📘 Module 19 (C3): Caffeine Use & Cannabis Use Disorders

 


This module looks at two substance-related conditions that are often discussed together because they both involve dependence, withdrawal, and behavioural patterns of use, but they are treated very differently in diagnosis.


🧠 Overview

The DSM-5 distinguishes between:

  • A condition requiring further study (caffeine-related)
  • A fully recognised substance use disorder (cannabis-related)

👉 Both can affect health and daily life, but they are classified differently in clinical diagnosis.


☕ 1. Caffeine Use Disorder

Caffeine use disorder is currently listed in DSM-5 as a condition for further study, not a fully official diagnosis.


🔍 Key Features

People may show:

  • Strong desire or reliance on caffeine
  • Difficulty reducing intake
  • Continued use despite negative effects
  • Withdrawal symptoms when stopping

⚠️ Withdrawal Symptoms

When reducing caffeine, people may experience:

  • Headaches
  • Fatigue
  • Irritability
  • Difficulty concentrating

🧠 Important Note

  • It is not yet a full DSM-5 Substance Use Disorder
  • It is still being researched for diagnostic clarity

🌿 2. Cannabis Use Disorder

Cannabis use disorder is a fully recognised Substance Use Disorder (SUD) in DSM-5.


🔍 Key Features

A diagnosis requires 2 or more of 11 criteria, including:

  • Craving cannabis
  • Tolerance (needing more over time)
  • Withdrawal symptoms
  • Using more than intended
  • Difficulty controlling use
  • Impact on school, work, or relationships

⚖️ Severity Levels

  • 🟡 Mild: 2–3 symptoms
  • 🟠 Moderate: 4–5 symptoms
  • 🔴 Severe: 6+ symptoms

🔄 Comparison: Caffeine vs Cannabis

FeatureCaffeine Use DisorderCannabis Use Disorder
DSM-5 statusUnder studyFully recognised
ClassificationNot formal SUDSubstance Use Disorder
WithdrawalYes (mild symptoms)Yes (more significant symptoms)
SeverityGenerally lower riskCan range from mild to severe
Clinical urgencyLowerHigher

🧠 Shared Features

Both conditions can involve:

  • Tolerance (needing more over time)
  • Withdrawal symptoms
  • Difficulty cutting down
  • Psychological reliance

⚠️ Key Differences

  • Caffeine use is often socially accepted
  • Cannabis use disorder is a clinically diagnosed mental health condition
  • Cannabis has stronger links to:
    • impaired functioning
    • dependency
    • mental health impacts

🧩 Impact on Daily Life

Both can affect:

  • Sleep patterns
  • Concentration
  • Mood stability
  • Work or school performance
  • Motivation levels

💊 Support and Management

☕ Caffeine Use

  • Gradual reduction
  • Hydration and sleep support
  • Behavioural adjustment

🌿 Cannabis Use Disorder

  • Therapy (CBT and addiction counselling)
  • Structured support programs
  • Medical and psychological support
  • Relapse prevention planning

♿ Inclusion & Awareness Message

  • Substance-related conditions exist on a spectrum of severity
  • Legal or social acceptance does not equal safety or absence of harm
  • Early support improves outcomes for both conditions

📄 Easy Read Version

Caffeine Use

  • Some people rely too much on caffeine
  • It can cause headaches if stopped suddenly

Cannabis Use

  • Some people cannot control cannabis use
  • It can affect life, work, and health

Help

  • Doctors
  • Therapy
  • Support services

🧠 Reflection / Activity

Think about:

  • Why do people use caffeine or cannabis regularly?
  • When does use become a problem instead of a habit?

💬 Final Thought

This module shows that:

  • Not all substances are classified the same way
  • Some are still being researched
  • Others are fully recognised medical conditions

👉 Understanding helps reduce stigma and improve support.
