The present study was aimed to investigate the effect of smoking on the human blood glucose level of smokers and ex-smokers diabetic patients. Research design: This experiment was conducted on diabetic center on Libya included 80 healthy chronic smokers and 80 healthy ex-smokers people. Fasting blood sugar test performed on each subject. Results: Smoking acutely induces Fasting blood glucose level: the fasting glucose level of smokers was 127±3.36 mg/dl (mean±STD) during the smoking and 109±6.4 mg/dl in the ex-smokers (P< 0.05).. Conclusion: Smoking acutely increases blood glucose level These findings support the pathogenetic role of cigarette smoking on cardiovascular risk factors of diabetic patient.
