CBPM Patient Handbook
A practical starting point for patients using cannabis-based prescription medicines in the UK. This handbook brings together the Purus Articles on treatment routines, device care, safety, storage, travel, and informed self-management.
Important
This handbook is for education only. It is not a diagnosis, prescription, dosing instruction, or substitute for advice from your prescribing clinician or pharmacist. Do not change your medicine, dose, device settings, or treatment plan without speaking to your clinical team.
How to use this handbook
Start with the sections that match your immediate question, then use the linked articles for the full evidence, practical detail, and source material. Keep a written record of questions for your next clinical review.
1. Understand the treatment pathway
Your prescription, product, route of administration, treatment goals, and follow-up plan should be understood as one connected pathway. Ask your prescribing team what the medicine is intended to help with, how response will be reviewed, what unwanted effects to monitor, and who to contact when something changes.

2. Build a safe daily routine
A consistent routine helps you notice changes in response, unwanted effects, product condition, and device performance. Follow the instructions supplied with your medicine and device. Record what matters to your clinical review, including changes in symptoms, sleep, function, side effects, and any missed or delayed doses.

3. Look after the device
Device care is part of a reliable treatment routine. Residue, blocked pathways, worn components, and inconsistent cleaning can affect performance and the experience of use. Follow the device manufacturer's instructions and use suitable materials and processes for your device.

4. Understand your medicine and its context
Patients deserve clear information about product identity, quality, storage, interactions, and the limits of what is known. Take questions about other medicines, supplements, alcohol, driving, work, and travel to your prescriber or pharmacist.

5. Store and handle medicines carefully
Storage conditions can affect product quality and consistency. Follow the product instructions and keep medicines secure, clearly identified, and away from children and anyone who should not access them. Check with your clinical team or dispensing pharmacy if packaging, appearance, smell, or product condition changes unexpectedly.

6. Driving, work, travel, and everyday life
Plan ahead for travel and work. Carry the documentation your clinical team recommends, keep medicine in its original packaging where appropriate, and check the current rules for your destination before travelling. Do not drive or operate machinery if you feel impaired. For UK driving questions, read the relevant guidance and discuss your own circumstances with your prescriber.

7. Keep learning and ask better questions
Evidence develops over time. Be cautious of absolute claims, miracle language, and advice that ignores your prescription, medical history, or other medicines. The strongest patient position is informed, observant, and willing to ask for clarification.
