"...Meeting at the National Library of Medicine on the campus of the National Institutes of Health in Bethesda, Maryland, from November 1962 through January 1964, the committee reviewed more than 7,000 scientific articles with the help of over 150 consultants. Terry issued the commission's report on January 11, 1964, choosing a Saturday to minimize the effect on the stock market and to maximize coverage in the Sunday papers. As Terry remembered the event, two decades later, the report "hit the country like a bombshell. It was front page news and a lead story on every radio and television station in the United States and many abroad.
The report highlighted the deleterious health consequences of tobacco use. Smoking and Health: Report of the Advisory Committee to the Surgeon General held cigarette smoking responsible for a 70 percent increase in the mortality rate of smokers over non-smokers. The report estimated that average smokers had a nine- to ten-fold risk of developing lung cancer compared to non-smokers: heavy smokers had at least a twenty-fold risk. The risk rose with the duration of smoking and diminished with the cessation of smoking. The report also named smoking as the most important cause of chronic bronchitis and pointed to a correlation between smoking and emphysema, and smoking and coronary heart disease. It noted that smoking during pregnancy reduced the average weight of newborns. On one issue the committee hedged: nicotine addiction. It insisted that the "tobacco habit should be characterized as an habituation rather than an addiction," in part because the addictive properties of nicotine were not yet fully understood, in part because of differences over the meaning of addiction.
The 1964 report on smoking and health had an impact on public attitudes and policy. A Gallup Survey conducted in 1958 found that only 44 percent of Americans believed smoking caused cancer, while 78 percent believed so by 1968. In the course of a decade, it had become common knowledge that smoking damaged health, and mounting evidence of health risks gave Terry's 1964 report public resonance. Yet, while the report proclaimed that "cigarette smoking is a health hazard of sufficient importance in the United States to warrant appropriate remedial action," it remained silent on concrete remedies. That challenge fell to politicians. In 1965, Congress required all cigarette packages distributed in the United States to carry a health warning, and since 1970 this warning is made in the name of the Surgeon General. In 1969, cigarette advertising on television and radio was banned, effective September 1970."
