The basics
What medical cannabis flower is
Medical cannabis flower is the dried, cured flower of the cannabis plant, which is manufactured in line with strict pharmaceutical standards and regulations. It is a form of medical treatment prescribed to eligible patients in the UK as a whole flower to be administered via vaporisation.
It should never be smoked, as smoking medical cannabis remains strictly illegal under UK law, even with a valid, legal prescription.
Each batch of medical cannabis flower is tested and labelled with a unique cannabinoid profile that clinicians can tailor to each patient’s needs. This allows them to recommend certain cultivars and dosages based around factors that include a patient’s specific symptoms, medical history or lifestyle.
Since each cannabis cultivar contains a different balance of terpenes and cannabinoids, it is up to the clinician’s discretion to determine which specific form of medical cannabis flower is most suited to a patient’s needs.
How it's used
Taken by vaporisation, not smoked
Medical cannabis flower is heated to a specific temperature using a dry-herb vaporiser. This then releases the therapeutic cannabinoids and terpenes in the form of a vapour, which can be inhaled without burning the material.
Grind and load
After grinding your prescribed medical cannabis flower, place it into the chamber of a compatible dry-herb vaporiser, as directed by its packaging. Don’t overstuff it; only load the dosage required.

Set the temperature
Use the device to heat the flower to a specific, controlled temperature set by your clinician. This will create a vapour without burning it.

Gently inhale
Take a slow, gentle inward breath from the dry-herb vapouriser. Don’t draw too hard or smoke it in any way, as smoking (combustion) is not legally allowed for medical cannabis administration.

Clinician-led titration
Prescribing medical cannabis flower allows clinicians to monitor treatment over time. They can then make fine, gradual dosage adjustments where needed and administer cultivars with different cannabinoid profiles.
