Smoking is common among adults of all ages. Decades of research have shown that smoking is linked to side effects such as lung cancer. This study aims to systematically review how smoking is linked to sleep. Database searches were done through Web of Science and Google Scholar. A total of 19 peer-reviewed journals were referenced to conduct this literature review. 15 peer-reviewed journals were used for the results. Results demonstrated that smoking was found to be correlated with sleep deprivation in both males and females of all ages. Environmental Tobacco Smoke (ETS) was a source of non-smokers' sleep complaints. Although there are multiple kinds of cigarettes, sleep quality has been shown to be poor regardless of the smoking medium. Ceasing smoking may lead to sleep benefits. Additional research will need to be conducted to further corroborate this statement.
