|CSIRO have published a literature review on the use and health impacts of e-cigarettes and personal vaporisers.
Key findings include:
• The evidence available suggests that regular use of e-cigarettes is likely to have adverse health consequences.
• There is a lack of clarity about the magnitude of adverse health effects and quantity of e-cigarette use required to trigger adverse health effects.
• The evidence is consistent in suggesting that use of e-cigarettes by non-smoking youth predicts future smoking.
• While many smokers and former smokers state a preference for e-cigarettes as a smoking cessation method, the effectiveness of this method compared with other smoking cessation methods is not known.
• Based on the current evidence it is not possible to determine whether e-cigarettes have a positive or a negative effect on health in countries where they are permitted.
• When e-cigarettes are used by smokers instead of conventional cigarettes there is evidence for improvement in individual health, probably mainly due to the reduction in smoking.
• However, ‘dual use’ (using both e-cigarettes and conventional cigarettes) is popular.
• On present evidence, it is not possible to determine whether less restrictive access to e-cigarettes would reduce rates of smoking in Australia.
