A new analysis reveals that quitting cigarette smoking adds years to life expectancy regardless of the age at which an individual stops the bad habit.
The promising results come from observational studies in Norway, the United Kingdom, the United States and Canada, where researchers tracked the health of about 1.5 million adults for 15 years.
The smokers participating in the study, between the ages of 40 and 80, lost about 12 to 13 years of their life on average compared to non-smokers. However, people who quit smoking for ten years were able to reverse the risk of all-cause death associated with their old habits.
The risk of death from diseases directly related to smoking, such as stroke, heart attack or cancer, has also been reduced.
“If a smoker can kick this addictive habit for up to a decade, he or she may live almost as long as someone who has never smoked a cigarette in their life,” says public health scientist Prabat Jha, of the Center for Global Health Research at Unity Health Toronto. “.
Researchers explain that if a person at any age stops smoking for less than 3 years, he will likely avoid losing 5 years of his life. He may also avoid losing a decade of his life if he stops smoking for a decade.
The younger the smoker decides to make this change, the better his life expectancy gains.
“Many people think it is too late to quit smoking, especially in middle age,” Jha says. “But these results contradict that thinking. It is not too late, the effect is quick and you can reduce the risks, which means a longer and better life.”
Researchers say the risk of death from lung disease was not significantly reduced among former smokers, reflecting long-term, irreversible airway damage.
However, smoking cessation is still the best option available to improve lung health and function among smokers.
