Knowledge about the composition and physiological effects of e‐liquids is essential for assessing their effects on health

The popularity of electronic cigarettes (e‐cigarettes) has surged in the past few years, and it is estimated that 1.2% of Australians now use them.1 While the main premise in support of e‐cigarettes is that they are safer for smokers than conventional tobacco products, a considerable proportion of users are, unfortunately, never‐smokers or young people.2,3 In 2020, about 3.6 million young people in the United States reported current e‐cigarette use,2 and in 2017, 14% of secondary school students in Australia were reported to have ever used e‐cigarettes.3
