据WHO 报道,在瑞典,广泛宣传吸烟的危害后,从1975～1980年,吸烟者占人口比例由43%减少到37%。挪威1973年实行烟草管理法,到1982年,吸烟者由原来的52%减少到40%,加拿大由于提高香烟价格,香烟消耗量明显下降。美国吸烟人口比例也由1965年的42%下降到1980年的33%。控制吸烟的效果一般需要较长时间才能显示出来,据在欧洲的研究表明,1954～1977年,欧洲吸烟人数下降了21～43%,同时肺癌死亡率下降了25%。
According to the WHO, the share of smokers in the population of Sweden has been reduced from 43% to 37% from 1975 to 1980 after extensive publicity of the dangers of smoking in Sweden. In Norway, the Tobacco Control Law was introduced in 1973. By 1982, the smoker’s number was reduced from 52% to 40%. In Canada, the cigarette consumption dropped significantly due to the higher cigarette prices. The proportion of smokers in the United States also dropped from 42% in 1965 to 33% in 1980. The effect of smoking control generally takes longer to display. According to studies in Europe, from 1954 to 1977, the number of smokers in Europe decreased by 21-43% and the lung cancer death rate decreased by 25%.
