract extracted from roasted coffee beans. (2) The fine particles of roasted coffee beans are mixed into a filter, or activated carbon is activated by activating the coffee shell, and the activated carbon is mixed into the filter and adhered to a tobacco as a filter for tobacco. (3) Metal oxide or composite oxide is mixed and added to the tobacco filter.

[0005]

[Operation]

(1) Nicotine is the main alkaloid of tobacco. Tobacco includes, in addition to the main alkaloids, nornicotine, nico-telin, anabacine (a
nabasine), anatabin (anatabin)
e) and nearly 20 alkaloids are included and are structurally closely related to each other. Nicotine is highly toxic, _{LD 50} is 7.1mg. Nicotine is absorbed into the body through the lungs, oral mucosa, gastrointestinal mucosa, and skin. Nicotine absorption is the fastest in the respiratory tract and appears in the blood 7 seconds after inhalation and reaches the brain 10 seconds later. Nicotine that enters the body is metabolized in the liver, and metabolites are excreted from the kidneys. The half-life of nicotine in the body is about 40 minutes, which is fast compared to other addictive drugs. Therefore, the effect disappears quickly. The reason for smoking is to obtain stimulation of the central nervous system by nicotine. There are various substances that transmit a stimulus to a nerve, and acetylcholine (acetylcholine) is a nicotine-stimulated transmitter.
Plays an important role. Acetylcholine is a molecule in which acetic acid is bound to a substance called choline derived from vitamins. Acetylcholine is stored in secretory granules at the end of nerve fibers.When signals are transmitted from nerves, acetylcholine is released from these granules and binds to receptors on the surface of the next nerve cell to produce signals. Tell Acetylcholine, which has completed its role, is degraded by enzymes. Nicotine has conflicting duality of excitement and suppression. Nicotine has an excitatory effect on the central nervous system, vasoconstriction, blood pressure increases, and heart rate decreases. It then moves to suppression, where the heart rate is accelerated and the blood pressure falls. Peripheral excites the neuromuscular junction at first, then suppresses it. Chronic toxic symptoms from nicotine include irritation of the nasal cavity and bronchi, contraction of peripheral blood vessels and consequently decreased skin temperature, increased heart rate, increased blood pressure, increased blood sugar,
Urinary disorders, elevated fatty acids, and so on. (2) Many purine alkaloids isolated from plants have methylated nitrogen, and the representative ones are caffeine and theophylline contained in tea and coffee.
ylline) theobromine (theO-bromi)
ne). These alkaloids are xanthine derivative (xan-thine derivative).
e) is bonded to a methyl group (CH3) using skeleton as a skeleton.
Caffeine is a type of trimethylxanthine in which three methyl groups are bonded to xanthine. These alkaloids are the main components of excitable drinks that are widely consumed around the world. Caffeine is contained in cola, coffee, tea, guarana, and mate, and theophylline, which is dimethylxanthine, is contained in cocoa, tea, chocolate, and the like. Until now, caffeine has been ingested as a drink like coffee and tea, and has not been inhaled into the body as a gas phase substance by the respiratory route as in the present invention.
In other words, it was taken into the body as a drink or chewed food. Thus, caffeine is mostly absorbed in the intestine (partly in the stomach), blood, saliva, semen,
Appears in breast milk and body fluids. In the present invention, caffeine in the gaseous phase is inhaled together with tobacco smoke, so that it is absorbed by the lungs.
Thus, caffeine is absorbed faster than in the intestine and appears in the blood 7 seconds after inhalation and reaches the brain 10 seconds later. Taking caffeine refreshes your head and refreshes your mood. This is a so-called arousal effect. There are a number of substances that have arousing effects, one of which is adenosine (Adon)
sine) is involved in the arousal effect. Adenosine is
Adenine, one of the base components that serves as a source of nucleic acid information,
The ribose that constitutes one of the nucleic acids, RNA, is collectively called adenosine, which binds to three phosphates (triphosphates) to form A
Called TP. ATP is adenosine triphosphate (ade
abbreviation for nosinelliphosphate. Therefore, ATP is a compound that is a constituent unit of nucleic acid RNA, and is characterized in that three phosphate molecules are arranged in series. In humans and animals, the body is moved by contraction of muscles and generation and conduction of nerves. This energy source is ATP. The protein fibers of the muscle in the loose state are put into an over-energy state containing a large amount of high energy bonds by ATP. When given any stimulus, this energy is released and vigorously contracts. Some of the muscle protein fibers are turned into ATP-degrading enzymes. ATP released outside the cell is decomposed by this decomposing enzyme.
