Most of the evidence for the efficacy of medical marijuana in treating writer’s cramp is anecdotal. Clinical research is sorely lacking. However, there has been some research into other neurological disorders that can be treated with medical marijuana. These include multiple sclerosis, tinnitus and other dystonia disorders, of which writer’s cramp is one. Muscle spasticity can be reduced in multiple sclerosis with the use of medical marijuana. The ringing in one’s ears can be lessened when tinnitus sufferers are treated with medical marijuana and a number of other neurological symptoms are being perceived by patients or observed by doctors as relieved by medical marijuana.
One open trial on five patients with dystonia disorders like writer’s cramp showed that all five patients showed improvement. Another study conducted on hamsters used a synthetic cannabinoid to treat dystonia. The hamsters also showed marked improvement with use of the drug. These trials show that medical marijuana has the potential to treat dystonia disorders like writer’s cramp. Other trials show that medical marijuana can treat dystonia in patients with other diseases causing said dystonia. One example of a condition that can cause dystonia is Wilson’s disease.
According to a study published in 2004 by the Movement Disorder Society, medical marijuana was used to treat a woman who suffered from dystonia caused by Wilson’s disease. The woman improved greatly after inhaling medical marijuana. The dystonia itself differed from writer’s cramp in that it was generalized. However, it is thought that all dystonia stems from the same area of the brain. Therefore, the same reaction that gave this woman relief from her dystonia symptoms could potentially do the same for sufferers of writer’s cramp.
Another study published by the Movement Disorder Society in 2004 focused on an individual with musician’s cramp. Musician’s cramp is very similar to writer’s cramp. In fact, it is possible that they are identical and they are often grouped together as one disorder. The study showed that tetrahydrocannibinol or THC was useful in treating the patient’s musician’s cramp. Given the similarities and potentially identical nature of musician’s cramp and writer’s cramp, it is reasonable to say that the same results being reported by writer’s cramp patients are supported by this study.
