Assessing comprehension and perceptions of modified-risk information for snus among adult current cigarette smokers, former tobacco users, and never tobacco users

Abstract

The modified-risk information, conveying that snus presents less risk than cigarettes but is not completely safe, was understood by majorities of respondents. Differential risk beliefs across diseases suggest responses were shaped not only by the modified-risk information, but also by intuitions and pre-existing beliefs about tobacco products.
