  • Patent number: 4966169
    Abstract: A process for manufacturing cigarettes which imposes 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 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 solution. After the alcohol 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.
