Researchers say the Vape industry and regulators needs to show they're taking consumer safety seriously.
A study in today's Medical Journal shows more than half of vape juices have incorrectly labelled how much nicotine they contain.
Most of the mislabelled products had significantly less nicotine than advertised – some by over 50%.
Otago University Senior Research Fellow Jude Ball told Mike Hosking this is suggestive of widespread issues in manufacturing quality.
She says New Zealand has strong regulations about what can and can't be in vape products, so the fact nicotine levels are way off raises concerns.
