  • Patent number: 5016655
    Abstract: A process for manufacturing cigarettes which impose reduced health risks to the smokers thereof. According to this process redried cut rag tobacco is directly sprayed with one or more pre-selected alcohols (or other compounds) which are capable, when the vapors thereof are inhaled by the smoker, of inhibiting or blocking the selective localization of at least one nitrosamine and/or a metabolite thereof in the smoker's tissues, such as those of the epithelial lining of his lungs. An example of such an alcohol is cyclohexanol in an ethyl alcohol soltuion. Other preferred alcohols are 3-methylcyclohexanol, 1-hexanol, 2-octanol and t-butanol. After the alcohol either directly or in a solution (such as a flavorant--SD alcohol-4 solution) has been sprayed on the tobacco, preferably as it tumbles in the cooler cylinder of the mechanized cigarette making line, and allowed to dry, the tobacco is made or machined in a conventional manner into the final cigarette, either filtered or unfiltered.

  • Patent number: 4967772
    Abstract: A tobacco smoking article including smoking tobacco held in a container and an alcohol supported by the container. The alcohol has two or more carbon atoms and is capable when the vapor thereof is inhaled by the smoker of inhibiting the selective localization of nitrosamines and metabolites thereof in the smoker's tissues, such as those of the bronchial epithelium. The alcohol is associated with the smoking tobacco such that, when the tobacco is smoked, the vapors of the alcohol are inhaled in the tobacco smoke stream. The alcohol is present in an amount sufficient to inhibit the selective localization but not to produce any toxic side effects in the smoker.
