      Lesson details

      Learning outcome

      I can explain the impact of drugs on decision-making and risky sexual behaviour.

      Key learning points

      1. Drugs impair cognitive functions, including decision-making and memory.
      2. Risky sexual behaviours are more likely when under the influence of drugs.
      3. Clear strategies can help avoid risky situations involving drugs and sex.

      Keywords

      • Drug - a substance that changes the way bodies and brains work

      • Consent - in this context, a voluntary agreement to engage in sexual activity which cannot be legally given when someone is heavily under the influence of drugs or alcohol

      • Decision-making - the process of making choices, which can be negatively affected by drugs or alcohol

      • Risky sexual behaviour - sexual activities which could lead to an increased chance of STIs, unintended pregnancy or feelings of regret

      • Inhibitions - the body’s way of regulating words and actions, which are reduced or removed under the influence of drugs or alcohol

      Common misconception

      Drugs and alcohol have no impact on consent.

      Drugs and alcohol can make it hard for people to give clear consent because they affect judgement and lower inhibitions.

      Teacher tip

      Consider discussing: Why might some people feel pressure to use substances in social or intimate situations? How can we challenge the myth that drugs or alcohol are needed to feel confident or have fun? What healthy alternatives exist for managing social anxiety or building genuine confidence?
