      Lesson details

      Learning outcome

      I can describe depressants and their associated risks, including legal consequences.

      Key learning points

      1. A depressant is a drug that slows the central nervous system down to decrease the neural activity in the brain.
      2. Depressants lower blood pressure, heart rate and respiration.
      3. Illegal depressants include heroin, nitrous oxide and cannabis.
      4. The recovery position is useful for someone who might be unconscious.
      5. There are risks associated with depressants, including legal consequences.

      Keywords

      • Depressants - substances that slow down the brain and body's functions, reducing alertness and activity levels

      • Inhibition - a feeling that makes one self-conscious and unable to act in a relaxed and natural way

      • Recovery position - a safe way to lay an unconscious person on their side to keep their airway open

      Common misconception

      Depressants just slow people down.

      Depressants often affect someone's sense of inhibition first. They may do things that they wouldn't do otherwise.

      Teacher tip
