Nearly 4,000 people were admitted to hospital in the Wakefield district with smoking-related illnesses in a 12-month period.
New estimates from Smokefree Wakefield reveal in the 12 months up to April 2013, there were ten admissions a day in people aged 35 and over.
Of the 3,953 admissions, 1,610 were related to cancer attributable to smoking and a further 1,214 related to respiratory problems caused by smoking.
Dr Andrew Furber, director of public health at Wakefield Council, said: “Smoking harms nearly every organ of the body and dramatically reduces both quality of life and life expectancy.
“It can cause lung cancer, respiratory disease and heart disease as well as numerous cancers in other organs including lip, mouth, throat, bladder, kidney, stomach, liver and cervix.
“While smoking is becoming less widespread it remains a leading cause of death and disease accounting for nearly 600 deaths a year in Wakefield.”
Coun Pat Garbutt, cabinet member for adults and health, added: “These figures show why it is so important for smokers to seek help in quitting.”
