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.
