Analyzing Respiratory Risks in Cannabis Use
The Microscopic View
In 2019, a mysterious lung illness began affecting healthy young people across North America. The culprit? Often, it wasn't the cannabis itself, but what was added to the oil.
Vitamin E Acetate
A thickening agent found in illicit vape cartridges. When inhaled, it acts like a "coating" on lung tissue, preventing oxygen exchange.

Normal alveoli vs. "Oil-coated" alveoli
Combustion vs. Vaporization
Combustion (Smoking)
Heats plant matter to 400°C+
Produces tar and carbon monoxide
Triggers chronic bronchitis symptoms
Vaporization (Vaping)
Heats oil or flower without burning
Concentrates high levels of THC
Risk of EVALI from additives/metals
What is EVALI?
E-cigarette or Vaping product use-Associated Lung Injury
A serious medical condition where the lungs become inflamed and damaged by chemicals found in vaping products. Symptoms mimic severe pneumonia.
Shortness of breath, cough, chest pain
Fever, chills, and weight loss
Often requires hospitalization and oxygen
Critical Factor
The majority of EVALI cases were linked to THC-containing products, specifically from informal sources (friends, online, street dealers).
Is One "Safer"?
While vaping avoids combustion, it introduces new risks: heavy metals (lead, nickel), unregulated chemical additives, and extremely high THC concentrations that can overwhelm the developing brain and lungs.

Lesson 1: Lung Health
TEACHER RESOURCE
Instructional Overview
This lesson addresses the physiological impact of cannabis consumption methods, specifically focusing on the respiratory system. Students will move beyond "smoking is bad" to understand the specific chemical and physical mechanisms of injury in both traditional combustion and modern vaporization.
Key Learning Objectives
Differentiate between combustion and vaporization mechanisms.
Identify the role of Vitamin E acetate and other additives in EVALI.
Analyze the impact of high-potency THC concentrates on lung tissue.

Discussion Framework
Q: Why do many teens believe vaping is a "healthier" alternative to smoking?
Expected points: Lack of "smoke" smell, marketing of "clean" vapor, discreet nature, flavoring masks chemical harshness.
Q: How does the "informal market" (street carts) increase physical risk?
Expected points: No testing for pesticides or heavy metals, use of Vitamin E acetate as a thickener, inconsistent THC concentrations.
Teacher Background: EVALI Mechanics
Vitamin E Acetate: When heated and inhaled, this oil-like substance interferes with the surfactant in the lungs. Surfactant is the thin layer of fluid that keeps alveoli (air sacs) open. When it is coated in Vitamin E acetate, the alveoli can collapse or become severely inflamed, leading to respiratory failure.
High Potency Risks: Modern "dabs" or vape oils can contain 80-90% THC, compared to 15-20% in traditional flower. This extreme concentration can cause "cannabinoid-induced acute lung injury" even without additives, as the lungs struggle to process high volumes of concentrated aerosol.
Extension
Have advanced students research the specific chemical transformation that happens to propylene glycol when heated to high temperatures (formaldehyde formation).
Support
Provide a labeled diagram of the respiratory system for students to color-code areas affected by combustion vs. vaporization.

The "Chicken or Egg" Debate
Does cannabis use cause anxiety and psychosis, or do people with these conditions use cannabis to cope?
Correlation
Two things happening at the same time.
Causation
One thing directly making the other happen.
THC and Psychosis
Psychosis involves a "break from reality," including hallucinations (hearing/seeing things) or delusions (false beliefs).
Genetic Predisposition
THC can "unlock" latent psychosis in people already at risk.
Early Onset
Heavy use in teens can cause psychosis symptoms to appear years earlier.
The Risk Factor
People who use high-potency cannabis daily are nearly 5 times more likely to have a first-episode of psychosis.
— The Lancet Psychiatry Study
The Anxiety Paradox
Low Dose vs. High Dose
While small amounts might feel relaxing to some, high-potency THC (modern weed) often triggers paranoia, panic attacks, and severe social anxiety.
Brain Rewiring
Chronic use can desensitize the brain's natural anxiety-relief systems.
Withdrawal Anxiety
Quitting can lead to a massive spike in anxiety symptoms.
The Adolescent Window
Your brain continues developing until age 25. Introducing high levels of THC during this period is like trying to build a house while someone is constantly changing the blueprints.
Prefrontal Cortex
Decision making and impulse control are hit first.
Amygdala
Emotional regulation and fear response are disrupted.

