Add transparency to your cannabis experience with CannaBias.
Create your anonymous account
Choose an anonymous username and confirm your email for secure access so you can participate in the community without sharing your personal details.
Browse and contribute

Verify your prescription and unlock full access
To access full product names and detailed info, verify your patient status at your clinic or with one of our ambassadors. Once verified, you'll unlock complete batch details and all platform features.
Why Verification Matters
Verifying your UK medical cannabis prescription unlocks access to the full product catalogue, detailed batch-level comparisons, and complete patient experience data. Non-verified visitors can browse clinic information and public content, but detailed CBPM product names are restricted to comply with UK prescription-only medicine rules.
Working with patient-led organisations that share our commitment to transparent, evidence-led medical cannabis care in the UK.
Together with United Patients Alliance and PatientsCann UK, we strengthen the patient voice, support informed treatment decisions, and move towards safer, more consistent access to medical cannabis for every eligible patient.
