E-cigarettes are advertised as a safe way to help people quit smoking tobacco cigarettes, often on the basis that there are less chemicals than in tobacco smoke. In Australia, it is illegal to sell E-liquids that contain nicotine, so Dr Weens work focuses mainly on the different flavoured E-liquids you can buy and what effects these flavouring chemicals may have on cells in the lung independent of nicotine effects and how this may differ from cigarette smoke. But the story is more complicated than just what flavour you use. There are hundreds of different E-cigarette devices on the market including “Mod” E-cigarettes which let you alter the settings on the device to best suit the users particular tastes. One such modifiable setting is temperature, and so Dr Ween is also studying how the temperature used in the device may affect the potential risks of the inhaled vapour. The end goal of the work is to help define what risks may be present from flavouring chemicals and to compare them to tobacco smoke.
