E-cigarette use has significantly escalated among young adults in recent years. The purpose of the current study was to better understand alternative ways in which young adults use their e-cigarettes in situations where ad-lib use is prohibited. The current study is a secondary analysis to a parent study assessing facilitators and barriers for tobacco use among young adult military personnel. Ten focus groups were conducted with 83 Airmen at the end of their Technical (advanced) Training. Focus group discussions were transcribed and thematic analysis was used to determine trends related to risky e-cigarette use. Participants described using liquids with extremely high nicotine contents or using the e-cigarette so quickly and intensely that they could not stand up or became ill. Results highlight the ease by which individuals can make alterations to their e-cigarettes or their use behaviors, which could potentially increase their risk of nicotine poisoning.
