Abstract

The Tourette Association of America (TAA) understands and supports the need to improve the treatment of Tourette Syndrome (TS), Tic Disorders, and co-occurring conditions. The TAA has a track record of funding the development, evaluation and dissemination of effective treatments including pharmacological, behavioral and alternative therapies that reduce the burden of TS and Tic Disorders on our community. Based on currently available evidence, we provide here our current summary of the existing literature on the use of medical marijuana (cannabis) and cannabis-based medications for TS:

A reduction in tics with medical marijuana and cannabis-based medicines has been reported in small studies, patient reports and anecdotal case reports. The neurobiological pathways targeted by medical marijuana and related therapies are deserving of more research and larger scale studies.
There is the potential for adverse effects from medical marijuana and related plant-derived extracts that raise concern for treatment, especially in children and adolescents.
The TAA supports removing regulatory barriers to allow for large-scale research studies of medical marijuana. There is currently insufficient scientific evidence to reach a definitive conclusion on the efficacy and safety of medical marijuana, cannabis-based medications, or related plant-derived extracts for the treatment of TS and other Tic Disorders.
