Slide Deck
Drugs Unmasked
Learning Objectives:
• Define common drug categories
• Identify short- and long-term effects of each
• Practice strategies to resist peer pressure and make healthy choices
Welcome students and introduce yourself. Read the learning objectives aloud. Emphasize that by the end of this lesson, they’ll understand drug categories, recognize their effects, and learn how to make healthy choices under pressure.
What Are Drugs?
A drug is any substance (legal or illegal) that changes how our body or mind functions.
Common Categories:
• Stimulants
• Depressants
• Hallucinogens
• Opioids
Explain that 'drug' refers to any substance that affects how the body or mind works. Stress that understanding categories helps us recognize risks. Click to reveal each category.
Stimulants
Examples: Caffeine, Nicotine, Cocaine, Amphetamines
Short-Term Effects:
• Increased alertness & energy
• Faster heart rate & blood pressure
Long-Term Effects:
• Anxiety & insomnia
• Heart problems & addiction
Introduce stimulants. Ask: “Who drinks caffeine or energy drinks? How do you feel afterward?” Then explain short-term and long-term effects.
Depressants
Examples: Alcohol, Benzodiazepines, Barbiturates
Short-Term Effects:
• Relaxation & drowsiness
• Slowed breathing & impaired coordination
Long-Term Effects:
• Memory problems
• Dependence & liver damage
Define depressants and relate to alcohol examples. Prompt students to share experiences (e.g., feeling drowsy after drinking).
Hallucinogens
Examples: LSD, Psilocybin (mushrooms), PCP
Short-Term Effects:
• Hallucinations & altered perception
• Rapid mood swings
Long-Term Effects:
• Persistent psychosis
• Flashbacks & memory issues
Explain hallucinogens. Show brief images or describe visual distortions. Stress unpredictability of trips.
Opioids
Examples: Prescription painkillers (OxyContin), Heroin
Short-Term Effects:
• Pain relief & euphoria
• Slow breathing & drowsiness
Long-Term Effects:
• High addiction risk
• Overdose & organ damage
Define opioids by linking prescription painkillers to heroin. Highlight the current opioid crisis context.
Strategies to Resist Peer Pressure
• Be Assertive: Use a clear “No, thanks.”
• “I” Statements: “I’m not into that.”
• Offer Alternatives: “Let’s grab a snack instead.”
• Delay Tactic: “I’ll think about it.”
• Seek Support: Talk to a trusted adult
Discuss each refusal strategy. Invite volunteers to role-play saying “no” using an “I” statement or suggesting an alternative.
Scenario Discussion
Scenario:
Your friend offers you a pill at a party, saying it will make you feel amazing. You’re not sure what it is.
Discussion Questions:
- What would you say or do?
- Which refusal strategies fit best?
Read the scenario aloud. Give students 2 minutes to think, then 3 minutes for small-group discussion. Ask a couple of groups to share their ideas.
Next Steps & Quick Quiz
• Complete the Drug Effects Worksheet (match drugs to effects)
• Take the 5-question quiz to check understanding
• Reflect: Which strategy will you use if faced with pressure?
• Resources: Talk to school counselor or visit reliable websites
Explain that next they’ll complete the Drug Effects Worksheet and a short quiz. Remind them where to find additional support and encourage reflection.

Script
Drugs Unmasked Teacher Script
Introduction & Objectives (3 minutes)
“Good morning, everyone! Welcome to our session called ‘Drugs Unmasked.’ My name is [Your Name], and I’m glad you’re here today. Over the next 30 minutes, we’re going to:
• Define common drug categories
• Identify their short- and long-term effects
• Practice clear strategies to resist peer pressure and make healthy decisions
Please turn your attention to Slide 1 of the Drugs Unmasked Slide Deck. Let me read our learning objectives aloud, so we all know what to expect.”
(Click to reveal objectives.)
“By the end of today’s lesson, you’ll be able to talk confidently about different types of drugs, understand how they affect the body and mind, and use real refusal skills if you ever feel pressured.”
Drug Types & Effects Presentation (8 minutes)
Slide 2 – What Are Drugs?
“Let’s start with a basic question: What is a drug? A drug is any substance—legal or illegal—that changes how our body or mind works. (Click to reveal the list.)
We group drugs into four main categories: stimulants, depressants, hallucinogens, and opioids.
Why do you think it helps to organize drugs into categories?
