Overview

Abstract Introduction Despite regulations that forbid cigarette packages from displaying messages such as “mild,” “low-tar,” and “light,” many smokers still have misperceptions about “light” or “low-tar” cigarettes. One reason may be that tar amount displays continue to be permitted. This study examines whether removing tar delivery information from packaging reduces consumer misperceptions about “low-tar” cigarettes. Methods An online experiment was conducted in South Korea among 531 smokers who were randomly assigned to one of two conditions: with and without tar information on cigarette packages. Participants evaluated which type of cigarette was mildest, least harmful, easiest for nonsmokers to start smoking, and easiest for smokers to quit. Results Ten out of 12 chi-square tests showed that people judged the lowest reported tar delivery cigarette to be the mildest (p < .01), least harmful (p < .05), easiest to start (p < .05), and easiest to quit (p < .05)—less so in the “no-tar” condition than the “tar” condition. A higher level of misbeliefs about supposed low-tar cigarettes were found in the “tar” condition compared to the “no-tar” condition for all three brands (t = 5.85, 4.07, 3.82, respectively, p < .001). Regression analyses showed that the “no-tar” condition negatively predicted the level of misbeliefs after controlling for demographic and smoking-related variables (B [SE] = −.72 (.12), −.50 (.12), −.48 (.13), respectively, p < .001). Conclusions Banning reported tar deliveries from cigarette packages is likely to reduce smokers’ misconceptions about “low-tar” cigarettes. When reported tar deliveries are absent, smokers have inconsistent judgments about differently packaged cigarettes. Implications When cigarette packages depict lower reported tar number deliveries, participants erroneously perceive them to be less harmful than packages displaying higher tar numbers. These misperceptions of harm may prompt smokers who might otherwise attempt to quit smoking to instead consume cigarettes with lower tar deliveries due to the mistaken belief that they will reduce their risk.
