Even light smoking triples disease death risk
One to four cigarettes a day can be deadly in long term, researchers say

LONDON - Smokers who believe a few cigarettes a day don’t do any harm will need to think again.
Norwegian scientists who studied the health records of 43,000 men and women have shown that even light smoking — less than five cigarettes daily — triples the risk of dying of heart disease or lung cancer.
“In both sexes, smoking 1-4 cigarettes per day was associated with a significantly higher risk of dying from ischaemic heart disease and from all causes, and from lung cancer in women,” said Dr. Aage Tverdal of the Norwegian Institute of Public Health in Oslo.
The study was published in the journal Tobacco Control.
The researchers tracked the health and death records and smoking habits of the men and women, who had been screened for heart disease at the start of the study, from the 1970s to 2002.
They found very little difference in the risk of dying from cancer, apart from lung cancer. Men who were light smokers were about three times more likely to die of lung cancer than non-smokers.
In women the risk rose to five times higher.
The dangers of smoking are well documented. Previous research has shown that smokers die on average 10 years earlier than non-smokers but kicking the habit, even in middle age, can the risk in half.
Smoking is also a risk factor for heart disease and stroke and raises the odds of developing age-related macular degeneration, which is the leading cause of blindness in the elderly.
Tverdal and his colleague Dr. Kjell Bjartveit, of the National Health Screening Service in Oslo and a co-author of the study, said health officials must emphasize more strongly that light smokers are also endangering their health.
