Lesson details

Key learning points

  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.
