E-cigarette access and age verification among adolescents, young adults, and adults.
Article in Addictive behaviors, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
backgroundAdolescents and young adults continue to access e-cigarettes despite regulatory efforts to prevent sales to those under 21. Prior research on sources of acquiring e-cigarettes excludes key online sources. This study aims to update evidence on where and how different age groups (adolescents, young adults, and adults) access e-cigarettes.
methodsA cross-sectional, online survey of 13-40 year-olds who used e-cigarettes in the past 30 days was conducted from November-December 2021. STUDY OUTCOMES: where past 30-day users obtained and bought e-cigarettes (retail stores; online, including e-cigarette company and multi-brand websites; social media; home delivery applications; and someone they know); and whether and how age was verified.
resultsIn our sample, 55.0% reported obtaining e-cigarettes from retail stores, 44.9% online, and 24.0% from someone they know (n = 2,256), although most 13-17-year-olds obtained their e-cigarettes from someone they know. Double the proportion of 21-40-year-olds (7.0%) and higher than 18-20-year-olds (9.8%), 13.4% of 13-17-year-olds obtained e-cigarettes through social media. Social media, Snapchat, Instagram, and TikTok were common platforms to buy e-cigarettes among those under 21; common sources on social media included friends their age, store/company accounts, and influencers. Approximately 20.0% of those under 21 bought e-cigarettes from internet vendors (including multi-brand websites) and 10.4-15.5% used home delivery applications. Across participants, 14.2% reported that their age was not verified, and 17.8% reported that their age was rarely verified.
conclusionsA sizeable proportion of adolescents and young adults under 21 years and adults above 21 acquired e-cigarettes from retail and online sources. Less than a quarter of those underage reported having their age verified all the time, warranting enforcement of existing age verification regulation and development of strategies to prevent underage access online.
