The thousands of available eliquids contain various excipients, nicotine, flavourings, and other additives. There is little to no regulation of their manufacture, and potentially dangerous ingredients and incorrect nicotine levels have been identified.2 Of particular concern is the frequency with which nicotine is detected in eliquids labelled “nicotinefree”.2 Eliquids containing nicotine cannot legally be sold in Australia,3 but inaccurate labelling means that users may unwittingly inhale this addictive substance, or retailers may sell incorrectly labelled nicotinecontaining eliquids to willing customers. The aim of our investigation was to assess the chemical composition of a range of eliquids available in Australia, focusing on nicotine and other potentially harmful compounds. Formal ethics approval was not required for this study.
