Research articleSmoker Awareness of and Beliefs About Supposedly Less-Harmful Tobacco Products
Introduction
In the past decade, cigarette manufacturers in the United States have introduced and marketed a variety of so-called “reduced exposure” products.1, 2, 3 For example, in 2000, Vector Tobacco introduced Omni®, which promised exposure to fewer carcinogens than conventional cigarette brands. In 2001, Brown and Williamson Tobacco Company began marketing Advance®, which touted a new filter and different type of tobacco that reduced exposure to harmful chemicals in tobacco smoke. In 1996, RJ Reynolds Tobacco Company (RJR) introduced Eclipse®, initially marketed with claims of less secondhand smoke, and later with claims of reduced cancer risk. Philip Morris USA test marketed Accord®,4 an electrically heated cigarette that allegedly reduced exposure to toxins found in conventional cigarettes. Finally, in 2002, Vector introduced Quest®, a new line of cigarettes with varying levels of nicotine. The Institute of Medicine (IOM)4 reviewed the scientific evidence regarding these products and labeled them “potential reduced exposure products” (PREPs). The IOM committee expressed concern that PREPs could encourage smokers to continue smoking, entice former smokers to return to tobacco use, and even recruit nonsmokers to use these supposedly safer products.4
The IOM’s concerns underscore the importance of consumers’ perceptions in the overall evaluation of PREPs. To date, however, there have been relatively few efforts made to document consumer awareness, beliefs, and use of PREPs. Shiffman et al.5 surveyed 1000 current cigarette smokers to ascertain their opinions about RJR’s Eclipse product. Respondents were read descriptions of the product based on advertisements and asked to rate their interest in purchasing Eclipse, and the perceived risk from Eclipse compared to smoking regular cigarettes. Respondents were also asked whether Eclipse might affect their decision to stop smoking. After hearing the description of the product, 57% of smokers said that they were at least somewhat likely to purchase Eclipse in the next 6 months. Nearly all current smokers (91.4%) believed that Eclipse was safer than smoking regular cigarettes, with 24% believing that Eclipse was completely safe based on the description from the advertisement. Although most smokers (60.3%) said Eclipse would not change their plans about quitting, 21.4% of those smokers contemplating quitting in the next 6 months lost interest in quitting after hearing about Eclipse.
Hamilton et al.6 conducted a mall intercept survey of 600 adult smokers to assess their reactions to advertisements for PREPs (Eclipse, Advance, Omni), light cigarettes, and regular cigarettes. Since none of the PREPs were being marketed in Massachusetts at the time of the study, respondents’ ratings about the relative health risks of PREPs were based solely on the advertising they were exposed to in the study. Respondents consistently rated the PREPs as having lower health risks and lower carcinogens compared to light and regular cigarettes.
Data from a 2002 U.S. national survey7 of smokers found that one third of smokers had heard of at least one supposedly less-harmful product when read the names of a series of such products. However, little is known about whether smokers who are not prompted with product names or given product information are aware of supposedly less-harmful products or have beliefs concerning their safety compared to smoking. Additionally, no surveys have compared knowledge of modified cigarettes and cigarette-like products to knowledge of smokeless tobacco (SLT), another class of products that could potentially reduce smoking-related health risks.
This paper reports data from the U.S. arm of the 2003 wave of the International Tobacco Control Policy Evaluation Project Four-Country Survey (ITC-4), a nationally representative sample telephone survey of 2028 adult smokers. This study reports data from questions that measured awareness of and beliefs about the risks of supposedly less-harmful tobacco products (including SLT). Smokers’ beliefs about alternatives to conventional cigarettes were examined.

Survey Description
The random-digit-dial (RDD) telephone survey of current smokers in the United States has been described in detail elsewhere.8 In brief, a sample of phone numbers in the United States was obtained from Survey Sampling International, which uses Random Digit Dialing B (RDD-B) methodology to generate number banks. The survey conducted in the United States was part of a larger international study involving parallel surveys conducted in the United Kingdom, Canada, and Australia. However, because
Awareness and Beliefs About Relative Safety of Supposedly Less-Harmful Cigarettes
Of the 2028 respondents, 784 (38.7%) said that they had heard about supposedly less-harmful products being marketed by cigarette manufacturers. Awareness of these products did not vary by respondent gender, but varied significantly with age. Of those aged ≥55, 51.0% were aware of such products, compared to 41.5% of 40- to 54-year-olds, 31.7% of 25- to 39-year-olds, and 23.7% of 18- to 24-year-olds (χ2[3]=68.26, p<0.001). Level of education was also associated with awareness of supposedly
Discussion
Approximately four in ten smokers said that they had heard about supposedly less-harmful products being manufactured by cigarette companies. However, only 27% of those aware of supposedly less-harmful products could name a specific product, and only 10% of the named products would be considered PREPs by the IOM.4 Smokers seem to be aware of the concept of “safer” cigarettes, although what they consider to be “safer” products was generally incorrect. Farrelly et al.7 found a similar
