Exposures to e‐cigarettes and their refills: calls to Australian Poisons Information Centres, 2009–2016

The popularity of e‐cigarettes has increased in Australia since they first became available as smoking cessation tools; an estimated 1.3% of the New South Wales population used them in 2015, and as many as 8.4% had experimented with them.1 E‐cigarettes have been recommended by Public Health England and the Royal College of Physicians as safe smoking cessation tools.2, 3 In Australia, a prescription is required for legally importing nicotine‐containing e‐cigarettes.4 The safety of these products for users and the risks for members of their households have not been established. Imported products may not conform to Australian standards, including having child‐resistant closures and appropriate labelling, and refill bottles containing highly concentrated nicotine solutions — one millilitre of which can be lethal if ingested by a child — can be purchased online. We undertook a retrospective analysis of calls to Australian Poisons Information Centres (PICs) during 2009–2016. PICs play a valuable role as health care sentinels when new products such as e‐cigarettes are introduced. Our study was exempted from formal ethics approval by the Children's Health Queensland Hospital and Health Service Human Research Ethics Committee.
