A study conducted by the University of Toronto at Unity Health Toronto has shown significant life expectancy benefits for individuals who quit smoking, with effects visible within a few years.
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., 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 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.
Jha said the findings should add urgency to efforts by governments to support people who want to stop smoking. “Helping smokers quit is one of most effective ways to substantially improve health. And we know how to do that, by raising taxes on cigarettes and improving cessation supports.”