On the other hand, in neurons, a part of the cell membrane protrudes in a slender form, and turns into a fibrous neuron in the animal body. These nerve cells generate electricity at the cell membrane and transmit information along nerve fibers with electrical signals. There is a large difference in the concentration of sodium ions (Na ⁺ ) between the inside and outside of the nerve cell membrane. If any change is made to this, the balance of the difference in the concentration of sodium ions inside and outside the membrane is broken, and electricity is generated. It is a kind of density difference battery. The production and decomposition of ATP and the generation of electricity at the nerve cell membrane are indeed well designed. As the muscles move, the production of ATP is accelerated and the excess AT
P is released extracellularly. The released ATP drifts around the nerve cells and other cells. Neuronal and other cell membranes have adenosine receptors, AT
Binds to P adenosine. The binding of adenosine to the adenosine receptor suppresses the generation of electricity at the nerve cell membrane. When the generation of electricity is suppressed, the amount of ATP generated is also suppressed. When the amount of generated ATP is suppressed, the amount of released ATP is also suppressed, and the generation of electricity at the nerve cell membrane increases again. As the generation of electricity increases, the amount of ATP generated increases again. Such a chain reaction has occurred. The molecular structures of adenosine and caffeine are very similar. Adenosine and caffeine are based on a carbon / nitrogen bicyclic ring, the main difference being that the adenosine molecule binds to certain sugars. Somewhat small. Thus, the caffeine molecule readily binds to the adenosine molecule, and the adenosine molecule cannot bind to the adenosine receptor and is degraded by the enzyme. In that case, adenosine's inhibition on nerve cells stops working, but it doesn't.
The brain is surrounded by nerve cells that have many adenosine receptors. When the caffeine molecule binds to the adenosine receptor, a morphological deformation of the adenosine receptor occurs, and the chemical chain reaction that occurs when adenosine binds is not triggered. As a result, caffeine is no longer effective in suppressing adenosine, resulting in increased excitability in the brain. That is, caffeine acts as an indirect stimulant. Some nicotine is excreted as it is in breath and urine, but caffeine is rarely excreted as it is,
Circulates throughout the body until broken down by liver microsomal enzymes. The metabolism / decomposition of caffeine proceeds in the order in which the methyl groups are removed one by one in the enzyme. When the first methyl group leaves, it is converted to dimethylxanthine. The efficacy of dimethylxanthine is slightly stronger than that of trimethylxanthine. When one methyl group is removed from dimethylxanthine, it becomes methylxanthine, and when the last one is removed, xanthine has no stimulating action. Xanthine is excreted in the urine or partially recycled. As described above, the time required for metabolizing and decomposing coffee is much more complicated and longer than that for nicotine, and the half-life of caffeine in the body is 5 to 6 hours on average. During that time, it circulates through the body. In the results of animal studies, the effect of caffeine is biphasic. In experiments with mice, coffee with strong caffeine,
Up to a dose corresponding to approximately 3-4 servings, the higher the dose, the higher the activity. If the dose exceeds this value, on the contrary, the activity decreases. If the dose of caffeine is increased to 10 cups of coffee, the activity will be lower than before administration.
At least in mice, large amounts of caffeine act as inhibitors. Theophylline, one of the naturally occurring xanthines, has been the most effective substance ever used to treat asthma. The common pharmacological effects of xanthine derivatives are as follows. Excitation of the central nervous system and respiratory system, skeletal muscle excitation, diuretic effect, heart excitation, smooth muscle relaxation, etc.
Caffeine acts on the cerebral cortex to clear up thoughts (awakening action) and reduces sleepiness and fatigue. Theophylline is a substance used as a smooth muscle relaxant. Theobromine is used as an ethylenediamine salt in the treatment of cardiac edema and angina. Most smokers complain of sore throat. Sputum is caught and cough comes out. These symptoms are caused by some aldehydes such as formaldehyde and acetaldehyde contained in cigarette smoke irritating the mucous membrane of the throat. (Sore throat involves not only aldehydes but also ammonia and carbon monoxide). If this condition becomes chronic, the likelihood of suffering from bronchitis increases. Occasionally, edema (swelling) develops, compressing the bronchi. Xanthine derivatives cause relaxation of bronchial smooth muscle. Thus, bronchi and other respiratory organs damaged by smoking are exposed to xanthine derivatives in gaseous phase and have significant therapeutic effects due to the systemic circulation of xanthine derivatives. (3) Smokers have a much shorter half-life in the body of caffeine than non-smokers, averaging 3 hours. The mechanism is not fully understood, but it is estimated that smoking activates liver enzymes. In this case, since nicotine is not considered to activate the enzyme, PAH (polycyclic) generated during tobacco combustion is used.
