Show - It was not until a cigaret manufacturer manu-facturer started adding about ten j per cent sugar to tobacco that cigarets became popular. In curing cur-ing tobacco, almost all of the native na-tive sugar in the leaf is removed. The job that sugar does in tobacco to-bacco is to enhance moisture and serve as combustible material. In the process, it blends proteins and chemicals in tobacco as they burn so that a mild and pleasant acid smoke can be drawn into the mouth. At the light end, the smoke is alkaline, harsh and irritating. |
