When healthy, these cells stimulate normal blood circulation by helping to prevent the buildup of plaque on blood vessel walls and formation of blood clots. The researchers found that blood flow of people who do not smoke "about 20 percent better than the blood stream of smokers. But after contact with cigarette smoke from others in just 30 minutes", their blood flow down to the level of blood flow smoker. According to researchers Dr.Ryo Otsuka, "this show direct evidence of the damaging effects of passive smoking on coronary circulation in nonsmokers."
