Friends (64.4%) and social media (46.7%) were the most common sources of information. Notable significant associations between information sources and modifications were: 1. nonsocial media Web sites and vape shops with rewicking and recharging disposable devices and modifying nicotine e-liquid; 2. nonsocial media Web sites with refilling rechargeable cartridges\/pods and disposable pods; and 3. social media with recharging disposable devices and mixing nicotine and cannabis liquids. Perceptions of reduced harm and \u201ccoolness\u201d were associated with various modifications.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>DISCUSSION<\/jats:title>\n                  <jats:p>AYAs are aware of and modify ENDS for purposes unintended by manufacturers.
