Definitions

• the present invention relates, on the one hand, to a tobacco substitute for the production of smoking products and/or smoking product substitutes based on a mixture of plant parts, wherein the mixture comprises plant parts derived from Alchemilla vulgaris and/or Myrtus communis.
• the present invention relates to smoking products comprising a tobacco substitute as well as smoking product substitutes comprising a tobacco substitute.
• the present invention also relates to a method for the production of smoking products and/or smoking product substitutes in which a tobacco substitute based on plant parts is provided.
• the tobacco substitute is produced based on a mixture of plant parts. This means that the tobacco substitute is limited not only to the mixture of the plant parts per se, but that the tobacco substitute may also be an extract of the mixture of plant parts or that the tobacco substitute may comprise synthetic equivalents of the extract of the mixture of plant parts, etc.
• tobacco substitute refers to a material that can substitute for tobacco.
• Tobacco is a product that is derived from the leaves of the tobacco plant Nicotiana tabacum.
• Common smoking products such as cigarettes, cigars, pipe tobacco, etc. nowadays comprise tobacco.
• the tobacco is contained in a thin paper tube.
• a cigarette that is a smoking product according to the invention and therefore comprises a tobacco substitute in contrast to an ordinary cigarette, all of the tobacco or a part of the tobacco contained in the thin paper tube is replaced by the tobacco substitute.
• Common smoking products are further referred to as tobacco products. However, smoking of tobacco and tobacco products is harmful to health.
• Smoking has been scientifically established as carcinogenic, it adversely affects the skin, the blood vessels, the respiratory tract and the fertility, and it often causes cardiovascular diseases, etc. A number of chemical substances are also added during the production of tobacco products, making the smoke even more harmful to health. Moreover, smoking of tobacco products is not only harmful to those who smoke the tobacco products, but also damages the health of so-called passive smokers. Passive smokers are people who do not smoke tobacco products themselves, but inhale the smoke from tobacco products smoked by others nearby. Passive smoking is particularly problematic when tobacco products are smoked in poorly ventilated spaces.
• smoking of tobacco products is addictive, which often makes it difficult for the tobacco smoker to stop smoking tobacco products.
• the addiction to tobacco products is both physical and psychological.
• the physical component of the addiction is caused by the nicotine present in tobacco products.
• nicotine has a stimulating effect, and nicotine is therefore one of the main factors that makes smoking pleasant. It increases blood circulation to the brain, and when it comes into contact with certain brain cells, neurotransmitters such as dopamine are produced. All of this results in improved capacity to concentrate, better memory functioning, an activating and/or stimulating effect, and a feeling of well-being.
• the activating/stimulating effect that can be induced by smoking tobacco products is referred to as the nicotine kick.
• Nicotine can also have a relaxing effect resulting from increased neurotransmitter production and thus alleviate stress in the tobacco smoker. Moreover, whenever the concentration of nicotine in the blood decreases, this gives addicted tobacco users a craving to repeatedly smoke tobacco products in order to avoid the coming withdrawal symptoms and maintain the nicotine kick. Among other factors, this nicotine kick is caused by maintenance of high dopamine levels by nicotine. Nicotine inhibits an enzyme responsible for the breakdown of neurotransmitters such as dopamine. A high level of dopamine causes favourable sensations. As nicotine is broken down in the body, the amount of neurotransmitters decreases, and with it dopamine levels, which increases the craving for more nicotine and thus more tobacco products.
• Nicotine withdrawal symptoms usually disappear about 10 days after stopping smoking of tobacco products.
• the psychological component of the addiction is considered to be a behavioural addiction. This psychological aspect of the addiction chiefly depends on one's motivation for smoking. Smoking of tobacco products recalls the primary sucking reflex, and it is therefore satisfying in the same manner as a baby bottle or dummy in young children.
• tobacco substitutes are therefore substances used to suppress the craving for tobacco.
• the tobacco substitute (partially) replaces tobacco so that the tobacco substitute can be smoked.
• Smoking product substitutes comprise a tobacco substitute and are used to help people stop smoking, and may comprise, for example, chewing gum, sweets, oral sprays, patches, etc.
