The assessment also highlighted how much life someone could regain if they quit smoking in 2025.
According to the findings, a smoker who smokes 10 cigarettes a day and quits on January 1st could prevent losing an entire day of life by January 8th.
They could extend their life expectancy by a week if they quit by February 5th, and a whole month if they stop by August 5th. By the end of the year, they could have saved 50 days of life, the analysis concluded.

Jackson further explained that continuing to smoke can lead to various health issues and a shorter lifespan.
She stated: “Some people might think they don’t mind missing out on a few years of life, given that old age is often marked by chronic illness or disability. But smoking doesn’t cut short the unhealthy period at the end of life.”
“It primarily eats into the relatively healthy years in midlife, bringing forward the onset of ill-health. This means a 60-year-old smoker will typically have the health profile of a 70-year-old non-smoker.”
The study’s authors also highlight the health benefits of quitting smoking at any age, making this a potentially great New Year’s resolution for 2025.
