DETAILED DESCRIPTION

[0030] The smoking product for hookah according to the invention comprises, advantageously in decreasing order of importance in mass concentration, glycerin, propylene glycol, plant fibers other than tobacco and nicotine.

[0031] Glycerin or glycerol is in the form of a transparent, viscous, colorless, odorless liquid, slightly toxic if ingested, with a sweet taste. Its name according to the UCIPA nomenclature is 1,2,3-propanetriol CAS: 56-81-5. It is commonly available commercially.

[0032] Propylene glycol (PG), whose name according to the UCIPA nomenclature is propane-1,2-diol CAS: 57-55-6, is in a colorless, odorless, hygroscopic and viscous liquid form. It is also commonly available commercially. It is commonly used in many fields such as in the food industry as an emulsifier, in the cosmetic industry as a humectant.

[0033] In the field of application of hookah smoking products, propylene glycol, in particular in combination with glycerol, makes it possible to produce, once heated by the hookah charcoal, an aerosol simulating tobacco smoke.

[0034] Plant fibers other than tobacco may be fruit fibers, leaf fibers, bast fibers, cellulose fibers, cereal fibers, flower fibers, or any combination of these fibers.

[0035] Fruit fibers may include dried pieces of flesh with or without skin, and/or dried zest or skins of these fruits. These pieces, zest and skins can be obtained by cutting and/or grinding dried fruits.

[0036] Leaf fibers may include pieces of dried leaves, obtained by grinding the leaves in question. These leaves can be kaffir lime leaves, Indian wood, cinnamon, verbena, tea, hawthorn, agrimony, mugwort, boldo, Centella Asiatica, Cistus Incanus, eucalyptus, birch, damiana, raspberry, lemon balm, blueberry, dandelion, sana makki, Honeybush, Kinkeliba, mate, mint, Moringa Oleifera, lime, rooibos, bergamot, Yucca, Sisal (agave), Phormium, Mother-in-law's tongue, Henequen, Pineapple (pina), Abaca (banana leaves) and any combination.

[0037] Bast fibers can be obtained by cutting and/or grinding plant stems. These stems are advantageously dried beforehand. The fibers obtained by cutting and/or grinding can also be dried again. They may include fibers from linden, ramie, papyrus, nettles, flax, barrel creeper, kenaf, jute, Indian hemp, hemp (wool), and any combination.

[0038] Cellulose fibers can be obtained from cotton, wood, hemp, flax and sugar cane.

[0039] The plant fibers, and therefore the product to be smoked, may or may not include bagasse. Bagasse fibers are fibrous residues of sugar cane that have been crushed to extract the juice. They are composed mainly of cellulose from the plant.

[0040] Cereal fiber(s) may include bits of bran from the cereal in question. This bran, once dried, is crushed to form these pieces. The grain(s) are selected from the following list: wheat, oats, buckwheat, and any combination.

[0041] Flower fibers may also include pieces of dried flowers. The flower(s) are selected from the following list: rosebuds, chamomile, arnica, orange, cornflower, elderberry, Ginkgo biloba, hibiscus, clover, lavender, passionflower, and any combination. The flowers are advantageously fruit tree flowers, in particular apple trees, pear trees, etc. More generally, they are advantageously flowers capable of producing fruit.

[0042] These different types of plant fibers can be combined, in particular up to at least two or three types in question. By type of plant fibers, we can understand the different elements mentioned above, namely fruit fibers, leaf fibers, bast fibers, cellulose fibers, cereal fibers and flower fibers. By type of plant fiber, we can also mean a plant family, a plant genus or even a plant species.

[0043] Generally speaking, the plant fibers detailed above have a humidity level of between 5 and 30% m/m. They are cut and/or crushed so as to have an average main surface area of between 1 and 20 mm 2 and/or a main dimension of between 0.1 and 20 mm. They are present in the smoking product with a concentration of between 2% m/m and 50% m/m. [0044] fibers other than tobacco are advantageous in that they constitute a fuel releasing a limited quantity of carbon dioxide when heated.

[0045] Nicotine is advantageously of plant origin, extracted from tobacco. However, it can also be produced synthetically. It can also be a mixture of nicotine of plant origin and synthetic nicotine. The nicotine advantageously has a purity greater than or equal to 95%, preferably greater than or equal to 99%. Its name according to UCIPA nomenclature is (S)-3-(1-methyl-2-pyrrolidinyl)pyridine, CAS: 54-11-5, and its chemical formula is C10H14N2. It appears in the form of a hygroscopic, oily, yellow liquid with a characteristic odor, and turns brown on exposure to air.

[0046] Nicotine is an alkaloid that acts through inhalation, ingestion and contact. In the present case of hookah smoking products, the nicotine acts by inhalation. When inhaled, nicotine is absorbed by the blood capillaries of the lungs, passes the blood-brain barrier, and arrives in a few seconds in the brain without passing through the hepatic portal system.

[0047] The inventors of the present invention have observed that the combination of glycerin, propylene glycol, non-tobacco plant fibers, and nicotine in hookah smoking products provides brain passage pharmacokinetic effects that are similar to those of classic hookahs while significantly reducing the harmful effects linked to the inhalation of tars resulting from the combustion of tobacco.

[0048] The nicotine may be at a concentration of between 0.01 and 1% m/m, preferably between 0.05 and 0.7% m/m, more preferably between 0.15 and 0.3% m/m.

[0049] This nicotine concentration range was validated by consumption tests on a set of consumers, described below.

[0050] In order to obtain an objective and precise population within the framework of these tests, regular consumers of Hookah, of different sexes and ages were selected, namely: [0051] a group 1 of 20 people who consumed substitute products for traditional shisha tobacco and who were not satisfied and returned to traditional tobacco; [0052] a group 2 of 20 people consuming traditional shisha tobacco and having never tried substitutes; And [0053] a group 3 of 20 people very regularly consuming traditional shisha tobacco and having never tried substitutes, i.e. a total of 60 people who are used to consuming shisha with nicotine.

[0054] Consumers were invited to several shisha sessions during which hookahs containing Herbal Shisha products were prepared at different nicotine levels being 0.05%, 0.10%, 0.15%, 0.20%, 0.30%, 0.40%, 0.50%, 0.60%, 0.70%, 0.80%, 0.90% and 1.00%. Herbal Shisha includes, in addition to nicotine, glycerin, propylene glycol, plant fibers other than tobacco, in this case sugar cane bagasse. The hookahs were all prepared in the same way, by the same person and contained 15 g of Herbal Shisha product.

[0055] After each session, each consumer was asked to give a score out of 10 to the product they had tested in terms of sensation relating to nicotine, namely the hit (sensation of contraction of the larynx during the passage of vapor during inhalation) and possible side and/or unpleasant effects. A score of 0 corresponds to an unsatisfactory feeling, a score of 5 corresponds to an acceptable feeling and a score of 10 corresponds to a very satisfactory feeling.

[0056] The averages of the ratings of groups 1, 2 and 3 are shown in the graphs of FIGS. 1, 2 and 3, respectively.

[0057] We observe that preferential concentrations vary depending on the type of consumer. Taking into account these different types of consumers, we can however deduce from these results that the preferential nicotine concentration range goes from 0.05% to 0.70%.

[0058] It should be noted that a majority of testers appreciated being able to vary the percentage and therefore the intensity of nicotine in Herbal Shisha, which they cannot do when using traditional tobacco, because the levels are not communicated and that they would tend, for those who consume alone, to consume a lower level of nicotine when they do not consume the product in a social way and when they do not have to share the Hookah.
