Health risk assessment: E-cigarette liquids, acute toxicity hazards and health risks

Please note: As of 1 July 2025, the New Zealand Institute for Public Health and Forensic Science (PHF Science) is the new name for the Institute of Environmental Science and Research (ESR). Research and reports published prior to this date may reference the organisation’s former name.

Summary

The health effects considered in this report include poisonings from e-liquids, intrinsic toxicological properties of e-liquid components, and injuries from explosions or burns and not health effects from vaping itself in the course of the intended use of e-cigarettes. This report does not consider the chronic long term health risks from vaping and therefore does not discuss the overall health considerations of e-cigarettes as alternatives to tobacco smoking or as smoking cessation aids. The purpose of this report is to summarise the literature on e-cigarette liquid acute toxicity hazards and risks.
