These hearings present opening statements which argue for the government's responsibility to protect the health of citizens, citing the dangerous and often fatal relationship of cigarette smoking to cancer and heart and lung disease. Statements include those from Mrs. Barney Clark, widow of the first heart transplant patient, and physicians, surgeons, and medical researchers. In addition, a number of published accounts of the danger of cigarette additives, such as deerstongue, are presented. Other testimony describes smoking prevention studies and warning labels that are used in other countries. Reports linking smoking-related illness in non-smokers to association with heavy smokers are also presented. Opposing testimony, presented by representatives of the tobacco industry as well as professionals from the fields of medicine, education, and psychology, proposes that people are sufficiently aware of the risks of smoking and that further federal intervention is unnecessary and would set an unwanted precedent. Additional testimony stresses that cigarette advertising is not aimed at young people, and evidence relating smoking to health hazards is not conclusive. The hearings include testimony from 17 witnesses; 42 prepared statements; and 13 additional articles, publications, and communications. (JAC)