It is considered that some reaction or synergism occurs between aromatic hydrocarbon (polycyclic aromatic hydrocarbon) and the caffeine component. The half-life of caffeine in the body about half means that some compound of PAH is consumed as metabolic energy for the metabolism of caffeine components. If you smoke, you want coffee, and if you drink coffee, you want cigarettes, as any smoker will experience.
It can be said that this was not merely a matter of taste, but a natural physiological need of the human body. (4) Nicotine ingested into the body
Is decomposed while consuming. Another name for vitamin C is ascorbic acid, which is the name recognized by the IuPAC-IUB naming committee. Ascorbic acid cannot synthesize ascorbic acid because humans, other primates, birds, and fish lack L-gulonolactone oxidase, and must take this vitamin from outside for survival. L-
The most prominent property of ascorbic acid (1) is its oxidation to dehydroascorbic acid (2). Ascorbic acid is a strong reducing agent and is therefore an oxidized, cheap and unstable substance, especially sensitive to heat. Dehydroascorbic acid is a powerful antioxidant and is widely used as a preservative for industrial applications. Vitamin C has an immunopotentiating effect and is used for prevention and treatment of infection. The large amount used for cold medicine is based on the immunopotentiating action of vitamin C. The effectiveness of vitamin C in preventing, treating, and controlling cancer has been recognized and is being studied by medical associations worldwide. In particular, the causal relationship between active oxygen and cancer development has attracted attention. Active oxygen is generated when tobacco is burned, and also when food is metabolized in the body. Vitamin C acts very effectively to eliminate these active oxygens. September 1997
Researcher Manami Inoue of the Aichi Cancer Center and his colleagues at the Japan Cancer Society held in Kyoto on May 25 reported that those who drink more than three cups of coffee a day are less likely to develop rectal cancer. I have. The effects of coffee are especially apparent on rectal cancer,
If the risk of rectal cancer is "1" for those who drink very little, "those who drink more than 3 cups daily" is 0.46, and the risk is less than half. A similar study was presented at a Swedish academic meeting in 1995. Given that most of the caffeine component is absorbed in the intestine, it is very implicit that those who drink more than three cups of coffee a day are less likely to develop rectal cancer. What happens when caffeine components are absorbed in the lung as in the present invention, in relation to lung cancer? . Until now, coffee was drinkable, so caffeine was absorbed in the stomach and intestine, but not in the lungs. Therefore, although there is no epidemiological investigation, it can be inferred that the occurrence of lung cancer due to smoking has a considerable effect by absorbing coffee components from the lungs. (Comparing non-smokers with habitual smokers, it is known from epidemiological studies that the incidence of lung cancer is 4.45 for smokers and 32.50 for laryngeal cancer when non-smokers are 1. There). In addition, it has been reported that vitamin C has a drug detoxifying action, fatty acid metabolizing action, and antioxidant action, and that vitamin C deficiency is observed in people exposed to various types of stress. In particular, it has been reported that vitamin C deficiency is remarkable in smoking stress. At the International Coffee Science Conference held in Kyoto from April 9 to 14, 1995, it was announced that chlorogen acid, which is one of the coffee components, has a high antioxidant effect. Masaki Omori has published experimental results on the degradation of coffee components and vitamin C. In a 0.1% aqueous solution of vitamin C, 0.05% of a control group, a fruit extract preparation, a tea extract preparation, and a raw coffee extract preparation which are not added at all are added, and after filling in an irradiation bottle,
After sterilization at 120 ° C. for 5 minutes, the mixture was stored at room temperature, and the amount of residual vitamin C was measured every 10 days. The experimental results are as shown in the table below. The test group showed a four-fold or more residual effect compared to the single-digit amount in the control group. It can be easily estimated from the above experimental results that the intake of coffee increases the residual ratio of vitamin C in the body. Thus, as in the present invention,
It can be estimated that simultaneous consumption of nicotine and caffeine has a remarkable effect on nicotine metabolism and decomposition. (5) Nicotine and caffeine are substances that are extremely easily absorbed in the body. Caffeine and nicotine carried to the brain by the blood stimulate the central nervous system. Caffeine has an average half-life in the body of 5-6 hours, which is much longer than the average half-life of nicotine in the body of 40 minutes. Therefore, its efficacy lasts much longer than nicotine. Caffeine and nicotine are identical in stimulating and stimulating effects on the central nervous system, but are completely opposite in other pharmacological effects. Nicotine is dependent, but caffeine is not.
