NHS stop smoking services are having particular success in poor communities in the UK, a study shows.
Experts have found that of the 1.5 million smokers supported by NHS stop smoking services between 2003 and 2006, smokers from poorer areas used the services and successfully quit more often than those from wealthier communities.
Researchers from the University of Bath say quit smoking services are helping to reduce inequalities in health caused by smoking.
Dr Linda Bauld at the University of Bath said: "Smoking accounts for more than half of the excess risk of premature death between the highest and lowest socioeconomic groups in the UK.
"Our study shows NHS stop smoking services are helping to reduce the health gap between rich and poor, which is good news for the overall health of the nation."
She added, however, that it is still important that wider tobacco control measures such as a rise in tobacco taxes are still achieved.
The study was published in the journal Tobacco Control.
