BERLIN (Reuters Health) - Chemicals found in cannabis can significantly reduce the symptoms of Tourette's syndrome, study findings suggest.
Tourette's syndrome is a neurological condition characterized by uncontrollable facial grimaces, tics, and involuntary grunts, snorts and shouts.
Dr. Kirsten Mueller-Vahl of the Hanover Medical College in Germany led a team that investigated the effects of chemicals called cannabinols in 12 adult Tourette's patients.
In the study, each patient was given a single oral dose of d9-THC--the most psychoactive chemical in cannabis--calculated based on their body weight, sex, age and prior use of marijuana, or a dose of inactive placebo. Symptoms were measured after the first treatment, and compared to symptoms after the same patient was switched to the other pill. Neither the patient nor the investigator knew whether they were given a placebo or the active treatment first.
A single dose of the cannabinol produced a significant reduction in symptoms for several hours compared to placebo, the researchers report in the April issue of Pharmacopsychiatry.
"The effects were clear," Mueller-Vahl told Reuters Health. "What was also interesting was that some patients experienced far greater effects than others. Some had a great effect, some only (a small effect), and a few none at all. But generally, the level of tic activity was reduced as were the compulsions, such as to shout, spit or swear."
