Introducing a special issue of rapid research on disposable e-cigarettes

Much has been written about e-cigarettes since they first started to become popular early in the 2010s. A PubMed search returns over 10 000 articles including the terms ‘e-cigarettes’ or ‘vaping’. Research has established that e-cigarettes are less harmful than cigarettes, effective for smoking cessation and were initially primarily used by people who had smoked cigarettes [1-4]. Since approximately 2021, new forms of disposable e-cigarettes rapidly became popular in many countries [5-12], including among never smokers, particularly adolescents and young adults [3-7]. These devices typically deliver nicotine more effectively than older types, are sold cheaply and are widely available (as opposed to only being sold in specialist vape shops).
