Vaping has slowed teen smoking decline in New Zealand, especially among Māori and Pacific youth, researchers say.
A new study published in The Lancet Regional Health – Western Pacific finds that vaping has slowed the decline in teen smoking in New Zealand, particularly among Māori, Pacific, and European adolescents, with smoking rates in 2024 higher than expected if pre-2010 trends had continued.
Analyzing nearly 600,000 students aged 14 to 15 from 2003 to 2024, researchers found that while smoking declined before 2010, the pace slowed significantly after vaping became widespread.
In 2024, 20 more Māori, 15 more Pacific, and 13 more European teens per 1,000 were smoking than projected.
Vaping rates were highest among Māori (29%), Pacific (19%), and European (11%) teens, with no evidence that vaping replaces smoking—suggesting it may act as a gateway.
The study highlights growing health inequities and calls for stronger regulations to protect youth.
