ABSTRACT This short study enclosed a male category of Iraqis (343) divided into 2 groups one group contain smokers males (183) who smoke over twenty cigarettes per day and group of nonsmokers males (160), the mean age groups was (41 years), the predominant blood groups was O+ and B+, for each groups. The results of this study revealed statistically highly significant differences within the group of smokers ' body mass levels and blood lipid levels in distinction to those of the non-smokers with a propensity to have obesity within the category of smokers relative to the group of non-smokers, so blood lipid concentrations were higher in total cholesterol, triglycerides and LDL cholesterol rate in the smoker's community, and the HDL rate was lower. Whereas the body mass index for this study was a statistically highly significant regression towards the high proportion of obesity with high concentration levels of total cholesterol, triglycerides and low-density fats and a drop in high-density fat concentration levels.
