Letterkenny General Hospital and the St Conal's Hospital Campus are to become completley smoke free from next week onwards.
From Thursday 13th September, no-one who enters the gates of the hospital will be allowed to smoke.
The HSE has set a target of introducing the tobacco free campus policy to all hospitals around the country by 2015.
The policy will be introduced at Letterkenny General Hospital and the St Conals Campus from next Thursday the 13th September.
From that date, no one will be permitted to smoke on anywhere on campus.
Management at Letterkenny General have said they aim to create a healthier, tobacco free environment for all patients, staff and visitors.
And the policy applies to all staff, patients, visitors, contractors and anyone who enters the hospital campus.
