Just four out of 10 people using the NHS Stop Smoking Service in Devon managed to quit, according to the latest figures.

In the six months from April to September last year, 1,400 people in Devon signed up with the NHS Stop Smoking Service and set themselves a date to quit.

At follow-up meetings four weeks later 600 people said they had given up, according to NHS England data.

That's 43 per cent, which is below the average rate for England of 51 per cent. The average for the South West was 44 per cent.

The success rate is based on self-reported results of people who said that they hadn't had a puff for two weeks since their quit date. But, 26 per cent of those who set a date proved they'd kicked the habit by having a test that checks carbon monoxide in their bloodstream.

The Stop Smoking Service offers support with one-to-one counselling or group sessions. Medicines that help with nicotine cravings can also be prescribed, while some people also use over the counter products.

In Devon, £506,000 has been allocated for stop smoking services this year, excluding the cost of medicines, down from £548,250 in the previous 12 months.

Over the six months, Devon spent £256,540, including drug costs, the equivalent to £428 for each person that quit.

In Devon, men had more success than women with 45 per cent quitting compared to 41 per cent of women.

Smokers aged 60 and over were most successful in quitting.

Latest Public Health England figures show that 14 per cent of Devon's adult population smoke.

Some local authorities no longer provide NHS Stop Smoking Services, and some did not supply complete data. Of 136 that did, the highest quit rate was 83 per cent in Rutland and the lowest was 18 per cent in Blackpool.

Rachael Hodges, policy officer at the British Lung Foundation said that smokers are far more likely to quit if they seek support.

She said: "Research shows that smokers are about four times as likely to successfully stop smoking when using a specialist service, and this has remained stable over recent years."

The service has been provided by local authorities rather than the NHS since 2013, but across the country funding is under threat as council's tighten their budgets.

Ms Hodges said the BLF wants more help for councils. She added: "We call for the government to increase public health funding to local authorities so they can continue to fund these vital services."
