Changes in U.S. Adolescent Nicotine Vaping Prevalence From 2022 to 2023: The Role of Reduced Initiation Three Years Earlier During the Onset of the Pandemic.

INTRODUCTION

The prevalence of adolescent nicotine vaping declined substantially after the COVID-19 pandemic onset in the United States during the Spring of 2020. This study examines whether the decline continued from 2022 to 2023, and the extent to which any decline reflects the lasting influence of lowered levels of initiation 3 years earlier, at the onset of the pandemic.

AIMS AND METHODS

Data for this study come from nationally representative, cross-sectional surveys of U.S. 12th-grade (n = 9854) and 10th-grade (n = 14 663) students administered in the Spring of 2022 and 2023. The main outcomes are past 12-month nicotine vaping and grade first ever vaped nicotine.

RESULTS

From 2022 to 2023 prevalence of past 12-month nicotine vaping declined a relative 20% for 12th-grade students, from 24.3% to 19.1%, and for 10th-grade students by a relative 16%, from 17.8% to 15.1%. Among 12th-grade students who vaped nicotine in the past 12 months, a significant decline in prevalence took place only among those who first ever vaped nicotine in ninth grade, and not among those who first ever vaped nicotine in any other grade. Among 10th grade students who vaped nicotine in the past 12 months, a significant decline in prevalence took place only among those who first ever vaped nicotine in seventh grade, and not among those who first ever vaped nicotine in any other grade.

CONCLUSIONS

These results contribute national-level evidence that forestalled initiation of nicotine use for 1 year may have a lasting effect that continues to lower adolescents' levels of use many years afterward.

IMPLICATIONS

These findings caution against looking to contemporaneous policy for explanations of the large, 1-year decline in nicotine vaping from 2022 to 2023. It can be tempting to interpret the decline as a victory for current efforts to restrict adolescent access to vaping products, or current education/media campaigns that warn adolescents of the dangers of vaping. The findings of this study suggest, instead, that the 1-year vaping declines primarily result from declines in initiation that were set into place 3 years ago during the pandemic onset, more so than the immediate result of contemporaneous policy.
