"The report concluded that lung cancer and chronic bronchitis are causally related to cigarette smoking. The report also noted out that there was suggestive evidence, if not definite proof, for a causative role of smoking in other illnesses such as emphysema, cardiovascular disease, and various types of cancer. The committee concluded that cigarette smoking was a health hazard of sufficient importance to warrant appropriate remedial action.
"In June 1964, the Federal Trade Commission voted by a margin of 3-1 to require that cigarette manufacturers "clearly and prominently" place a warning on packages of cigarettes effective January 1, 1965, stating that smoking was dangerous to health, in line with the warning issued by the Surgeon General's special committee. The same warning would be required in all cigarette advertising effective July 1, 1965.

It also motivated the tobacco industry to intensify its efforts to question the scientific evidence linking smoking and disease. The report was also responsible for the passage of the Cigarette Labeling and Advertising Act of 1965, which, among other things, mandated Surgeon General's health warnings on cigarette packages" (Wikipedia article on Luther Terry, accessed 11-11-2012).
