This news is a wake-up call for women smokers, even the ones who smoke moderately.
The study carried out found that women who smoke just one cigarette a day carry a double the risk of heart ailments and sudden death. The research highlighted the enhanced risk of sudden death for light-to-moderate smokers compared to non-smokers.
A recent study conducted among 1. 2 million women found that those who quit smoking by the age of 30 can completely offset their risks of dying prematurely due to heart ailments.
Dr Sandhu, of the the University of Alberta, Canada, said: "What this study really tells women is how important it is to stop smoking. The benefits in terms of sudden cardiac death reduction are there for all women, not just those with established heart disease. It can be difficult to quit. It needs to be a long-term goal. It's not always easily achievable and it may take more than one attempt."
