Smoking will be officially stubbed out at North Tees and Hartlepool NHS Foundation Trust from 1 August.
It means that smoking will not be allowed anywhere on trust premises.
The use of e-cigarettes is not currently permitted in hospital buildings or on the hospital site as they are not currently medically regulated products.
Medical director David Emerton said: “A smoking ban means that smoking is not allowed on site for patients, service users, staff, members of the public and contracted workers.
“As a healthcare provider, we should be encouraging a healthier lifestyle for the public, our patients and staff and smoking is not part of this.
“Quitting smoking isn’t easy and that’s why we’re here to help. We are committed to doing everything we can do to support staff and patients to successfully quit and would encourage smokers to go along to one of our stop smoking clinics which are run at convenient venues across Stockton, Hartlepool, Redcar and Middlesbrough.
“Quitting smoking has many benefits for patients who are coming into hospital for surgery too. Being smoke free before surgery means you will need less anaesthesia which means a shorter recovery time, it lowers your risk of chest infections, you will have fewer problems with bones and wounds healing after surgery, you will spend less time in the recovery room and have a shorter stay in hospital.”
