Can sleep patterns explain racial gaps in smoking cravings?

This study investigates whether sleep duration and timing influence nicotine dependence, cravings, and withdrawal differently in Black and white smokers. Researchers will compare daily smokers and non-smokers, monitoring sleep with an Actiwatch and having participants undergo a sleep restriction condition (4 hours in bed) to see how it affects smoking urges. The goal is to understand if sleep disparities contribute to racial differences in smoking-related harms, which could inform more personalized cessation strategies.
