Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Pictorial cigarette warning labels (PWLs) are thought to increase risk knowledge, but experimental research has not examined PWLs' longer term effects on memory for health risks. This trial tests memory for health risks immediately or after a six-week delay for US-representative adult smokers, US-representative teen smokers/vulnerable smokers, and Appalachian-representative adult smokers. In addition, the trial tests the effects of different warning label components and the consequences of memory for labels on risk perceptions and quit intentions.