The former slows down the work of the heart, while the latter increases the work of the heart. The former causes impaired blood circulation, while the latter improves blood circulation. The former causes dysuria, while the latter has a diuretic effect. The former raises fatty acids, while the latter has the effect of releasing and lowering fatty acids. It differs greatly in such points. Can these opposing actions cancel each other out like actions and reactions? . In some cases, "yes" can be said to be "direct" in the direct action, and in other cases, "yes" can be said to be indirect.
I can say that. Carbon monoxide binds to hemoglobin in the blood and inhibits oxygen transport. Deficiency in blood oxygen is a direct cause of angina attacks, but caffeine widens capillaries and increases blood circulation, supplementing blood deficiency. People with asthma cough violently when they smoke, and sometimes have seizures, but drinking coffee subsides. As a child, President Theodore Roosevelt was susceptible to asthma attacks. The attending physician recommended drinking coffee to reduce seizures. This was addicting and later I became a big coffee lover. It is said that his coffee cup was bigger near the tub. There is a strong causal relationship between smoking habits and the development of cancer,
It has been pointed out that a decrease in antioxidants such as vitamins A, C, and E causes the occurrence of cancer. It can be said that inhaling and ingesting tobacco and coffee together as in the present invention has an effect of counteracting nicotine toxin due to the antioxidant effect of coffee. What about bladder cancer, which is known to occur more frequently in smokers (85% of male bladder cancer is said to be due to smoking)? Initiation of bladder cancer is believed to be due to 2-naphthylamine. Caffeine molecule and 2-
How the naphthylamine molecule reacts and acts
I don't know well so far. We only know that caffeine has a diuretic effect. In this case, it can be said that there is no direct effect and some effect acts indirectly. (6) If fine particles of coffee beans or fine particles of roasted coffee are added to the cut leaves of tobacco, combustion heat higher than normal tobacco combustion heat can be obtained during combustion. Tar and carbon monoxide in tobacco smoke are produced by incomplete tobacco combustion. The combustion temperature of tobacco is usually around 800 ° C.
When the temperature is raised to 0 ° C. to 1,000 ° C., part of carbon monoxide is changed to carbon dioxide, and the amount of tar generation decreases with an increase in tobacco combustion temperature. Tobacco leaves are mainly composed of fibrous material, and in a dry state, when they start burning, they burn quickly. For this reason, humectants have been added to tobacco to make it harder to burn. Therefore, when the tobacco is burned, the organic component molecules of the tobacco and the water undergo a chemical reaction to generate a large amount of tar and carbon monoxide. Coffee beans are mainly composed of protein and fat, and burn with higher heat than tobacco leaves when burning. For this reason, carbon monoxide is converted into carbon dioxide by a thermal reaction, and the amount of generation of tar and nicotine is reduced. Instead, caffeine generated by the burning of coffee beans is contained in cigarette smoke. (7) In the present invention, activated carbonization by activating the roasted and crushed coffee fine particles or the coffee component extract or the coffee hull to the tobacco filter, and mixing and adding these to the filter is as follows. This is because all use the coffee's aroma, adsorption and deodorant effects. In general, when deodorizing, there are a method of adsorbing and removing odor molecules, and a method of masking odors emitted by other aromatics. The fine particles of the roasted and ground coffee are so-called semi-activated carbonized, and have a great effect of adsorbing and removing nicotine odor and charcoal odor of tobacco. Today, coffee husks, which are treated as industrial waste with the expansion of coffee consumption, are activated carbonized in the present invention and used for tobacco filters. The ability of activated carbon to adsorb and remove organic compounds need not be described here again. The aroma emitted by the roasted and ground coffee particles is rather intense and effectively masks the nicotine smell of tobacco and the charcoal smell of charcoal filters. (8) Carbon monoxide and formaldehyde, which are rich in tobacco smoke, are the most harmful to smokers' health. However, with conventional filters, carbon monoxide,
There is almost no effect of removing ammonia and formaldehyde.
