A Birmingham hospital is introducing a total ban on smoking on its premises from today.
Until yesterday staff and families who wanted to smoke at Birmingham Children's Hospital could do so in designated smoking shelters.
However the hospital's trust board decided in June to introduce a total ban.
This follows recent research which revealed that smoking is now more often associated with bad characters, rather than good, in films and on TV, reversing the trend of depicting smoking as being "cool" or socially acceptable.
A separate study - which was published last month - also strengthened the link between passive smoking around children and those who take up smoking in adulthood.
Paul O'Connor, the hospital's chief executive, said: "Our first concern is children's health.
"As leaders in child healthcare in this region we have a duty to protect our patients and sent an example.
"Although not wishing to remove an individual's right to choose to smoke, we felt it was no longer right to devote any of our resources to support what is a proven source of ill health, serious disease and death.
"We are offering all staff who wish to quit smoking support, and will be glad to direct any family member to sources of support, too, if they want to give up smoking."
He added: "We know families can be placed in terrible emotional turmoil by what is happening to their child when he or she is with us, and we will continue to help them through what can be devastating times, as we always have done, with our full range of professional and dedicated support services.
"But we are no longer prepared to allow smoking on the premises."
