One of the region's hospitals has gone completely smoke-free.
A smoking ban has been put in place across the Addenbrooke's Hospital site in Cambridge.
From the start of 2014, people can no longer smoke anywhere on the site, whether they are inside or outside. It applies to all staff, visitors and patients.
– Dr Keith McNeil, Chief Executive Officer, Cambridge University Hospitals Trust
"It sends a message that we're not just about treating people's diseases here but we want society as a whole to be healthier.
It's very important from that point of view that we don't condone smoking on the site anywhere."_
The ban at Addenbrooke's and the Rosie Maternity Hospital is in accordance with national guidelines that all NHS hospitals should be smoke-free.
However, it has been difficult to enforce the guidelines in the past.
A previous attempt to ban smoking on the Addenbrooke's Hospital site proved unsuccessful.
The Queen Elizabeth and James Paget hospitals in Norfolk also tried going smoke-free, but the ban was largely ignored.
In the end, the hospitals built new smoking shelters.
However, the Cambridge University Hospitals Trust says it is confident it will now be able to enforce a smoking ban and encourage people to adopt healthier lifestyles.
