Lung cancer may be linked to timing of first cigarette

Updated:
A smoker's risk of lung cancer may be linked to when they light their first cigarette of the day.

Researchers looked at survey data from current and former smokers in the US and Italy - which included questions about how soon they had their first cigarette after waking.

Those who waited at least one hour to smoke were significantly less likely to develop lung cancer than those who began earlier.

The link was stronger among current smokers than in former smokers, and lighter smokers than heavier smokers.  There was no difference between men and women.

The study was led by researchers at the National Cancer Institute and published in 'JNCI: Journal of the National Cancer Institute'.
