"Australia can catch up with Canada, New Zealand, the United States, and the United Kingdom and legalise smoke-free alternatives to help smokers quit for good".
"If you have a method of helping people with smoking cessation that is both more effective and less costly, that should be of great interest to anyone providing health services", said Kenneth Warner, a retired University of MI public health professor who was not involved in the study.
