      Recreational drug use: stimulants

      Lesson details

      Learning outcome

      I can explain how stimulants affect the body in both the short and long term.

      Key learning points

      1. Stimulants make you feel more alert and can give you quicker thinking and reaction times.
      2. Caffeine is a legal stimulant present in some foods and drinks.
      3. Cocaine and ecstasy are examples of illegal stimulants used as recreational drugs.
      4. Substance abuse can cause physical and mental health issues.

      Keywords

      • Drug - a medicine or other substance that has a physiological effect when introduced into the body

      • Recreational - something that is done for fun

      • Stimulant - speeds up the messages sent from the brain the nerves

      • Legal - allowed by the law

      • Illegal - not allowed by the law

      Common misconception

      Legal drugs cannot lead to addiction.

      Nearly all drugs used for recreation, legal or illegal, can lead to addiction.

      Teacher tip

      Talk about the serious effects heroin can have on a person's life. They are likely to lose their job, friends and family. Many other types of opioids are just as addictive and devastating. Talk about Leah Betts who died in 1995 from drinking 7 litres of water in 90 mins after taking ecstasy.