Lesson 2: Mental Health
Discussion Guide
Teaching the "Double Link"
This lesson is sensitive. Students may have personal or family experience with these issues. The goal is not to stigmatize use or mental illness, but to objectively examine how they interact. Focus on the Developing Brain as the central theme—this provides a biological anchor for the discussion.
Core Concept: Correlation vs. Causation
Example to use in class: Ice cream sales and drowning incidents both go up in the summer. Ice cream doesn't cause drowning; the heat (a third variable) causes both.
With Cannabis:
High THC can cause paranoia (Causation).
People with social anxiety use cannabis to feel more comfortable in groups (Correlation / Self-medication).
Both things reinforce each other over time.
Key Vocabulary
Psychosis
Loss of contact with reality; hallucinations and delusions.
Predisposition
Genetic or environmental factors that make someone more likely to develop a condition.
Pruning
The natural process in the teen brain where unused neural connections are removed.
Facilitation Prompts
Prompt 1: "Self-Medication"
"If someone uses cannabis to help with anxiety, but then feels even more anxious when the effect wears off, what cycle are they starting? How might this affect their ability to develop other coping skills?"
Prompt 2: "The Age Limit"
"Why is the risk to mental health so much higher for someone who starts using at age 14 versus someone who starts at age 25? (Refer to prefrontal cortex development)."
Case Study Guidance
When students complete the "Correlation Case Study Organizer," guide them to look for:
Signs of Causation
Acute panic after a high dose; immediate onset of hallucinations after smoking high-potency flower.
Signs of Correlation
History of depression prior to first use; using cannabis specifically to 'numb' negative emotions.
Teacher Note: Red Flags
If a student reports symptoms of psychosis (hearing voices, extreme paranoia) during this lesson, refer them immediately to the school counselor or psychological services. These can be medical emergencies.

Defining the Relationship
In health science, we often talk about Correlation (two things happen together) versus Causation (one thing makes the other happen). When it comes to cannabis and mental health, it’s often a mix of both.
Example: Correlation
"I feel depressed, so I smoke cannabis to feel better. It works for a few hours, then I feel depressed again."
Why is this correlation? Write your explanation...
Example: Causation
"I have no history of anxiety, but after using a high-THC dab, I had a massive panic attack and felt paranoid for two days."

Case Study: Patient A
"Leo is 16. He started using cannabis daily about six months ago. Lately, he’s been telling his friends that he thinks the school’s security cameras are tracking his specific movements for a secret government database. He’s stopped coming to school because he’s 'scared of the signals.' Leo’s uncle has a history of schizophrenia. Before he started using cannabis, Leo was an average student with no history of paranoia."

Decoding CUD Slides Decoding CUD
Understanding Cannabis Use Disorder
What is CUD?
Cannabis Use Disorder (CUD) is a clinical diagnosis given when someone's cannabis use leads to significant impairment or distress in their daily life.
Tolerance
Withdrawal
Loss of Control
The Diagnostic Checklist
Clinicians look for at least 2 of these in a 12-month period:
01
Using more than intended or for longer than intended.
02
Persistent desire or failed efforts to cut down/quit.
03
Spending a lot of time obtaining, using, or recovering.
04
Strong desire or urge to use (cravings).
05
Use results in failure to fulfill obligations at school/work.
06
Continued use despite social or interpersonal problems.
Biological Signs
Tolerance
Needing markedly more cannabis to achieve the same "high" or feeling a diminished effect with the same amount.
Withdrawal
Irritability, insomnia, decreased appetite, and restlessness that occur when stopping use.
The Cycle
"I use it because I'm stressed. I'm stressed because I'm failing classes. I'm failing classes because I'm using it."
Beyond the High
CUD isn't just about "smoking a lot." It's about when the substance takes the driver's seat of your life, making decisions for your health, your relationships, and your future.
Recognition is the first step toward recovery.
DSM-5 Criteria Teacher Guide DSM-5 Criteria Guide
Lesson 3: Defining CUD
Teacher Resource
Clinical Framework for Teens
Teaching addiction to 10th graders requires shifting from moral judgment to clinical observation. The DSM-5 criteria provide an objective "scorecard." Remind students that they are not doctors and cannot diagnose themselves or others, but they can recognize patterns that signal a need for professional help.
Key Concept: The Impairment Threshold
The defining feature of a "disorder" is impairment . Using cannabis might be a choice, but being unable to stop even when it causes school failure or loss of friendships is a symptom of CUD.
Severity Scoring
Mild: 2–3 symptomsModerate: 4–5 symptomsSevere: 6 or more symptoms
Withdrawal Profile
Cannabis withdrawal is often dismissed as "not real" by students. Facts for the classroom:
Onset
Typically begins 24-72 hours after cessation.
Symptoms
Anger, aggression, sleep difficulty, nightmares, weight loss.
Duration
Peak intensity around day 4; can last 2 weeks.

Common Misconceptions
MYTH:
"You can't get addicted to weed."
FACT:
About 1 in 6 people who start using as teens will develop dependency.
Questioning Techniques
"What is the difference between liking a drug and being dependent on it?"
"How might the social media 'vibe' around weed make it harder for a teen to admit they have a problem?"
"If you had to pick the single most dangerous symptom on the list, which would it be and why?"

