Smoking tobacco increases the brain bleed risk, even though quitting reduces the danger, but people with heavy smoking history, still have twice as much at risk as people who have never smoked, this report shows an investigation done by Korean researchers, they investigated 426 cases of subarachnoid haemorrhage(SAH) between the year 2002-2004, they were compared with a group 426 people matched for age and sex who had not had a brain bleed, in this study participants who have smoked are are more likely to suffer an SAH than non-smokers.