• EP 0616496 describes a tobacco substitute having a pleasant taste that helps to suppress withdrawal symptoms caused by psychological addiction to the smoking of tobacco products.
• This patent describes the use of plant parts as tobacco substitutes in smoking products and smoking product substitutes, wherein the plant parts are at least partly derived from Alchemilla vulgaris and/or Myrtus communis. This allows products such as cigarettes, cigars, pipe smoking products and rolling tobacco to be produced in which the tobacco is completely or partially replaced by the tobacco substitute.
• smoking the modified cigars and cigarettes comprising the tobacco substitute makes it simpler/easier to overcome the psychological addiction to smoking tobacco products, because after a certain period of smoking these modified cigarettes/cigars, which contain no nicotine, the smoker finds that smoking does not contribute to his/her quality of life, and that the subconsciously repressed motivations actually appear to be false.
• Smoking of ordinary tobacco products after smoking for example a cigarette containing the tobacco substitute, will even be experienced as unpleasant because the tobacco substitute causes impregnation of the taste buds and odour receptors, which distorts the taste of ordinary tobacco products.
• the tar content and carbon monoxide content of the smoke of the tobacco substitute described in EP 0616496 is much lower than the tar content and carbon monoxide content of tobacco smoke, and it is therefore much less hazardous to health.
• the additional use of plants not containing pesticides/insecticides does not cause dioxins to be released.
• ordinary tobacco contains pesticides/insecticides comprising chlorine compounds. The burning of these pesticides/insecticides causes the release of dioxins.
• the tobacco substitute described in EP 0616496 does not deal with the problem of physical addiction to smoking of tobacco products, which is primarily an addiction to nicotine. In the first few days after stopping smoking, it is the addiction to nicotine that causes smokers to go back to tobacco products because the need for nicotine is too great, and this need is not suppressed by the tobacco substitute described in EP 0616496.
• the object of the invention is to find a tobacco substitute that can be used in the production of smoking products and/or smoking product substitutes, wherein these smoking products and/or smoking product substitutes help to suppress the need for nicotine, and therefore the withdrawal symptoms caused by the physical addiction to tobacco products in order to make it easier to stop smoking tobacco products, and wherein the taste of the tobacco substitute is pleasant.
• a tobacco substitute for the production of smoking products and/or smoking product substitutes based on a mixture of plant parts, wherein the mixture comprises plant parts derived from Alchemilla vulgaris and/or Myrtus communis, wherein the mixture comprises at least 5% by weight of caffeine-containing plant parts, and wherein the caffeine-containing plant parts are substantially derived from Ilex paraguayensis and Thea sinensis.
• the tobacco substitute is not produced on the basis of plant parts of the tobacco plant, and therefore comprises neither tobacco nor nicotine. With people who wish to stop smoking tobacco products, it is important to suppress the craving for nicotine and the craving for the nicotine kick in the first few days after stopping smoking of tobacco products.
• the tobacco substitute is produced on the basis of a mixture of plant parts comprising caffeine-containing plant parts, and therefore contains caffeine.
• Caffeine is also referred to by the names theine, mateine, and guaranine.
• caffeine has effects on the human body that are similar to certain aspects of the effects of nicotine, caffeine helps to suppress the craving for nicotine.
• caffeine increases blood circulation, and therefore also blood circulation to the brain, resulting in improved ability to concentrate and an activating/stimulating effect, as well as a reduction in appetite.
• a considerable part of the nicotine kick is replaced by a caffeine kick. Because the mixture comprises at least 5% by weight of caffeine-containing plant parts, caffeine is present in said mixture in an amount sufficient to suppress/alleviate the craving for nicotine.
• Caffeine is absorbed by the body during smoking of smoking products that comprise the tobacco substitute or during the use of smoking product substitutes that comprise the tobacco substitute. When smoked, caffeine is absorbed in forms such as vapour. Because of this, the caffeine is absorbed directly into the blood vessels via the respiratory mucosa, so that quite small amounts have a marked effect. Much lower concentrations of caffeine are therefore needed to obtain the same effect, compared for example to caffeine-containing energy drinks.
