Definitions

• the present invention relates to an antiviral and anticarcinogenic filtering element and to a smoke mouthpiece, in particular a mouthpiece for a nargile, adapted to house said filtering element. Furthermore, the present invention relates to an accessory device comprising the filtering element and applicable to the smoke mouthpiece, and to an antiviral and anticarcinogenic pipe for a nargile applicable to the smoke mouthpiece of the present invention, said smoke mouthpiece potentially being connected to the accessory device.
• the nargile often also called a shisha, hookah or water pipe, is an oriental pipe for smoking tobacco whose structure has been roughly the same for hundreds of years.
• each nargile essentially includes a container for water, a brazier for tobacco and a suction pipe.
• the smoker inhales the smoke through a special suction pipe which places in communication the water container where the smoke is generated and the mouth of the smoker.
• Smoking a nargile is a consolidated social custom in the Arab world, but has now also become fashionable among Western youths who increasingly often meet in evocative bars furnished with exotic tastes to share the pleasure of smoking tobacco aromatised with fruit which is usually used in a nargile.
• This "belief is connected both with the fact that the combustion temperature of the tobacco a the nargile is lower with respect to a cigarette (in the case of a nargile, the tobacco burns out slowly and indirectly through charcoal that burns at about 450 degrees, whereas in a cigarette the tobacco burns directly at a temperature comprised between 800 and 900 degrees), and with the presumed filtering effect of the water through which the smoke of the tobacco burned in the nargile passes.
• a further risk to which nargile smokers are exposed which has aroused much concern in the World Health Organisation is the transmission of pathogenic agents, of bacterial and viral origin, etc. through the saliva of smokers or however through the inhalation of the smoke by the smokers.
• the Applicant has found that, by applying the antiviral and/or anticarcinogenic filtering element to the smoke mouthpiece according to the present invention, it is possible to avoid the transmission of pathogenic agents from one individual to another associated with smoke, in particular with nargile smoke, and to substantially reduce the amount of carcinogenic substances that a smoker absorbs from tobacco smoke, in particular from nargile tobacco.
• the application of the antiviral and/or anticarcinogenic filtering element to the smoke mouthpiece according to the present invention is substantially advantageous for the purpose of reducing the risk of spreading diseases, whether they are caused by pathogenic agents such as viruses or bacteria, or caused by the carcinogenic substances contained in the tobacco. This result enables the large scale spread of disease to be prevented, i.e. it avoids pandemics and epidemics, and substantially reduces health care costs for individual countries and worldwide.
