What the Study Found (In Plain English)
The number one preventable cause of death in the world is tobacco use. Cigarette smoking in particular, costs an estimated $300 billion due to expenses related to medical care and lost productivity. Despite similar smoking prevalence rates, blacks suffer disproportionately from smoking-related harms compared to whites.Sleep disparities such as shortened sleep duration, shorter circadian periodicity, earlier chronotype, and increased variability of sleep timing have been reported more frequently in blacks compared to whites. Given that poor sleep quality predicts relapse from smoking cessation programs, particularly among socioeconomically disadvantaged adults, sleep deficiencies and irregular timing of sleep may impact smoking craving and w Registered in the U.S. National Library of Medicine ClinicalTrials.gov v2 registry (NCT03968900).

Study Limitations & Caveats Before You Act
While this completed human clinical trial (nct) scored 89/100 for research quality, clinical trials follow strict rules that may not match every patient's daily life. Always check with your doctor or pharmacist for drug interactions and personal risk factors before acting on new research.
