Public opinion regarding smoking and health has been of interest to polling companies since the 1940s – virtually since the beginning of modern-day public opinion polling. In this manuscript we document the rate of change in the public’s awareness and beliefs about smoking and health in North America (the United States and Canada). We report on four broad categories of opinions – public awareness of reports that smoking has been linked to lung cancer, belief that smoking is harmful to health and a cause of lung cancer, belief that smoking is a cause of diseases other than lung cancer, and belief about the health hazards of second-hand smoke.

北美公众对健康和吸烟的看法

自 1940 年代以来，民意调查公司一直对有关吸烟和健康的民意感兴趣——实际上是自现代民意调查开始以来。在这份手稿中，我们记录了北美（美国和加拿大）公众对吸烟和健康的认识和信念的变化率。我们报告了四大类意见——公众对吸烟与肺癌有关的报道的认识、认为吸烟有害健康和导致肺癌的信念、认为吸烟是导致肺癌以外疾病的原因，以及相信二手烟对健康的危害。
