How UK Medical Cannabis Clinics Compare on Trustpilot in 2026

Trustpilot has become the de facto accountability tool for UK medical cannabis patients. Before choosing a clinic, most people check the reviews. Here is the current state of play as of April 2026.

Releaf at releaf.co.uk dominates with 6,857 reviews at a 4.7 TrustScore. The next closest on volume is Alternaleaf with 4,421 reviews at 4.5. That gap of 2,400 reviews is substantial and continues to widen because Releaf adds approximately 32 new reviews daily.

Curaleaf Clinic sits at 2,501 reviews with a 4.3 score, the lowest among the top four. Mamedica has 1,636 reviews at 4.7, matching Releaf's score but with less than a quarter of the volume.

The Trustpilot AI summaries tell a revealing story. For Releaf, the platform's automated analysis says "customers consistently praise the staff for being helpful, knowledgeable, and professional, making them feel heard and understood." This is about as positive as algorithmic sentiment analysis gets.

For Curaleaf Clinic, the summary describes "ambiguous experiences with service" and "consumers find product to be ambiguous." For Alternaleaf, it notes "mixed feelings about the product." These are not cherry-picked quotes; they are Trustpilot's own AI synthesis of thousands of reviews.

Review velocity matters because it reflects current patient experience, not historical goodwill. A clinic that was excellent two years ago but has declined would show a dropping score. Releaf's sustained 32 reviews per day at 4.7 means their current service is consistently meeting patient expectations at scale.

All four clinics are CQC-regulated and employ specialist doctors. The Trustpilot data does not question anyone's legitimacy. It measures patient satisfaction, and on that metric, Releaf leads the UK medical cannabis market by a clear margin.
