  ABSTRACT: The aim of this study is to determine the effects of cigarette smoking on carboxylhaemoglobin (COHb) and calcium levels in apparently healthy male cigarette smokers in Benin City, Nigeria. Thirty active cigarette smokers and thirty healthy, non-smokers within the same age range participated in this study. Serum COHb level was estimated using ELISA reagent from Calbiotech, USA, while calcium concentration was estimated spectrophotometrically with commercially purchased kit from Randox, UK. Results showed higher concentration of COHb but lower concentration of calcium level among the cigarette smokers when compared with the non-smokers. There were no statistically significant differences observed in COHb levels between smokers with regard to smoking duration (
