Could treatment be suitable?
A specialist may assess you if:
- You have a diagnosed condition or an established clinical history.
- Standard treatments have not helped enough or were unsuitable.
- You are 18 or over and live in the UK.
- Your records allow a doctor to review previous care and current medicines.
Understanding the condition
What is Parkinson’s disease?
Parkinson’s disease is a condition in which parts of the brain become progressively damaged over many years, reducing the production of a chemical called dopamine.
This loss of brain cells leads to symptoms such as tremors, slow movement and stiff, inflexible muscles. Symptoms are usually mild at first and gradually become more noticeable over time.
Recognising the impact
Common parkinson’s disease symptoms
Parkinson’s affects people differently, and symptoms develop gradually.
- Tremor, often starting in a hand or arm
- Slowness of movement
- Stiff and inflexible muscles
- Problems with balance and posture
- Disturbed sleep and fatigue
- Pain, anxiety or low mood
Conventional treatments
Conventional treatment options
Parkinson's is managed by specialists using medicines and therapies. Recognised options include:
- Levodopa combined with other medicines
- Dopamine agonists
- MAO-B inhibitors and COMT inhibitors
- Amantadine or apomorphine in selected cases
- Anticholinergics for specific symptoms where appropriate
- Physiotherapy, occupational therapy and speech and language therapy
Although these options help many people, they are not enough for everyone. If parkinson’s disease symptoms still affect daily life, a specialist assessment can help you understand whether another route may be suitable.
Specialist-led care
Can medical cannabis help with Parkinson's-related symptoms?
Medical cannabis is not a treatment for Parkinson's disease or its progression. Where certain symptoms such as stiffness, discomfort or sleep persist, a specialist may review whether it could help as part of wider care.
THC and CBD interact with the body’s endocannabinoid system, which is involved in movement, pain, sleep and mood. This is why researchers continue to study whether cannabis-based medicines may help with some Parkinson’s symptoms, such as pain, anxiety and sleep disturbance.
Where Parkinson’s-related symptoms continue to affect daily life, a doctor on the GMC Specialist Register reviews your diagnosis and current medicines to consider whether a prescription may be appropriate as part of your wider care. Effects can vary, so specialist guidance is key.
Effects can vary from person to person, which is why a GMC-registered specialist reviews your symptoms, goals, medicines and records before deciding whether treatment may be appropriate.

Evidence
What does the evidence say?
Developing evidence (symptom support)
Evidence on cannabis and Parkinson's disease is still developing and relates to symptom support rather than changing the condition itself. Research into cannabinoids in Parkinson's looks at symptoms such as sleep, pain, stiffness or anxiety, which a specialist reviews case by case.
- Levodopa and other recognised Parkinson's medicines remain the foundation of care.
- Evidence is still developing; it does not treat disease progression.
- Any role focuses on specific symptoms, reviewed individually.

Safety
Possible side effects
Medical cannabis is prescribed under specialist supervision, and patient experience can vary. Your clinician will explain what to watch for and adjust your plan if needed.
- Decreased appetite or feeling sick
- Diarrhoea or weakness
- Dizziness or feeling very tired
- Behavioural or mood changes
They’ll usually ease on their own, but speak to your clinician if they don’t improve over time.
