Camquit, Cambridgeshire's Stop Smoking Service, will be at The Rose Fair advising how quitting improves smokers' senses and reduces risk of disease.
Nearly 22 per cent of the population in Fenland smoke which is higher than any other district in the county.
Last year, over 500 smokers in Fenland who used Camquit were registered as successfully quitting after four weeks, reducing their risk ill health and early death.
Camquit will have a stall on Wisbech Market Place for The Rose Fair on Friday and Saturday 10am-4pm. For more information about giving up smoking, contact Camquit on 0800 018 4304 or at http://www.camquit.nhs.uk/
Claire Mead, Camquit Coordinator at Cambridgeshire County Council, said: "Smoking is a major risk factor for many illnesses including heart disease and cancer. But it can also affect the body in many other ways including reducing our sense of smell and taste. There are over 4000 chemicals found in cigarettes which damage nerve endings. Our ability to smell helps protect us against harmful smells such as a gas leak, fire or spoiled food. Just 48 hours after quitting smoking nerve endings start to regrow and sense of smell and taste begins to return to normal."
