Introduction: Young adults (YA) are attempting to quit vaping, with many accessing smoking cessation programs with a lack of reported efficacy, highlighting the need for targeted vaping cessation support. Young people report seeing health professionals (HPs) as potential sources of support in the quitting process. Additionally, the current changing regulatory landscape around vaping in Australia potentially increases the number of those seeking health professional help for cessation. However, limited research exists on HPs' views and preparedness to assist YA with their vaping cessation; thus, this exploratory study aimed to gain insights into their readiness to support YA in quitting vaping. Aims and Methods: Data were gathered via eight co-design workshops (two groups each of two hours duration and six semi-structured interviews of 1-hour duration), facilitated online with 12 HPs. Data underwent thematic analysis. Results: HPs expressed a need for more information in supporting YA to quit vaping, with them presently relying on informal pathways of support and information for their practice. Participants reported a lack of evidence-based guidelines and a reluctance to prescribe nicotine vapes, expressing conflict with the changing regulatory landscape in Australia. Conclusions: Our findings identify a significant gap in health professional preparedness in supporting vaping cessation. HPs are working within a rapidly evolving regulatory environment and are feeling unprepared to address the widely spread issue of vaping, especially among young people. We demonstrate the critical need for guidelines and training of HPs to enable them to better support young people in quitting vaping. Implications: This qualitative study offers unique insights into the views and readiness of Australian HPs to support young people to quit vaping, specifically in the context of recent regulatory reforms. The results highlight the need for evidence-based guidance and training for HPs to inform their vaping cessation support practice.
