Hub page

Conditions and symptoms hub

Evidence-led UK guidance for patients exploring medical cannabis questions around pain, sleep, Crohn's disease, MS, autism, PTSD, anxiety, and mental health.

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.
