      Lesson details

      Learning outcome

      I can describe what stimulants are, explain why people might use them, identify the risks involved and know how to help if someone has taken them.

      Key learning points

      1. A stimulant is a drug which speeds up the central nervous system to increase neural activity in the brain.
      2. Stimulants raise blood pressure, heart rate and respiration, and reduce sleepiness and the desire to eat.
      3. There are legal stimulants, such as caffeine and nicotine.
      4. Illegal stimulants include amphetamines, cocaine and ecstasy.
      5. Taking illegal stimulants can have serious physical, psychological and legal consequences.

      Keywords

      • Stimulant - a substance that speeds up the brain and body’s functions, increasing alertness and activity levels

      • Nervous system - the body’s command system made up of the brain, spinal cord and nerves

      • Dependency - when a person's body or mind relies on a drug to feel or function normally

      Common misconception

      All stimulants are illegal.

      Not all stimulants are illegal. Caffeine, found in everyday drinks such as coffee and energy drinks, and nicotine, found in cigarettes and vapes, are both legal. However, even legal stimulants can be harmful if used incorrectly or in large amounts.

      Teacher tip

      The lesson includes organisations which can support people struggling with drug misuse. You may wish to add local charities and organisations specific to the context of your school or setting.
