More smokers are packing in the habit in Cornwall but there are still about 80,000 who are refusing to quit.
Ten years ago 21% of people in Cornwall smoked, but this has now fallen to 15.7% according to research by the University College of London (UCL).
The report has been released as Cornwall Council and Public Health England launch the Stoptober quit smoking campaign.
Robert West, Professor of Health Psychology at UCL said: "Quitting success rates this year are soaring. The advances and wider choice in effective quitting options, and stronger anti-smoking culture are fuelling this acceleration."
