Quitting smoking at any age brings big health benefits, fast: study:
People who quit smoking see major gains in life expectancy after just a few years, according to a new study by University of Toronto researchers at Unity Health Toronto.
The study, published in NEJM Evidence, shows that smokers who quit smoking before age 40 can expect to live almost as long as those who never smoked. Those who quit at any age return close to never-smoker survival 10 years after quitting, and about half that benefit occurs within just three years.
[...] Former smokers lowered their risk of death to 1.3-fold (or 30 per cent higher) compared to never smokers. Stopping smoking at any age was associated with longer survival, and even those who quit for less than three years gained up to six years in life expectancy.
"Many people think it's too late to quit smoking, especially in middle age," said Jha. "But these results counter that line of thought. It's never too late, the impact is fast and you can reduce risk across major diseases, meaning a longer and better quality of life."
The researchers found that quitting smoking reduced the risk of dying from vascular disease and cancer, in particular. Former smokers also reduced their risk of death from respiratory disease, but slightly less so, likely due to residual lung damage.
