Cancer Council Tasmania is an organisation that provides information supported by evidence. It was disappointing to read Senator Eric Abetz's view that it makes good sense to wean smokers onto vaping (The Examiner, February 25). There is no evidence to support his claims. The short and long-term health effects of e-cigarettes are currently being researched. It took many years for the harms of tobacco smoking to be understood, so why are we rushing in to support the legalisation of vaping when there is insufficient evidence on understanding the impacts and harms, or not, of vaping.