In the present invention, a metal oxide or a composite oxide is mixed and added to the filter as a catalyst. In this case, the reactions of the following formulas (1) and (2) occur repeatedly on the catalyst surface. CO + MO −− → CO ₂ + M (1) 1 / 2O ₂ + M −− → MO (2) CO + 1 / 2O ₂ − → CO ₂ (3) = (1) + (2) * MO is a metal oxide M is a metal The state where the oxide is reduced. In the reaction (1), CO is oxidized to CO ₂ by the catalyst, and the catalyst is reduced. The reduced catalyst is reoxidized according to the equation (2). (1) + (2) gives equation (3), and (1)
Each time the reaction cycle of the formula (2) goes around once, one molecule of CO is oxidized to CO ₂ . Many metal oxide catalysts are used as composite compounds by mixing two or more oxides depending on the application, and their catalytic functions are complicated. As an example, when a small amount of Fe ₂ O ₃ or MoO ₃ is added to titanium oxide (TiO ₂ ) to have the property of a solid acid catalyst, the reactivity with NH ₃ increases. T by mixing with SiO ₂ and ZnO
Composite catalysts such as iO ₂ —SiO ₂ and TiO ₂ —ZnO have solid acidity and various PAHs (hydrocarbon compounds).
Works effectively on the decomposition of Further, for example, in the methanation of CO, CO + 3H ₂ − → CH ₄ + H ₂ O, the Ni / TiO ₂ catalyst using TiO ₂ as a carrier is used when Ni alone or another SiO ₂ or Al ₂ O ₃ is used as a carrier. It is known to have 10 times or more the activity in comparison. Further, for the adsorption of _{H 2} and CO, Ni, P
The effect of the SMSI between the transition metal such as t and TiO ₂ (strong metal-support int)
attention has been noted. In the present invention, the selection of the oxide catalyst to be added to the filter requires two contradictory properties that the bond adsorption energy with oxygen atoms is strong and that desorption is easy at the same time. It is not possible to use a material such as Ti) or iron (Fe), which has a strong bond with an oxygen atom and is hardly desorbed as a gas phase of CO ₂ or H ₂ O. Further, in the present invention, a mechanism is required which is provided with perforations around the filter and takes in air from outside the filter, as seen in a conventional filter. When a metal oxide or composite oxide is used as a catalyst, the activity of the oxidation reaction is generally governed by the activity of oxygen. On the oxide, the oxygen species that attack the oxide target include adsorbed oxygen and lattice oxygen (O ²⁻ ).
However, in the absence of oxygen, the oxidation reaction cannot occur in any case. As an example of the embodiment of the present invention, TiO ₂ alone, Ni / TiO ₂ , Ti
When a composite oxide such as O ₂ / SiO ₂ or TiO ₂ / ZnO is added to a cigarette filter, a large amount of hydrocarbon compounds (formaldehyde is also a kind), carbon monoxide, ammonia contained in the cigarette smoke It adsorbs and removes harmful substances such as tar and tar very effectively.

And so on. Although the effects of the present invention are wide-ranging, the last remaining problem is whether the flavor is not impaired or the smoker feels uncomfortable and does not cause rejection. . In the present invention, a female smoker who smokes more than 20 cigarettes a day for more than 5 years of smoking history
An experiment on the taste of the cigarette of the drawing "Fig. 1" described in the claim "Claim 1" of the present invention by selecting five male smokers who have more than 30 cigarettes and smoking history for more than 10 years a day. Was done. The experimental condition setting and its method are as follows. (1) The subject was not given the information of the present invention in advance. (2) Subjects were asked for 24 hours until the beginning of the experiment.
Alcohol, alcohol and other drugs were banned. (3) The tobacco subjected to the experiment had a tar content of 6 mg,
Using cigarettes with a charcoal filter having a nicotine content of 0.5 mg, the cigarette paper was removed from both the control and experimental plots, and the cigarettes were rewound so that they could not be visually identified. Perforations were made around the filter wrap. (4) Tobacco in the experimental section has coffee fine particles (particle diameter of 0.1 mm to 0.3 mm) roasted and ground in chopped leaves.
0 mg was added. (5) In the experiment, one control plot was sucked, and then one experimental plot was sucked, then allowed to rest for 15 minutes, and allowed to suck again. It was carried out. (6) Subjects were held in individual enclosures and prohibited contact with each other. The results of this experiment are as follows. (1) Those who answered that the taste of the tobacco in the control group and the experimental group were different: 1 female smoker and 1 male smoker, but how are they different?

(5) In the final experiment, after telling that the tobacco in the experimental area contained fine coffee particles, and asking them how they would like to taste it, he asked for the remaining one, except for male smoker 1. Said that the cigarettes in the experimental plot were "fresher in taste" and "fragrant." Needless to say that the above experiments need to be conducted on a larger number of smokers and more diversely, but at least as far as this experiment shows, the cigarette of the present invention,
No one felt uncomfortable or disliked it. In other words, the coffee component and the tobacco component contained in the cigarette smoke have an affinity and did not cause a rejection reaction to the smoker.
