Health minister Norman Lamb, who revealed he quit smoking last week, said the cost of the campaign was about "a couple of million" pounds.
He told BBC Breakfast:
It costs the NHS over £2.7 billion a year, over 1,200 people admitted to hospital every day as a result of smoking, so this is an enormous killer.
With the number of lives that are lost, and the number of families that are destroyed as a result of that, surely to commit a bit of resource to a campaign that could result in saving lives is worthwhile.
