People often search for a simple list of conditions that medical cannabis can treat. The real picture is more cautious.

Key takeaways

  • A diagnosis alone does not make someone a good candidate.
  • Evidence is stronger for some conditions than for others.
  • Headline lists often blur formal guidance, specialist use, and anecdotal reports.
  • The better question is whether the treatment has a clear symptom target and a realistic safety plan.

Evidence base

NHS and NICE guidance remain narrow. They support cannabis-based medicinal products only in limited situations, and current reviews still show major gaps in the evidence base.

Patients commonly ask about chronic pain, MS spasticity, severe treatment-resistant epilepsy, intractable nausea and vomiting, PTSD, anxiety, and sleep problems. Some of those areas have more support than others, but none should be treated as a guaranteed result.

What patients should know

Use any "7 conditions" list as a conversation starter, not a promise. Ask whether the aim is symptom relief, fewer side effects from another medicine, or better day-to-day function. Those are different goals.

If a page claims cannabis helps every condition on the list, be cautious. That is usually a sign the evidence has been flattened into marketing.

When to speak to a clinician

  • You are considering paying for an assessment and want to know whether the condition is realistic.
  • You are not sure whether standard treatments have been tried first.
  • You have a mental health history, pregnancy concerns, or driving needs.
  • Symptoms are worsening and you need a clearer treatment plan.
