Proponents of vaping often argue it helps people quit tobacco, but a new study has found that while smoking rates among 14 to 15-year-olds have declined substantially in recent decades, the rise of e-cigarettes may have slowed that decline.
The study, published in The Lancet Regional Health—Western Pacific, found no evidence that vaping reduces harm for adolescents. Instead, it suggests vaping has “substantially added to harms,” particularly for Māori youth.
