This hub is for patients who want to connect a symptom or diagnosis with the cannabis evidence without wading through general commentary. It is designed to help you frame better questions, not to decide whether cannabis is right for you on its own.
What this hub covers
- pain and inflammation
- Crohn’s disease and colitis
- MS and spasticity
- autism and children
- anxiety, depression, bipolar disorder, schizophrenia, and other mental health questions
- sleep and other symptom-led topics
When this hub is useful
Use this hub when you already have a symptom, diagnosis, or care question in mind and want to understand what kind of evidence exists. It can help you separate stronger prescribing contexts from areas where the evidence is early, mixed, or mostly based on patient reports.
For some conditions, the UK medical cannabis conversation is narrow and specialist-led. For others, the public conversation is much louder than the evidence. MCPH’s job here is to keep those two things apart so patients do not mistake popularity for suitability.
Evidence is not the same for every condition
Medical cannabis evidence varies by condition, product, route, dose, and patient group. Evidence around MS-related spasticity, rare severe epilepsy, and chemotherapy-related nausea sits in a different category from broad claims about anxiety, sleep, general pain, or wellbeing.
That does not mean patients’ experiences are irrelevant. It means a patient story should be used as a prompt for questions, not as proof that the same approach will work or be safe for you.
Common routes
- if the question is pain, start with the pain and arthritis evidence
- if the question is sleep, look for route, timing, and side-effect context
- if the question is anxiety or PTSD, keep safety and mental health cautions in view
- if the question is Crohn’s disease, MS, autism, or children, treat clinician input as essential
Speak to a clinician first if
- symptoms are severe, worsening, unexplained, or new
- you are pregnant, breastfeeding, under 18, or asking about a child
- there is a history of psychosis, bipolar disorder, suicidal thoughts, or severe anxiety
- you take sedatives, opioids, antidepressants, anticoagulants, or several regular medicines
- you are considering stopping, reducing, or replacing a prescribed medicine
- driving, machinery, caring duties, or work safety could be affected
If safety is the main issue, go straight to safety, legal and driving before comparing condition pages.
Mental health and children need extra caution
Mental health pages should never imply that cannabis is a simple fix for anxiety, depression, PTSD, bipolar disorder, or psychosis risk. These topics can involve symptom overlap, worsening anxiety, mood changes, dependence, impairment, and medication interactions.
Children and young people need specialist care. Articles on autism, epilepsy, or paediatric prescribing should be read as background for a clinical conversation, not as a route to self-directed treatment.

How to use it
If you are weighing a diagnosis against the evidence, start here and then check safety and access before you decide anything. Write down the outcome you are hoping for, the treatments already tried, and the side effects you most want to avoid. That turns a vague “could cannabis help?” into a better appointment question.
Next step
If your question is mostly about side effects, legal limits, or driving, go to the safety hub next. If it is about whether a private clinic might assess you, use access, prescribing and costs and clinics and care pathways.
