risks of light smoking
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 one to four cigarettes
per day was associated with a significantly higher
risk of dying from ischemic 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 August issue of the journal Tobacco Control.
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
