Smoking is one of the three major risk factors for vascular disease along with hypertension and hyperlipidemia. It is true that smoking has a negative effect on the circulatory system, and the frequency of coronary artery disease and peripheral vascular disease is significantly increased in smokers. Many epidemiological studies report that smokers have an approximately two-fold increased risk of coronary artery disease compared to non-smokers. This study was designed to investigate the relationship between cerebral blood flow change and depression index after acute smoking. Cerebral blood flow tests were performed before and after smoking in 8 subjects. Changes in blood flow after smoking were correlated with the depression score and negatively correlated with the depression score. In particular, there was a strong correlation with changes in blood flow in anterior cerebral artery. It is well known that changes in blood flow after smoking have a negative effect. In addition, considering the study that smoking aggravates the symptoms of depression, it was found that smoking and depression are factors that negatively affect each other.
