Women smokers who quit by 30 'evade earlier death risks'

Women who give up smoking by the age of 30 will almost completely avoid the risks of dying early from tobacco-related diseases, according to a study of more than a million women in the UK.

The results, published in the Lancet, showed lifelong smokers died a decade earlier than those who never started.

But those who stopped by 30 lost, on average, a month of life and if they stopped by 40 they died a year younger.

Health experts said this was not a licence for the young to smoke.

The study followed the first generation of women to start smoking during the 1950s and 60s. As women started smoking on a large scale much later than men, the impact of a lifetime of cigarettes has only just been analysed for women.

"What we've shown is that if women smoke like men, they die like men," said lead researcher Prof Sir Richard Peto, from Oxford University.

He told the BBC: "More than half of women who smoke and keep on smoking will get killed by tobacco.

"Stopping works, amazingly well actually. Smoking kills, stopping works and the earlier you stop the better."
