That is the theme for this year's World No Tobacco Day, which is being marked by health professionals and members of the community throughout western NSW on Saturday.

Cancer Council NSW has called on smokers to quit their habit and save money as new survey results show two-thirds of NSW adults would support increased tax on cigarettes.

"Smoking is the number one cause of preventable death in Australia and we know that increasing the price of cigarettes is the most effective way to reduce smoking rates," Cancer Council NSW western region community programs coordinator Camilla Barlow said.

A snapshot of tobacco use released by NSW Health earlier this month showed Western NSW had the state's highest rate of smoking amongst adults (22.6 per cent) compared with the state average of 16.4 per cent.

Western NSW Local Health District manager of health promotion Lyndal O'Leary said the region contained many areas of lower socio-economic status and a higher proportion of indigenous Australians, both factors that had a high correlation with smoking rates.

She said there were several programs operating in the region that aimed to prevent smoking, including stopping teenagers from starting.

"Our sales to minors program works with retailers to ensure staff check for ID when selling cigarettes," she said.

"We are also very much concerned with creating smoke-free environments, trying to sensure secondhand smoke does not impact upon non-smokers.

"We've been encouraging restaurants that are al fresco to go smoke free, and in Dubbo we've had about half of them do that."

Helping existing smokers to quit was also vital to boosting health and saving lives, Ms O'Leary said.

"Every time an individual goes to a hospital or has an appointment with a health service provider, they should be asked if they have considered quitting, and if they are interested they should be given Quit line information, and if you're in hopstial and you want to give up there is an opportunity to get medications to help do that."

In response to 2012 figures showing half of all Aboriginal mothers reported smoking during pregnancy compared with 9 per cent of non-Aboriginal mothers, the Quit for New Life program was being rolled out across the Western NSW LHD, enabling Aboriginal women and their families to work with Aboriginal health staff, during their pregnancies and for the three months after giving birth, to help them quit.

"The message there is think about your bub, you could end up with a bub that is smaller or has other health problems," Ms O'Leary said.
