EurekAlert: Doctors have known for years that smoking increases the risk of developing complications. Studies also show that smokers with diabetes have higher levels of HbA1c than nonsmokers with diabetes. However, nobody knew the exact substance in cigarette smoke responsible for the elevation in HbA1c. Liu and colleagues suspected it may be nicotine and set out to check nicotine's effects on HbA1c. Using human blood samples, they showed that concentrations of nicotine similar to those found in the blood of smokers did, indeed, raise levels of HbA1c.
