The Adult Consumers of Tobacco Study (ACTS1) DCE dataset contains survey data from participants who completed the DCE survey. Participants included U.S. adults 18 years or older who were current established cigarette smokers at the time of the survey, stratified by e-cigarette use status (current e-cigarette users, former e-cigarette users, and those who have never used e-cigarettes). The ACTS1 DCE Methods Report describes sampling, data processing, and weighting procedures. The DCE Survey Programming and DCE Survey Codebook documents show the questions that were asked and their display logics.
