Women who quit smoking before age 40 will live up to 9 years

Women's lifespan can increase by 9 years if they quit smoking before age 40, however, they still face a 20% higher mortality rate than women who have never smoked.

This is the result of a study published October 27 in the British leading medical journal The Lancet.

The study was conducted with nearly 1.2 million women in the UK, suggesting that smoking throughout adulthood reduced the average life expectancy by 11 years.

Women who give up smoking habits before the age of 40 can increase their average life expectancy by 9 years compared to those who have never smoked.

Women who quit smoking before the age of 30 increased their life expectancy (about 10 years). However, research also warns that this does not mean that it is safe to continue smoking until age 40 before quitting.

According to the study, women who smoke in the next few decades will have a 1.2 times higher mortality rate than women who have never smoked.

The study is one of the most extensive surveys of the effects of smoking on the current generation of women. This study is part of a large survey of women in the UK between 1996 and 2001.

According to the researchers, women who smoke will have three times higher mortality rates than women who have never smoked. Even women who smoke less than 10 cigarettes a day will have a double death rate compared to women who have never smoked.
