Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The purpose of this study is to determine whether different cigarillo warning formats (pictorial, FDA-proposed text-only, current Surgeon General text-only) reduces demand for cigarillos. A previous study has identified that pictorial cigarillo warnings are perceived as more effective, but more information is needed on their impact. This study will address this issue by randomizing participants to see different cigarillo warning formats on cigarillo products within an online experimental tobacco marketplace. Participants will be cigarillo users who are ages 21-35.
