Liverpool could soon follow in the footsteps of New York and Dublin as the next smoke-free city.
Campaigners are looking at using health and safety laws
The plans would make Liverpool the first city in Britain to ban smoking in public places.
City officials are considering making the controversial move in time for the Capital of Culture celebrations in 2008.
Smoke Free Liverpool - which includes representatives from the city council, health agencies and business leaders - has been set up to campaign for the changes.
The group is investigating health and safety laws which ban smoking in all public places including offices, shops, bars and restaurants.
A spokesman for Smoke Free Liverpool said: "The council is yet to sit down and debate the issue so no definite decision has been made yet. It is definitely something they are looking at though."
Research conducted for the council showed that annually there were 900 smoking related deaths in Liverpool.
The council is due to make a decision on the smoking ban by the beginning of next month.
