This clinical trial evaluates the acceptability and effectiveness of an educational intervention (Lung Toolkit) for improving knowledge about lung cancer and lung cancer screening among American Indian/Alaskan Native (AI/AN) cigarette smokers. The Lung Toolkit is an educational intervention, including a website and a physical artifact pouch, specifically tailored to the needs of AI/AN individuals. The website includes evidence-based resources about lung health and lung cancer screening, facts about commercial tobacco and traditional tobacco, national and local smoking cessation and screening resources, and community-building resources such as stories from AI/AN community members about their experiences with lung cancer screening and smoking cessation. The physical artifact pouch links to the website with a quick response code and contains ceremonial herbs and motivational messaging around smoking cessation and lung cancer screening. The Lung Toolkit intervention may be effective for improving knowledge about lung cancer and lung cancer screening among AI/AN cigarette smokers.
