Adolescent and young adult (AYA) cancer survivors are vulnerable to future health complications and engage in risky health behaviors. Vaping or electronic cigarette use is increasing among AYA, yet little is known about the prevalence in AYA cancer survivors and associated morbidities. The objective of this research was to analyze the current state of the literature on vaping among AYA cancer survivors with scoping review methodology. Eligibility criteria included any vaping among people aged 13–39 years with cancer or a history of cancer. Database searches from PubMed, Web of Science, PsycINFO, and Scopus yielded eight cross‐sectional studies. Results suggest significant variability, with studies finding 2%–46% of AYA survivors have ever or currently vape. Medical (e.g., late effects), psychosocial (e.g., depression), and demographic correlates (e.g., younger age, male gender), as well as other risky health behaviors (e.g., cigarette smoking) were shown to be associated with vaping. Though the extant research is beginning the task of understanding comorbidities with vaping, few research has focused on those most vulnerable to vaping (survivors under age 18). More research is required to understand AYA survivors’ vaping behavior to better understand the significance and implications regarding the growing incidence of vaping among this vulnerable population.
