The Dual Nature

  • Cannabis can have both beneficial and harmful effects on mental health
  • High-THC products in psychologically vulnerable individuals can trigger anxiety or psychosis
  • CBD has demonstrated anxiolytic and antipsychotic properties in clinical studies
  • Careful patient selection and monitoring is essential for mental health prescribing

Mental health is the area where the risks and benefits of medical cannabis are most finely balanced — making specialist assessment essential.

Evidence-Supported Benefits and Contraindications

  • Anxiety disorders: CBD has RCT evidence for social anxiety and PTSD-related anxiety
  • PTSD: THC reduces nightmare severity; CBD modulates fear extinction
  • Who should NOT receive high-THC cannabis: personal/family history of schizophrenia or psychosis, under-25s, current severe anxiety without prior THC experience
  • Start CBD-dominant in any patient with mental health history — slow titration, regular monitoring

UK cannabis clinics screen carefully for mental health contraindications. This is genuine clinical risk management, not bureaucracy.
