This practical professional development session equips HPE teachers with the skills and confidence to have more productive, meaningful conversations with teenagers about vaping and substance use. Moving beyond fear-based messaging, the session focuses on evidence-informed, student-centred communication strategies that build trust, reduce defensiveness, and encourage critical thinking. Participants will explore why young people use substances, how social and environmental factors influence decision-making, and what actually supports behaviour change. Through real-world scenarios and simple frameworks, teachers will learn how to respond to common questions, misconceptions, and resistance in a calm, non-judgemental way. The session emphasises brief, classroom-ready approaches that fit within HPE curricula and everyday interactions, helping educators create safe spaces where students feel heard and supported. Teachers will leave with practical conversation starters, questioning techniques, and strategies to guide discussions that are engaging, relevant, and impactful. Ideal for educators seeking to strengthen their preventive health education approach, this session reframes conversations about vaping and substance use as opportunities to build connection, capability, and informed choice.