• Caffeine-containing plant parts are already used in certain tobacco substitutes. In these known tobacco substitutes, however, the caffeine-containing plant parts adversely affect the taste and aroma of the product. For example, the plant parts of Thea sinensis have an adverse effect on the taste and aroma of tobacco substitutes. Plant parts derived from Ilex paraguayensis also have an adverse effect on the taste and aroma of tobacco substitutes.
• both plant parts derived from Ilex paraguayensis and plant parts derived from Thea sinensis are used.
• the plant parts derived from Ilex paraguayensis neutralize the aroma and taste of the plant parts derived from Thea sinensis, and the plant parts derived from Thea sinensis also neutralize the aroma and taste of the plant parts derived from Ilex paraguayensis.
• the unpleasant aroma and taste properties of the plant parts per se are neutralized, and a caffeine-containing tobacco substitute is obtained wherein the caffeine-containing plant parts do not adversely affect the taste and aroma of the tobacco substitute.
• the addition of both caffeine-containing plant parts therefore has only a favourable effect, namely that of making caffeine available in order to suppress the craving for nicotine.
• smoking products/smoking product substitutes that comprise tobacco substitutes based on a mixture of plant parts comprising caffeine-containing plant parts constitute a highly effective aid, because smoking or using these products makes it less likely that the person will return to using tobacco products. This is because the presence of caffeine suppresses and alleviates the craving for nicotine.
• the nicotine withdrawal symptoms experienced by a tobacco smoker in the period after stopping smoking tobacco products are therefore sharply reduced with the aid of the tobacco substitute according to the invention.
• the caffeine is rapidly absorbed via the smoke in vapour form by the mucosa, allowing it to produce strong and short-term stimulation.
• caffeine has effects on the human body that are similar to certain aspects of the effects of nicotine, but without the addictive properties of nicotine. Once a nicotine kick is no longer needed, the need for another caffeine kick is therefore minor, and can be satisfied if necessary with a cup of coffee.
• smoking products and/or smoking product substitutes comprising a tobacco substitute that is based on plant parts including caffeine-containing plant parts is also reduced after the nicotine addiction is eliminated, specifically because caffeine is much less addictive than nicotine. After a certain period, it therefore becomes quite easy to stop using these smoking products and/or smoking product substitutes. It is also important to deal with the psychological addiction when stopping smoking tobacco products, because if the psychological addiction is neglected when stopping smoking tobacco products, this can cause tobacco smokers to relapse into their tobacco addiction, sometimes years after stopping the smoking of tobacco products.
• the mixture also comprises plant parts derived from Alchemilla vulgaris and/or Myrtus communis.
• the tobacco substitute is produced on the basis of a mixture of caffeine-containing plant parts and plant parts of Alchemilla vulgaris and/or Myrtus communis.
• the tobacco substitute is also effective in additionally helping to eliminate the psychological addiction.
• tobacco smokers will find it pleasant and agreeable to smoke a tobacco substitute based on plant parts of Alchemilla vulgaris and/or Myrtus communis.
• the taste and aroma of the smoke from a mixture comprising plant parts derived from Alchemilla vulgaris and/or Myrtus communis is comparable to the taste and aroma of actual tobacco products.
• Plant parts derived from Alchemilla vulgaris and/or Myrtus communis are also capable of suppressing unpleasant tastes or aromas of plant parts derived from plants other than Alchemilla vulgaris and/or Myrtus communis. In this manner, the caffeine-containing plant parts have even less effect on the taste of the tobacco substitute.
• the tobacco substitute based on the mixture will be perceived as being mild (also referred to as blond or light). If the mixture comprises more than 90% by weight of plant parts derived from Alchemilla vulgaris with respect to the mixture of Alchemilla vulgaris and Myrtus communis or comprises only Alchemilla vulgaris, the tobacco substitute based on said mixture will be perceived as being very mild (ultra light).
• the tobacco substitute based on said mixture will be perceived as being rather strong. If the mixture comprises more than 90% by weight of plant parts derived from Myrtus communis with respect to the mixture of Alchemilla vulgaris and Myrtus communis or comprises only Myrtus communis, the tobacco substitute based on said mixture will be perceived as being very strong.
