Medical Cannabis for Tourette Syndrome in the UK

Limited but positive evidence from clinical trials

The short answer

A specialist doctor in the UK can consider prescribing medical cannabis for adults with severe tics that at least two standard medicines have not controlled, assessed by a neurologist or psychiatrist. Prescribing for under-18s is very rare. Whether it is suitable for you is the specialist's decision.

Overview

Tourette syndrome (TS) is a neurodevelopmental condition characterised by repetitive, involuntary movements and vocalisations called tics. It typically begins in childhood and severity often fluctuates. When tics are severe and disabling and have not responded to standard treatment, medical cannabis may be considered.

Common Symptoms

  • Motor tics — blinking, grimacing, head jerking, shoulder shrugging
  • Vocal tics — throat clearing, sniffing, repeating words or phrases
  • Tics that are temporarily suppressible but cause significant distress
  • Associated ADHD or OCD in many patients

Conventional Treatments

Typically tried before medical cannabis is considered

  • Habit Reversal Training (HRT)
  • Clonidine
  • Aripiprazole
  • Haloperidol
  • Risperidone

Eligibility Notes

Assessment is typically by a neurologist or psychiatrist with experience in Tourette syndrome. Evidence that at least two standard tic-suppressing medications have been tried without adequate response is expected. Prescribing in under-18s is very rare and would require specialist paediatric input.