The Scenario: Maya
Maya is a varsity soccer player and an honors student. Over the last year, she started using cannabis "just on weekends" with her older brother's friends. Six months later, Maya is missing her 6:00 AM soccer practices because she "can't wake up." Her grades in Chemistry and AP History have dropped from As to Ds.
Two months ago, Maya promised her mother she would quit so she could focus on the state tournament. However, Maya has been secretly using every night because when she tries to sleep without it, she gets cold sweats, feels incredibly angry at her teammates, and "just wants to scream." She now spends most of her lunch break behind the school gym looking for her brother's friends to see if they "have anything."
Evidence Log: List specific actions from Maya's story that match the DSM-5 criteria.
Example: "Maya is missing morning soccer practices" -> Failure to fulfill major role obligations.
Withdrawal Identification:
Identify at least three withdrawal symptoms Maya is experiencing.
Severity Assessment:
Based on the criteria met, is this Mild (2-3), Moderate (4-5), or Severe (6+)?
Self-Reflection Question:
Why do you think Maya hasn't been able to keep her promise to her mother? Consider the biological changes (tolerance/withdrawal) vs. the behavioral changes.
CHS Paradox Slides The Paradox
Understanding Cannabinoid Hyperemesis Syndrome (CHS)
The ER Mystery
Emergency rooms are seeing a spike in patients with severe, uncontrollable vomiting and abdominal pain.
The Clue
Patients often report that the only thing that stops the pain and nausea is taking a scalding hot shower.
Diagnosis: CHS
A condition that occurs in long-term, chronic cannabis users.
Why is it a Paradox?
Standard Effect
Cannabis is often used medically to treat nausea and vomiting (e.g., in cancer patients).
The CHS Effect
In chronic users, the body’s receptors become overloaded, causing cannabis to trigger severe vomiting instead.
The body basically starts "rejecting" the THC.
The Progression of CHS
1
Prodromal
Early signs: Morning nausea, abdominal discomfort, and fear of vomiting.
2
Hyperemetic
Crisis: Intense, persistent vomiting; abdominal pain; dehydration.
3
Recovery
Healing: Symptoms stop only after the person completely stops using cannabis.
The Hard Truth
Anti-nausea medications often fail to work for CHS. The only way to stop the syndrome and prevent it from coming back is:
Complete Cessation
If use resumes, the symptoms almost always return, often more severe than before.
CHS Medical Brief Teacher Guide CHS Medical Brief
Lesson 4: Cannabinoid Hyperemesis Syndrome
Teacher Resource
The Paradoxical Effect
This lesson is a "myth-buster." Many students view cannabis as a purely medicinal substance with no physical "overdose" or "rejection" symptoms. CHS is a growing medical reality that directly contradicts the popular narrative of cannabis as a harmless anti-nausea aid.
Key Learning Objectives
Explain the biological paradox of CHS (treatment vs. trigger).
Identify the three phases of the syndrome.
Analyze why hot water immersion provides temporary relief.
Recognize complete cessation as the only definitive cure.
The "Hot Shower" Fact
Why hot showers? High heat triggers the TRPV1 receptors in the skin, which cross-talk with the endocannabinoid system. This provides temporary relief for the intense abdominal pain and nausea, but it is a diagnostic red flag for doctors.
Teacher Background: Biological Mechanism
Receptor Downregulation: Chronic high-potency THC use leads to the "downregulation" of CB1 receptors in the hypothalamus and the digestive tract. Essentially, the receptors "hide" or stop working because they are overwhelmed.
The Digestive Disruption: While CB1 receptors in the brain can suppress nausea, those in the gut can slow down digestion (peristalsis). In CHS, the gut-slowing effect becomes dominant, leading to a toxic buildup and violent vomiting.
Classroom Discussion Prompts
Q: Why do patients often struggle for years before getting a CHS diagnosis?
Expected points: They use more cannabis to try and treat the nausea it's causing; they may hide their use from doctors; CHS mimics other stomach flu or food poisoning symptoms.
Q: How does the "hot shower" symptom help a doctor narrow down the diagnosis?
Expected points: It's unique to CHS; most stomach flu or other issues don't respond to external heat in this specific way.
Emergency Complications
CHS isn't just uncomfortable—it's dangerous. Remind students that severe vomiting leads to Electrolyte Imbalance and Kidney Failure . Many patients require IV fluids and hospitalization.

Read the symptom description below. Highlight or underline the two specific diagnostic clues that would lead a doctor to suspect CHS over a typical stomach virus.
"The patient presents with severe abdominal cramping and vomiting that has persisted for 48 hours. They report a 5-year history of daily cannabis use. They also mention that they have spent nearly four hours in a hot shower today because it is the only time the pain stops. Standard anti-nausea medication administered in the ambulance had zero effect."
