NHS Medical Cannabis Guide UK 2026 – Eligibility, Prescriptions & RSO Access
This page summarises official NHS guidance on medical cannabis in the UK (as of February 2026). For the most accurate and up-to-date information, always refer directly to: NHS.uk – Medical Cannabis.
Traditional RSO (high-THC Rick Simpson Oil) is not an NHS-approved product and is never routinely prescribed.
Most high-THC access occurs privately through specialist clinics (prices often start around £30+ per gram from licensed suppliers).

When Is Medical Cannabis Prescribed on the NHS? (2026)
NHS prescriptions are restricted to specific conditions where standard treatments have failed or are unsuitable:
- Severe treatment-resistant epilepsy (e.g. Epidyolex – pure CBD oral solution)
- Chemotherapy-induced nausea and vomiting (e.g. Nabilone – synthetic THC capsules)
- Moderate to severe MS-related muscle spasticity (e.g. Sativex – THC/CBD oromucosal spray)
High-THC products similar to RSO are not routinely funded by the NHS. Most access occurs privately.
