A new Czech study finds that marijuana use may ease Parkinson's Disease symptoms:

"Nearly half of Parkinson's disease patients who have tried marijuana say the drug helped relieve their symptoms, according to a survey of patients with the degenerative neurological disorder. Dr. Evzin Ruzicka, an attending neurologist at Charles University in Prague in the Czech Republic, reported the findings here at the Movement Disorders Society's Seventh International Congress of Parkinson's Disease and Movement Disorders. Ruzicka is also a consultant at the Prague Movement Disorders Center. "

"Daily marijuana users reported more improvement in their dyskinesias than those using it less often. The investigators speculated that the effect of cannabis on Parkinson's disease symptoms may be due to interaction among cannabis, certain brain receptors that respond to cannabis and endogenous cannabinoids or cannabis-like substances within the body."
