Over 200,000 Australians have either taken up the habit or switched from traditional cigarettes, but the effect e-cigarettes have on people's health and lung function still remains a mystery to researchers. A team of researchers at the University of Southern Queensland are hoping a new study, led by researcher Dean Mills, will provide answers around how the practice known as "vaping" affects lung health. Dr Mills said given e-cigarettes were relatively new devices, very little research had been done on their effects.
