It was shown that cigarette smoking (CS) was a major environmental factor which effect on hematological parameters in healthy person (no clinical signs). Thus the current study aimed to assess the levels of some hematological parameters in 40 individuals who smoking cigarette and compared them to 20 non-smokers group. there was no statistically significant difference in age, gender, body mass index (BMI), waist/Hip ratio, Waist/Height ratio and blood pressure between the smokers and non- smokers. The results of the study revealed a statistically significant increase in total White blood cells, Red blood cells, lemphocyte count, neutrophil count and hematocrit, and there are a highly significant increase in mean corpuscular hemoglobin (MCH) and hemoglobin in smokers, But there are no significant differences in MCV, MID and PLT, when we compares the haematological parameters between smokers and non-smokers.
