For UK medical-cannabis patients
Stop wasting your medicine
Heat-not-burn delivers your prescription without combustion, tar, or waste.
For UK medical-cannabis patients, the cleanest way to vaporise cannabis instead of smoking it is heat-not-burn. Combustion destroys up to 70% of the cannabinoids in flower before they reach your lungs. Omura's heat-not-burn vaporiser is lab-tested to extract over 99% of active compounds in the flower (SC Labs California) — the same prescription, ten times the value.
The science
99% extraction, 0% combustion
Omura uses precision convection: heated air passes through the Flowerstick at temperatures below combustion. Cannabinoids and terpenes vaporise; the flower never burns. Lab tests confirm over 99% extraction per session. You get the medicine your doctor prescribed — without the smoke, tar, or wasted dose.
- No tar.No carbon monoxide.
- No combustion byproducts.Just your prescription.

Common questions
Omura is the medical-cannabis device prescribed by Releaf clinicians. Built for repeatable dosing, designed for discretion.
Combustion burns flower at 600°C+, destroying cannabinoids and producing tar, carbon monoxide and carcinogens. Heat-not-burn warms the flower to 180–220°C — releasing vapour with the active compounds intact, no smoke.
Yes. Omura is the device Releaf prescribes for medical-cannabis patients. Use pre-filled Flowersticks or fill your own with the Home Fill System.

Prescribed for medical cannabis?
Releaf clinicians prescribe Omura because the device delivers the medicine, not the smoke. If you're prescribed medical cannabis in the UK, you can switch from combustion to vaporisation at your next consultation.
