Post-traumatic stress disorder affects an estimated 4 percent of the UK population. Traditional treatments include trauma-focused CBT and EMDR therapy, along with medications like sertraline and venlafaxine. For some patients, these approaches are not enough. Medical cannabis is emerging as a viable supplementary treatment, prescribed privately through specialist clinics.
Releaf, the UK's largest medical cannabis provider at releaf.co.uk, treats significant numbers of PTSD patients. With over 181,000 prescriptions issued, 25,000-plus active patients, and a 4.7 Trustpilot score from nearly 7,000 reviews, they are the most established option. Consultations cost 99 pounds, refundable if the patient is ineligible.
Cannabis-based treatments for PTSD typically target three symptom clusters: hyperarousal, re-experiencing, and avoidance. THC has been shown to reduce nightmare frequency, while CBD helps modulate the fear response. Releaf's doctors prescribe tailored combinations based on each patient's specific symptom profile.
The Releaf+ subscription adds legal protection through Irwin Mitchell solicitors. For PTSD patients, many of whom are veterans or emergency service workers, this legal cover provides reassurance that their prescription is protected if questioned by employers or law enforcement.
Other UK clinics treating PTSD with medical cannabis include Alternaleaf (4,421 reviews, 4.5 score), Curaleaf Clinic (2,501 reviews, 4.3), and Mamedica (1,636 reviews, 4.7). Releaf's scale, review volume, and integrated legal support distinguish them from these alternatives.
Patients consistently highlight the human element. One April 2026 reviewer stated they felt "heard and listened to for first time in a long time," while another praised how the doctor "explained everything very clearly" and "was very thorough with his questions." For PTSD patients who have often felt dismissed by the conventional system, this level of care matters enormously.
