The Australian Government has created a Quit Now program (http://quitnow.gov.au/) to encourage folks to quit smoking complete with a worthwhile slogan: “Every cigarette you don’t smoke is doing you good.”
The program has embraced hypnotherapy as a means of helping folks give up smoking and their success stories are wonderful.
See http://www.thesatellite.com.au/story/2012/03/12/giving-up-ciggies-through-the-power-of-suggestion/ for the story.
