Trajectories of lifetime vaping in teens and young adults: latent transition analyses over one year.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDespite the bidirectional relationship between initiation of cannabis and nicotine vaping, little is known about the patterns of vaping experimentation and progression among young people. The goal of this study was to describe the progression of vaping over one year in a longitudinal sample of teens and young adults.
methods432 Vermont teens and young adults (ages 12–25) completed four items on lifetime occasions of vaping nicotine, cannabis, just flavoring, and cannabidiol at three timepoints between 2020 and 2021. Latent transition models with these items identified a multi-class solution across the timepoints. Poisson regression analyses identified baseline predictors of transitioning between classes over one year, including sociodemographics, substance use, and vaping harm perceptions.
resultsThree lifetime vaping classes emerged at baseline: Never (46.8%), Experimenting (38.9%), and Experienced (14.4%). A greater proportion of the Experienced class vaped nicotine on 20 + occasions (53.1%) compared with the Experimenting class (20.9%), and 100% vaped cannabis on 20 + occasions (vs. 0% in the Experimenting class). Over one year, 5% of the Never vaping class moved to the Experimenting class; predictors of this transition were past 30-day tobacco and alcohol use and low relative harm perceptions of vaping nicotine vs. vaping cannabis. The Experienced vaping class grew by 9%, associated with baseline past 30-day cannabis use.
conclusionsMore than 10% of young people transitioned into higher vaping class in one year. Past 30-day tobacco, alcohol, and cannabis use at baseline predicted transitions. Findings suggest the importance of comprehensive polysubstance prevention efforts to reduce vaping in young people.
