Numerous investigations and data on the development of smoke condensate and nicotine in German cigarettes, the changes in the market shares, the length of cigarettes smoked in laboratories and by the average consumer, and the per capita consumption of cigarettes in the Federal Republic of Germany were utilised in calculating the average delivery of smoke condensate and nicotine and for estimating the per capita consumption of moist and dry cigarette smoke condensate and the nicotine contained in it. In the period from 1961 to 1975 (for dry condensate figures are available only for 1966 to 1975) all these figures display a downward trend. Expressed in terms of the totaI population the reduction in moist condensate is about 31 %, nicotine about 40 % and dry condensate (for the shorter period 1966 to 1975) about 22 %. The percentages of smokers in the German population and among foreign workers, the development and age structure of the resident population and of the percentage of foreign workers were utilised to also ascertain from the above results the development of the condensate and nicotine consumption of the potentiaI and actual smokers. The result is again a reduction of consumption of approx. 36 % for moist condensate, of approx. 45 % for nicotine and 26 % for dry condensate (in the shorter period 1966 to 1975) a smoker. If these figures are converted to the equivalent of cigarettes of the type smoked in 1961 the consumption of 21 cigarettes a smoker established for 1975 corresponds to a mere 10 cigarettes of the type smoked in 1961. The actuaI daily consumption at that time, however, was about 15 cigarettes a smoker.
