The Michigan Doily-Friday,.May 22 1981-Page-13 Cancer warning 'worn out' WASHINGTON (UPI) - Despite nearly two decades of bad publicity, 50 million Americans still don't know cigarette smoking can cause heart disease and two in 10 still don't know it can cause cancer, a government study said yesterday. The Federal Trade Commission staff report said much of the blame rests with warning labels on cigarette packages and advertising, both of which have become so "worn out" fewer than three percent of all adults exposed to them bother to read them. THE REPORT, given to Congress and released for six months of public comment, makes no specific recommendations. But it suggests one option might be to require a rotating series of warnings in adver- tising that might say "Heart Attack: A Major Risk Factor Is Smoking" or "Lung Cancer: The Major Cause is Smoking." The current warning label, required by Congress in 1965 and in advertising since 1972 by FTC order, says "Warning: The Surgeon General Has Determined That Cigarette Smoking Is Dangerous To Your Health." The report cites several surveys or studies, but most of the projections come from two commissioned by the FTC - a 1980 Roper study involving 2,000 in- terviews and a 1978 Gallup poll of 1,500 people. The commission has released a smoking report almost every year, and most have called for changes in warning labels. The difference this year, officials said, is that surveys for the first time reveal a gap in consumer understanding. WHILE MOST Americans are aware there is a health risk in smoking, many don't know exactly what the risk is or how it might affect them, James Sneed, head of the agency's Bureau of Consumer Protection, told a briefing. Sneed said while only Congress can change the cigarette label language, the FTC feels it has the power to require different warnings in advertising if it determines existing ads are false or deceptive. According to the study: -30 PERCENT of the public, or 50 million people, are "unaware of the relationship between smoking and heart disease." -Nearly half of all women ''do not know that smoking during pregnancy increases the risk of stillbirth and miscarriage." -Over 40 percent of people polled did not know smoking causes 80 percent of all lung cancer. -ABOUT 20 percent did not know smoking causes cancer. -About 60 percent do "not know that most cases of emphysema are smoking-related." -"Over 50 percent of the population does not know that smoking causes many, as opposed to just a few, cases of heart attack." -30 percent of the population and 41 percent of all smokers "did not know that a typical 30-year-old male shortened his life expectancy at all by smoking."
