Perceptions of relative risk of snus and cigarettes among US smokers

In a survey of 1836 adult US smokers, when using a direct comparison measure, 22.1% reported snus was less harmful than were cigarettes. When asked indirectly (estimating the health risk of snus and cigarettes in 2 seprate questions and comparing the answers to each other), 51.6% rated snus as less risky. The Food and Drug Administration should consider both direct and indirect measures when perceived risk data are presented as evidence for tobacco regulations.
