Derbyshire County Council leaders have signed up to the Local Government Declaration on Tobacco Control as part of work to protect residents from the harm caused by smoking.
Every year in England, more than 80,000 people die from smoking related diseases.
In Derbyshire, between 2011 and 2013 around 3,900 adult deaths were attributable to smoking related diseases.
Although smoking rates are falling in the county, it’s estimated that over 113,000 adults still smoke in Derbyshire.
Derbyshire County Council’s cabinet member for health and communities councillor Dave Allen said: “Smoking remains the biggest cause of preventable illness and premature death.”
