...first big gain, Drs. Wynder and Hoffmann find, comes from filters. "The smoker of filter cigarettes of 1964 is on the average exposed to approximately 50% less tar*and nicotine than he was while smoking cigarettes without filter tips ten years ago," they reported. Contrary to gloomy prophecies that smokers would cancel out the benefits of filters by puffing more of the newer cigarettes, the researchers found that in general this has not happened...
...other acids. A proportion of these (up to 90% in the case of phenol) can be removed by cellulose acetate filters. Other cilia-damaging components, such as acetaldehyde and acrolein, are cut down by an activated charcoal filter, especially if the charcoal is compressed. A still better way, said Wynder and Hoffmann, is to filter the smoke through water and then through compressed charcoal, but so far this is not practicable -except, conceivably, in homes with filter-tipped hookahs...
Surprisingly, tobacco stems yield less tar and noxious gases than the leaves. So, said Wynder and Hoffmann, there is less risk in smoking cigarettes if finely shredded stems are left in the tobacco, or if they are made from compressed sheets of homogenized tobacco dust and stems. Finally, finer cuts of the tobacco leaf itself make a less hazardous cigarette than the coarse cuts...
...cigarette smoking ever be entirely safe? Drs. Wynder and Hoffmann said they doubted it. They thought the only way to avoid the risks of lung cancer from smoking was not to smoke. But, they conceded: "Man may not always be willing or able to accomplish this objective." Therefore they urged more research toward producing "less hazardous" smoking products. "Considerable progress has been and is being made," they concluded. "Further advances are certainly feasible...
...scientifically correct term, but Dr. Wynder used it because everybody knows what it means when applied to cigarettes. t Although cigarette sales in the U.S., which dropped sharply after publication of the Public Health Service's report (TIME, Jan. 17), are almost back to pre-scare levels...
