Now that Stoptober is over, health officials have been doing some maths.
Public Health England estimates that:
The new ex-smokers could add as many as 4,700 years of life to the population as a whole.
With the average smoker using 13 cigarettes a day Stoptober would have saved them all £141 each. If they stay smokefree by Christmas they will save £423 and £1,696 over a year. Overall, Stoptober participants will have saved more than £34.5 million over the 28 days.
If smoking a cigarette takes 4 minutes on average, average smokers will have saved 24 hours each during Stoptober. Overall, that's 680 years of spare time gained.
Everyone who completed Stoptober is now 5 times more likely to stay smokefree for life.
Not too late to quit
Public Health England quotes Emmerdale actress and singer Kelsey-Beth Crossley who wanted to stop smoking to help protect her singing voice: "I did find the 28 days a real challenge - especially to begin with - but knowing so many other people were going through the same thing was really motivating and encouraging."
Public Health England says even though Stoptober has ended, it is not too late to try a 28-day smokefree challenge with help from the NHS, including through GP surgeries and pharmacies.
The next big date in the quit smoking calendar is New Year's Eve, when many more people are expected to choose giving up smoking as a New Year resolution.
