INTRODUCTION 

Opening Activity: “Helpful or Harmful?”

Show students different items and ask them to identify if they’re helpful or harmful:

  • Water: Helpful for drinking, harmful if you breathe it in
  • Medicine: Helpful when sick and used correctly, harmful when misused
  • Fire: Helpful for cooking, harmful if uncontrolled
  • Cleaning products: Helpful for cleaning, harmful if swallowed

Key Point: Many things can be helpful OR harmful depending on how they’re used.

Review Connection:

  • “Last week we learned about preventing drug abuse”
  • “Today we’ll learn about a bigger group of dangerous things called ‘harmful substances'”
  • “This knowledge will help you stay even safer”

 

PART A: UNDERSTANDING HARMFUL SUBSTANCES 

What Are Harmful Substances?

Simple Definition: Harmful substances are things that can hurt your body, mind, or both when they get inside you or touch you.

Key Characteristics:

  • Can damage your health
  • Can make you very sick
  • Can change how your brain works
  • Can cause addiction
  • Can be dangerous to touch or breathe

How Harmful Substances Enter the Body:

Four Ways Substances Can Hurt You:

  1. Swallowing (through mouth): Drinking or eating harmful things

Breathing (through nose/lungs): Inhaling dangerous fumes or smoke

Absorption (through skin): Harmful chemicals soaking through skin

Injection (through needles): Putting substances directly into blood

Demonstration: Use safe examples to show these pathways:

  • Drinking: Show proper vs. improper use of medicine
  • Breathing: Discuss good air vs. smoky air
  • Skin: Explain why we wash hands after touching cleaning products
  • Injection: Only doctors should use needles for medicine

Difference Between Harmful Substances and Drugs:

Similarities:

  • Both can damage health
  • Both can be addictive
  • Both can affect the brain
  • Both require safety precautions

Differences:

  • Harmful substances: Broader category including household items
  • Drugs: Usually refers specifically to medicines and illegal substances
  • Harmful substances: Include things not normally called “drugs”
  • Context matters: Same substance can be helpful or harmful depending on use

PART B: CATEGORIES OF HARMFUL SUBSTANCES

Examples:

  • Indian hemp (Marijuana/Igbo): Plant that people smoke

  • Destroy families and communities
  • Against the law

Category 2: Legal Substances Misused

Alcohol (Not for Children):

  • What it is: Drinks like beer, wine, spirits

Important Safety Rule: These products are safe when used properly for their intended purpose, but become deadly when inhaled to get high.

Category 5: Synthetic and Unknown Substances

What Are Synthetic Drugs: Man-made chemicals designed to copy the effects of other drugs but avoid laws.

Examples:

Why They’re Extra Dangerous:

  • Unpredictable effects: Can cause unexpected deadly reactions
  • No medical research: Don’t know what they do to the body

PART C: REASONS WHY PEOPLE TAKE HARMFUL SUBSTANCES (10 minutes)

Understanding Why (This Helps Prevention)

Reason 1: Curiosity

  • What it means: Wanting to know what something feels like
  • How it starts: “I wonder what this does…”
  • Why it’s dangerous: One time can cause addiction or death
  • Prevention: Learn facts before curiosity leads to experimentation

Reason 2: Peer Pressure

  • What it means: Friends or others pressuring you to try substances
  • Common phrases: “Everyone is doing it,” “Just try it once,” “Don’t be scared”
  • Why people give in: Want to fit in, fear of rejection
  • Prevention: Strong refusal skills and good friend choices

Reason 3: Problems and Stress

  • Family problems: Parents fighting, divorce, family member death
  • School problems: Bad grades, bullying, feeling left out
  • Personal problems: Low self-esteem, sadness, worry
  • Why substances seem attractive: Promise to make problems go away temporarily
  • Why this doesn’t work: Problems get worse, and substance use creates new problems

Reason 4: Escape from Reality

  • What it means: Using substances to avoid dealing with difficult situations
  • Examples: Using substances to forget about:
    1. Family stress
    2. School pressure
    3. Social rejection
    4. Physical or emotional pain
  • Why it backfires: Reality is still there when substances wear off, plus new problems

Reason 5: False Information

  • Lies people tell: “It’s natural so it’s safe,” “It’s not addictive,” “Everyone does it”
  • Media influence: Movies and music that make substance use look cool
  • Peer misinformation: Friends spreading wrong information
  • Prevention: Learning facts from trusted, reliable sources

Reason 6: Easy Access

  • At home: Finding parents’ medicine or alcohol
  • In community: Areas where substances are easily available
  • Through technology: Online sources or social media connections
  • Prevention: Adults securing dangerous substances, community safety efforts

Reason 7: Self-Medication

  • What it means: Using substances to treat physical or emotional problems without medical help
  • Examples:
    1. Using alcohol for sadness
    2. Using stimulants for tiredness
    3. Using pain medicine for emotional hurt
  • Why it’s dangerous: Wrong treatment can make problems worse
  • Better solution: Getting proper medical or counseling help

Age-Appropriate Understanding for Children:

What Primary 2 Students Should Know:

  • People make bad choices sometimes when they have problems
  • Having problems doesn’t make substance use okay
  • There are better ways to deal with problems
  • Trusted adults can help with any problem
  • Prevention is always better than trying to quit later

How to Help Others:

  • Be a good friend: Support friends who make healthy choices
  • Tell trusted adults: If you see someone using harmful substances
  • Don’t judge: People with substance problems need help, not criticism
  • Set good examples: Show others that you can have fun without substances

 

CLASS ACTIVITIES

Activity 1: “Substance Safety Detective” 

Show pictures of different substances and have students identify:

  • Is it helpful or harmful? (Many can be both)
  • When is it safe to use? (By adults, for intended purpose, following safety rules)
  • When does it become dangerous? (Wrong use, wrong person, wrong amount)

Examples:

  • Medicine: Helpful when prescribed, harmful when misused
  • Cleaning products: Helpful for cleaning, harmful if swallowed
  • Gasoline: Helpful for cars, harmful if inhaled

Activity 2: “Reasons and Better Solutions” (6 minutes)

Present problems and discuss healthy vs. harmful solutions:

Problem: “Feeling sad about family problems”

  • Harmful solution: Using substances to forget
  • Better solutions: Talk to trusted adults, do enjoyable activities, help others

Problem: “Friends pressuring you to try something dangerous”

  • Harmful solution: Give in to pressure
  • Better solutions: Say no, find different friends, tell adults

Problem: “Feeling left out at school”

  • Harmful solution: Try substances to fit in with different group
  • Better solutions: Join positive activities, be kind to others, talk to family

Activity 3: “Safety Rules Chant”

Teach students this safety chant: 🎵 “If you don’t know what it is, don’t touch it! If it smells strange or strong, stay away! If someone offers unknown things, say NO! Tell a trusted adult right away!” 🎵
