`Chain smoking triples the risk of brain haemorrhage`
Smoking more than 20 cigarettes a day almost triples the chances of suffering a potentially fatal brain haemorrhage, a new study has warned.
The study found that quitting reduces the danger but heavy smokers who give up tobacco are still twice as much at risk as people who have never smoked.
Korean researchers investigated 426 cases of subarachnoid haemorrhage (SAH) between 2002 and 2004, the `Daily Mail` reported.
Patients were compared with a group of 426 people and matched for age and sex who had never experienced a brain bleed.
