Quit4October logo.jpgYou can now get additional support to quit smoking by joining thousands of other Australians in the QUIT4october campaign.

QUIT4october is a month-long annual stop smoking event conducted through October, under the auspices of Lung Foundation Australia. Free registration is now open on the QUIT4october website. Why not encourage your smoking family and friends to sign up and support them through the quitting journey?

The most effective way to quit smoking is with the help and support of a health professional and medication to ease cravings and nicotine withdrawal. If you can stay smoke free for one month, you are at least 5 times more likely to become a permanent ex-smoker.

QUIT4october provides additional support such as

  • Online resources: videos, information, lung health check; a checklist to support your conversation with your GP or pharmacist
