Victoria may be almost entirely smoke-free by 2025 under a plan backed by 25 of the state's most influential health groups.

Supported by the Australian Medical Association and the Cancer Council, the proposals aim to introduce stricter anti-smoking laws and more education programs.

Vic Health is leading the campaign to be launched on Thursday and aims to have less than five per cent of Victorians smoking daily by 2025.

The new proposals include discontinuing tobacco advertising and promotions and rolling out TV education campaigns for young people, News Corp Australia reports.

Other smoking-related laws would be tightened, including potentially banning smoking in outdoor drinking areas and reducing the number of outlets that sell cigarettes.

'We think it is actually possible to get down to five per cent daily smoking by 2025 -that would virtually eliminate daily smoking,' Quit Victoria director Dr Sarah White said.

'What we have seen from our politicians is tobacco control fatigue; we have had the lowest spending on anti-smoking campaigns.

'You can basically buy ­tobacco in more places than you can buy milk and bread. There are the equivalent of 44 tobacco retailers for every McDonald' s in Australia.'