• the caffeine thus suppresses the craving for nicotine, and the plant parts of Alchemilla vulgaris and/or Myrtus communis suppress the psychological craving to smoke tobacco products.
• the behavioural habit remains satisfied together with the subconscious motivations that will be recognized to be false after a certain period without nicotine, with the result that a tobacco smoker who has switched to smoking products and/or smoking product substitutes, that comprise a tobacco substitute according to the invention based on caffeine-containing plant parts and plant parts of Alchemilla vulgaris and/or Myrtus communis, will no longer crave or have almost no craving to smoke tobacco products.
• Smoking/ingestion of these tobacco substitutes is not hazardous or much less hazardous to health than tobacco.
• tobacco smokers who do not wish to stop smoking tobacco products but would like to lead a somewhat healthier life can smoke smoking products in which a portion of the tobacco is replaced by a tobacco substitute as described above.
• a smoking product comprising a tobacco substitute based on a plant part mixture comprising plant parts of Alchemilla vulgaris and/or Myrtus communis, the smoker often finds smoking of ordinary tobacco products to be unpleasant.
• the tobacco product will have an unusual and rather unpleasant taste/aroma because the taste buds and odour receptors have been impregnated with the tobacco substitute, with the result that persons wishing to stop smoking tobacco products have a reduced relapse rate.
• a tobacco substitute based on a mixture of plant parts of Alchemilla vulgaris and/or Myrtus communis the addition of plant parts derived from Ilex paraguayensis and Thea sinensis has virtually no effect on the taste/aroma of the mixture of Alchemilla vulgaris and/or Myrtus communis.
• Tobacco substitutes based on a mixture of plant parts derived from Ilex paraguayensis, Thea sinensis and Alchemilla vulgaris and/or Myrtus communis are therefore highly effective in suppressing/alleviating both the physical and the psychological craving.
• Smoking/ingestion of these tobacco substitutes is not hazardous to health or considerably less hazardous than tobacco, with the result that there is (virtually) no damage to health during the period after stopping smoking, and therefore during smoking/ingestion of these tobacco substitutes. Moreover, it is only necessary to use these tobacco substitutes until the tobacco smoker is free of the tobacco addiction. This takes an average of 6 to 8 weeks.
• the mixture comprises at least 10% by weight of Althea officinalis leaves.
• the Althea officinalis leaves have a technically interesting leaf structure. This is particularly important for processing of the tobacco substitute. Specifically, these leaves allow the mixture of plant parts to be formed in a simple and rapid manner.
• the cut Althea officinalis leaves When these Althea officinalis leaves are cut to form the mixture of plant parts, the cut Althea officinalis leaves form a mass that is capable of holding in place the smaller parts, such as those derived from the leaves of other plants having a finer leaf structure.
• Thea sinensis leaves have this type of fine structure and therefore make it more difficult to process the mixture.
• processing of tobacco substitutes that constitute a mixture of plant parts per se and are used for example, in the production of cigarettes/cigars, etc. and/or rolling tobacco/pipe tobacco, etc., it is particularly important that processing take place in a favourable manner. For example, if the mixture is to be used in a cigarette, it is transferred onto the cigarette paper via a ventilated flow in the machine.
• Althea officinalis leaves are used in the mixture, the above risk is avoided without requiring extra compression, as these leaves form a mass that holds the smaller parts together. In order to take optimum advantage of the benefits of Althea officinalis, at least 10% by weight of Althea officinalis leaves must be present in the mixture.
• a tobacco substitute comprising a mixture composed of plant parts wherein the mixture does not comprise Althea officinalis leaves is less homogeneous and results in greater loss during production of the cigarettes and falling out after production of the cigarettes, particularly during handling of the packaging containing the cigarettes.
• the Althea officinalis leaves also contribute to the favourable taste of the tobacco substitute.

Further preferably, the leaves of Alchemilla vulgaris and/or Myrtus communis are used. These leaves are the most suitable for use in the mixture of plant parts as they do not cause any technical problems in drying, remoistening and then cutting into tobacco substitutes for use, for example, in cigarettes, cigars, etc. In the production of tobacco leaves are also used, such that the leaves of other plants can be dried, cut and processed in a similar manner to leaves of the tobacco plant.
