Cigarette packs featuring images of cadavers, a field of tombstones or cancer-riddled mouths may indeed convince smokers to quit, a new study suggests, and those kinds of pictures may have a particularly strong impact on less-educated smokers who are less informed about health. "I'm not that surprised," said Aditi Satti, director of the Smoking Cessation Program and an assistant professor of medicine at Temple University Health System. "A picture is probably worth a thousand words in this type of patient,” she said.
