      Lesson details

      Learning outcome

      I can describe what hallucinogens are, explain their risks and effects, and know how to respond if someone needs help.

      Key learning points

      1. Hallucinogens are drugs that change the way someone's senses perceive the world.
      2. Hallucinogens have risks, including legal, physical and psychological risks.
      3. Most hallucinogens are Class A drugs, with very serious consequences for possession and supply.
      4. There are different ways to say no to others.
      5. There are organisations and trusted adults who can offer help and support.

      Keywords

      • Hallucinogen - a type of substance that can change the way people see, hear, taste, smell, think or feel

      • Distort - to change or twist something away from its normal or true form

      • Hallucination - a false experience involving sight, sound, touch, taste and/or smell that seems real

      • Flashback - in this context, when someone re-experiences the effects of a hallucinogen after the effects have worn off

      Common misconception

      Psilocybin is safe because it is natural.

      Just because something is natural, it does not mean it is safe. Magic mushrooms carry serious risks, including paranoia and unpredictable psychological effects. Every person reacts differently, so there is no way to predict what will happen.

      Teacher tip

      Before teaching this lesson, you might speak to your school's DSL or RSHE lead about any hallucinogens which are known to be used in your local area.
