This literature review was done to estimate the uses and effectiveness of carbon monoxide (CO) breath analyzers in identifying smokers and evaluating the role it can play in tobacco cessation programs. A web-based research on PubMed and Scopus from date of inception till 2016 was done for collecting data for the review. Our inquiry was limited to relevant articles with specific keywords. During the web search title and abstracts, 118 articles were screened for content and quality and 66 articles were selected to get an update on the desired information. As on date, there is enough evidence to prove the reasonably high sensitivity and specificity of CO analyzers in distinguishing smokers and nonsmokers. It also correlates well with smoking status. Its primary application is in validating smoking abstinence and as a motivational tool in smoking cessation programs. Due to its advantages over other biochemical assays, it is used in screening large population, in developing countries and in research. It can also detect pregnant women who are smokers and victims of passive tobacco exposure. However, it does possess limitations which have to be taken into account when using it. It can be concluded that CO analyzers are proven to have great potential and can be used as an adjunct in achieving the goal of combating tobacco addiction. It is cheap, noninvasive, gives immediate results, easy to use, and it can be self-administered by individuals. It should henceforth be considered as an invaluable tool for tobacco cessation programs.
