Effect of Cigarette Constituent Messages With Engagement Text on Intention to Quit Smoking Among Adults Who Smoke Cigarettes A Randomized Clinical Trial
Source:
Question Do cigarette constituent messages with US Food and Drug Administration sourcing and engagement text (ie, encouragement to quit) increase intentions to quit more than cigarette constituent messages alone or control messages?
Findings In this randomized clinical trial of 789 adults who smoke cigarettes, participants assigned to the constituent plus engagement and constituent-only message conditions demonstrated increased quit intentions from preintervention to postintervention relative to participants in the control condition.
Meaning These findings indicate that messages about cigarette smoke constituents increased smokers’ intentions to quit, which can inform national efforts to communicate harmful constituents in cigarette smoke among adults who smoke.