Possible follow-up: “Great thoughts. Grouping helps us spot patterns in effects and risks.”
Slide 3 – Stimulants
“Now, let’s look at stimulants. These are drugs that speed up the body’s systems.
• Examples: Caffeine, nicotine, cocaine, amphetamines
• Short-Term Effects: Increased alertness and energy, faster heart rate and blood pressure
• Long-Term Effects: Anxiety, insomnia, heart problems, addiction
Quick question: Who here drinks coffee or energy drinks? How do you feel afterward?
Possible follow-up: “Notice the similarities between something as common as caffeine and more powerful stimulants. Overuse can lead to serious health problems.”
Slide 4 – Depressants
“Next up, depressants—they slow down the body’s systems.
• Examples: Alcohol, benzodiazepines, barbiturates
• Short-Term Effects: Relaxation, drowsiness, slowed breathing, impaired coordination
• Long-Term Effects: Memory problems, dependence, liver damage
Who has noticed feeling sleepy or less coordinated after an alcoholic drink or certain medications?
Possible follow-up: “Even prescription drugs can become dangerous if misused.”
Slide 5 – Hallucinogens
“Third category: hallucinogens. These cause visual or sensory distortions.
• Examples: LSD, psilocybin mushrooms, PCP
• Short-Term Effects: Hallucinations, altered perception, rapid mood swings
• Long-Term Effects: Persistent psychosis, flashbacks, memory issues
What images come to mind when you hear ‘hallucination’?
Possible follow-up: “Because trips are unpredictable, people can get into real danger without meaning to.”
Slide 6 – Opioids
“Finally, opioids—powerful pain relievers linked to high addiction risk.
• Examples: Prescription painkillers (OxyContin), heroin
• Short-Term Effects: Pain relief, euphoria, slowed breathing, drowsiness
• Long-Term Effects: Overdose, organ damage, severe dependence
Why do you think opioids are a major public health concern right now?
Possible follow-up: “The ease of access to prescription opioids has fueled the current crisis.”
Slide 7 – Strategies to Resist Peer Pressure
“Knowing how drugs work is half the battle. We also need solid refusal skills. On the slide, you’ll see five strategies:
- Be Assertive: A confident “No, thanks.”
- “I” Statements: “I’m not into that.”
- Offer Alternatives: “Let’s grab something else to do.”
- Delay Tactic: “I’ll think about it.”
- Seek Support: Talk to someone you trust.
Who wants to volunteer and role-play using an “I” statement or an alternative suggestion?
Possible follow-up: “Excellent! Notice how clear language and eye contact make refusal stronger.”
Drug Effects Worksheet (7 minutes)
“Great participation! Now I’m handing out the Drug Effects Worksheet. On this sheet, you’ll match each drug to its effects and answer two reflection questions.
Work on your own for about seven minutes. I’ll come around to answer any questions you have. Let’s begin.”
(After 7 minutes.)
“Time’s up! Please finish your last sentence and put your pencils down.”
Scenario-Based Activity (7 minutes)
“Next, let’s practice in pairs. Turn to someone sitting next to you and take one set of Scenario-Based Activity Cards. Each card describes a real-life situation. Read your scenario together, decide how you would respond, and choose which refusal strategy fits best.
You have five minutes. Let’s get started.”
(After 5 minutes.)
“Okay, let’s hear from two pairs. Who’d like to share your scenario and your response?”
Listen, then add: “Fantastic—notice how you used clear language and an alternative plan.”
Discussion & Quick Quiz (5 minutes)
“Now, we’ll come back together for a brief discussion. I’m projecting the Peer Pressure Discussion Guide.
Question: When might you need to use these refusal skills in real life? What challenges might come up?
After 1–2 minutes: “Thank you for sharing. Remember, it’s normal to feel nervous—practice makes it easier.”
“Finally, please take a copy of the Drugs Unmasked Quiz. You have five questions to answer in three minutes. When you finish, hand your quiz to me so I can grade it with the Drugs Unmasked Quiz Answer Key.”
(After 3 minutes.)
“Time’s up—please pass your quiz forward.”
Closure (1 minute)
“You all did fantastic work today. Remember:
• Drugs can affect your body and mind in very different ways.
• You now know clear, respectful ways to say no.
• If you ever feel pressured, reach out to a trusted friend, family member, or school counselor.
Thank you for your attention and participation. Have a great rest of your day!”
