Who this lesson is for?

This lesson is designed for secondary students who have some prior understanding of consent and respectful relationships, and who are ready to explore how substance use can affect decision-making in sexual situations. It suits students in Years 10 to 13 who are building on earlier learning about personal safety and respectful relationships.

It is suitable for:

  • senior secondary wellbeing or Health lessons

  • PDHPE units covering relationships and personal safety

  • pastoral care or advisory sessions

  • respectful relationships or consent education programmes

  • senior students with some prior understanding of consent and respectful relationships

Suitability should be based on more than age alone. Teachers should consider the lesson focus, student maturity, cohort needs, classroom culture, existing discussion norms and available support pathways.

Best used when

Use this lesson when students need clear, practical language for recognising unkind behaviour and knowing what to do next.

  • Introducing consent and substance use together Use when students need a structured way to connect consent education with decision-making around alcohol, drugs or vaping.

  • Building on earlier respectful relationships learning Use when extending previous consent or relationships lessons into more complex, real-world decision-making.

  • Supporting senior wellbeing or Health programmes Use when reinforcing personal safety and respectful relationships content within a wellbeing or Health sequence.

  • Preparing students for social situations Use when students are approaching situations, such as parties or social events, where substances and peer pressure may be present.

  • Strengthening help-seeking pathways Use when students need clearer understanding of who to approach for support around safety, consent or substance use.

  • Creating a structured, consent-led discussion Use when you want a calm, teacher-led discussion about substances, decision-making and respectful relationships.

The lesson can be used proactively with the whole class. It does not need to follow a specific incident.

Why this lesson matters

Senior students often navigate social situations where alcohol, drugs or vaping are present, and where decisions about consent and personal safety can become more complex. Understanding this connection early helps students build safer habits before they are faced with real situations. This lesson is not about warning students away from social situations. It focuses on building practical skills, such as recognising how substances can affect judgement, communicating boundaries clearly and knowing how to support a friend or ask for help. By keeping the discussion calm and skills-based, the lesson helps normalise conversations about consent and substance use, rather than treating them as topics to avoid.

Curriculum and framework alignment

Teaching notes & Delivery Considerations

This lesson includes content about unkind behaviour, exclusion and asking adults for help. It should be taught with calm, clear discussion norms.

Before teaching

  • Remind students not to name classmates or share personal stories

  • Frame discussion around scenarios and general examples, not personal disclosures

  • Make clear the lesson is about building safe decision-making skills, not judging choices

  • Identify trusted adults or support services students can approach at school

  • Be prepared to follow your school's child safety, wellbeing or child protection procedures if a student discloses harm or says they feel unsafe.

During delivery

  • Keep language age-appropriate, respectful and free from graphic detail

  • Focus on consent, safety and decision-making rather than specific substances

  • Allow students to respond through discussion or written reflection depending on confidence

  • Reinforce that students do not need to manage unsafe situations alone

Supporting safe discussion

  • Use general examples rather than personal experiences

  • Reinforce that seeking help is a responsible choice, not a failure

  • Direct students to school-based or external support pathways where relevant

Adaptation options

  • Use small group discussion for confident cohorts

  • Use written reflection or scenario cards for quieter groups

  • Spend more time on help-seeking pathways if students need support identifying who to approach

Keep the focus on decision-making, respect and safety rather than legal specifics or clinical detail, and refer students to appropriate support services where needed.
