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 separate 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 regulation.
在一项对 1836 名美国成年吸烟者的调查中，当使用直接比较衡量标准时，有 22.1%的人报告称鼻烟的危害小于香烟。当被间接询问（在两个单独的问题中估计鼻烟和香烟的健康风险，并将每个问题的答案相互比较）时，有 51.6%的人认为鼻烟的风险较低。当将感知风险数据作为烟草监管的证据呈现时，食品和药物管理局应同时考虑直接和间接措施。
