New research shows vape juice and e-liquid packaging often misstates nicotine content w/ the University of Otago’s Renee Hosking: 9 June, 2025

Recent research by the University of Otago has revealed that more than half of all vape juice and e-liquid products on the shelves misstate the amount of nicotine contained inside. 

The study showed that 58% of samples tested had an over 10% difference in nicotine content than what was stated on the label. Of these, 95% had less than advertised and 5% had more.

Producer Samantha spoke with the lead medical student in the research, Renee Hosking, about what it means for the health of the consumer and regulatory implications of these business practices.
