Cannabis-Related Disorders: Types, Symptoms & Treatment

Cannabis-related disorders involve problematic use of cannabis (marijuana, THC, CBD) leading to significant impairment or distress. The DSM-5 identifies several cannabis-related conditions:

1. Cannabis Use Disorder (CUD)

DSM-5 Criteria (≥2 symptoms within 12 months)

  • Impaired Control: Using more/longer than intended.
  • Cravings: Strong urge to use cannabis.
  • Tolerance: Needing more to achieve the same effect.
  • Withdrawal: Irritability, insomnia, appetite loss when stopping.
  • Neglected Responsibilities: Work, school, or home life suffers.
  • Continued Use Despite Harm: Physical/mental health declines.

Severity Levels:

  • Mild (2–3 symptoms)
  • Moderate (4–5 symptoms)
  • Severe (6+ symptoms)

Risk Factors:

  • Early adolescent use, genetic predisposition, mental health disorders (anxiety, depression).

2. Cannabis Intoxication

Symptoms (Peak within 30 min–2 hrs):

  • Euphoria, relaxation, altered perception (time distortion).
  • Impaired coordination, red eyes, dry mouth (“cottonmouth”).
  • Adverse Reactions: Anxiety, paranoia, hallucinations (high-THC strains).

Complications:

  • Accidents (e.g., driving impairment).
  • Cannabis Hyperemesis Syndrome (CHS): Cyclic vomiting due to chronic use.

3. Cannabis Withdrawal

Symptoms (Begins 1–3 days after last use):

  • Irritability, anxiety, restlessness.
  • Sleep disturbances (insomnia, vivid dreams).
  • Decreased appetite, stomach pain.
  • Mild physical discomfort (headaches, sweating).

Duration: Typically lasts 1–2 weeks, but cravings may persist longer.

4. Cannabis-Induced Disorders

  • Psychotic Disorder: Paranoia, delusions, hallucinations (linked to high-THC use).
  • Anxiety Disorder: Panic attacks or worsened generalized anxiety.
  • Cognitive Impairment: Memory & attention deficits (“brain fog”).

Treatment Options

1. Behavioral Therapies

  • Cognitive Behavioral Therapy (CBT): Identify triggers & develop coping skills.
  • Motivational Interviewing (MI): Enhance motivation to quit/reduce use.
  • Contingency Management: Reward-based abstinence programs.

2. Medications (Limited Options, Under Research)

  • NSAIDs (e.g., ibuprofen) for withdrawal-related discomfort.
  • Sleep aids (melatonin, trazodone) for insomnia.
  • Anti-anxiety meds (short-term benzodiazepines) for severe withdrawal.

3. Harm Reduction Strategies

  • Switch to lower-THC/higher-CBD strains.
  • Gradual tapering instead of abrupt cessation.
  • Mindfulness & stress management to reduce cravings.

When to Seek Help

✔ Failed attempts to cut down.
✔ Withdrawal symptoms when stopping.
✔ Declining mental health (anxiety, psychosis).
✔ Cannabis Hyperemesis Syndrome (CHS) symptoms (vomiting, dehydration).

Emergency Signs:

  • Severe paranoia or psychotic symptoms.
  • Persistent vomiting (CHS) leading to dehydration.
