There are some positive anecdotal reports of therapeutic response to cannabis in Tourette’s syndrome, dystonia and tardive dyskinesia. The use in Tourette’s syndrome is currently being investigated in clinical studies. Many patients achieve a modest improvement, however some show a considerable response or even complete symptom control. In some MS patients, benefits on ataxia and reduction of tremor have been observed following the administration of THC. Despite occasional positive reports, no objective success has been found in parkinsonism or Huntington disease. However, cannabis products may prove useful in levodopa-induced dyskinesia in Parkinson disease without worsening the primary symptoms.
