E-cigarette devices expose users to toxic metals, UTS study finds

Dr Bordin explains this is important because many people believe vaping carries less risk than conventional cigarettes. This perceived reduction in harm, along with misleading marketing campaigns, has contributed to the rapid uptake of e-cigarettes globally, particularly among younger demographics. In Australia, for example, e-cigarette use among young adults increased from 5.3% in 2019 to over 21% in 2023, with a similar rise in adolescents.

“Our findings challenge the assumption that e-cigarettes are safer and shows how critical it is to review current vaping regulations, which should be expanded to include device-derived emissions, not just e-liquid composition,” she said.

“Vaping can deliver toxic metals directly into the lungs, even after short-term use. This information is important for anyone considering vaping, especially young people, because these metal exposures are largely invisible and rarely discussed.

“Specifically, there is a need for standards and routine testing of metal and organometallic emissions from e-cigarettes, particularly from heating coils and internal components,” said Dr Bordin.

“The results also support updating risk assessment frameworks and public health guidance to incorporate metal exposure and bioaccumulation and improving consumer awareness around these previously unrecognised risks.”
