A balance of total water in the smoking of a cigarette is presented indicating theoretically calculated as well as experimentally determined quantities. Both groups of values are found to coincide to a large extent. As the quantity of the water of combustion of a given tobacco variety or tobacco mixture does not vary (Virginia: 314 mg per g of tobacco), changes of total water values are a function of the initial moisture content of tobacco only. Approximately 3 % of the total water leave the cigarette at its tip. Nearly 2 % penetrate the paper wrapping (without its burning ring), and 95 % escape from the incandescent end. The particulate phases of the studied smoke streams are poor in water, i. e. they include only 2 % of the total water, while the water content of the gaseous phases amounts to 98 %. The total water of a cigarette is found to be distributed among the particulate and gaseous phases of the various smoke streams as follows: mainstream smoke 3 %, glow stream 80.5 %, sidestream smoke 14.5 %, diffusion stream 2 % (maximum).
