The popularity of disposable e-cigarettes or vapes has fallen ahead of a UK-wide ban on their sale on 1 June, a study has found.Researchers believe vape users are switching to refillable and rechargeable vapes in anticipation of the ban.The percentage of people aged 16-24 who mainly use disposable vapes has dropped by nearly half in the last year from 63% to 35%, according to University College London (UCL) research.Overall vaping use stalled between January 2024 and 2025 in all adults over 16, after several years of significant growth.The UK government ban on disposable and single-use vapes is aimed at stopping littering as, in most cases, the vapes cannot be recycled and often end up in landfill or pollute natural environments.
