Electronic cigarette (e-cig) users are increasing worldwide. Little, however, is known about the health effects induced by inhaled e-cig aerosols. This article describes an e-cig aerosol generation technique suitable for animal exposures and subsequent toxicological studies. Such protocols are required to establish experimentally reproducible and standardized e-cig exposure systems.
